music is considered as the greatest art that makes the mood of person good to bad and can also make to bad to good
Music is an art form whose medium is sound and silence. Its common elements are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (mousike; "art of the Muses").[1]
The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and subgenres, although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within "the arts", music may be classified as a performing art, a fine art, and auditory art. It may also be divided among "art music" and "folk music". There is also a strong connection between music and mathematics.[2] Music may be played and heard live, may be part of a dramatic work or film, or may be recorded.
To many people in many cultures, music is an important part of their way of life. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."[3] Musicologist Jean-Jacques Nattiez summarizes the relativist, post-modern viewpoint: "The border between music and noise is always culturally defined—which implies that, even within a single society, this border does not always pass through the same place; in short, there is rarely a consensus ... By all accounts there is no single and intercultural universal concept defining what music might be."[4]
The medieval era (476 AD to 1400 AD) started with the introduction of chanting into Roman Catholic Church
services. Western Music then started becoming more of an art form with
the advances in music notation. The only European Medieval repertory
that survives from before about 800 is the monophonic liturgical plainsong of the Roman Catholic Church, the central tradition of which was called Gregorian chant. Alongside these traditions of sacred and church music there existed a vibrant tradition of secular song. Examples of composers from this period are Léonin, Pérotin and Guillaume de Machaut. From the Renaissance music era, much of the surviving music of 14th-century Europe is secular. By the middle of the 15th century, composers and singers used a smooth polyphony for sacred musical compositions. Prominent composers from this era are Guillaume Dufay, Giovanni Pierluigi da Palestrina, Thomas Morley, and Orlande de Lassus.
Renaissance music (c. 1400 A.D. to 1600 A.D.) was more focused on secular themes. Around 1450, the printing
press was invented, and that helped to disseminate musical styles more
quickly and across a larger area. Thus, music could play an increasingly
important role in daily life. Musicians worked for the church, courts
and towns. Church choirs grew in size, and the church remained an
important patron of music. However, musical activity shifted to the
courts. Kings and princes competed for the finest composers.
Many leading important composers came from Holland, Belgium, and northern France, called the Franco-Flemish composers. They held important positions throughout Europe, especially in Italy. Other countries with vibrant musical lives include Germany, England, and Spain.
The Baroque era of music took place from 1600 to 1750, as the Baroque artistic style flourished across Europe; and during this time, music expanded in its range and complexity. Baroque music began when the first operas were written and when contrapuntal music became prevalent. German Baroque composers wrote for small ensembles including strings, brass, and woodwinds, as well as choirs, pipe organ, harpsichord, and clavichord.
During this period several major music forms were defined that lasted
into later periods when they were expanded and evolved further,
including the fugue, the invention, the sonata, and the concerto.[15]
The late Baroque style was polyphonically complex and ornamental and
rich in its melodies. Composers from the Baroque era include Johann Sebastian Bach, George Frideric Handel, and Georg Philipp Telemann.
The music of the Classical Period
(1750 A.D. to 1830 A.D.) looked to the art and philosophy of Ancient
Greece and Rome, to the ideals of balance, proportion and disciplined
expression. It has a lighter, clearer and considerably simpler texture,
and tended to be almost voicelike and singable. New genres were
discovered. The main style was the homophony,[16] where prominent melody and accompaniment are clearly distinct.
Importance was given to instrumental music. It was dominated by further evolution of musical forms initially defined in the Baroque period: the sonata, the concerto, and the symphony. Others main kinds were trio, string quartet, serenade and divertimento. The sonata was the most important and developed form. Although Baroque composers also wrote sonatas, the Classical style of sonata is completely distinct. All of the main instrumental forms of the Classical era were based on the dramatic structure of the sonata.
One of the most important evolutionary steps made in the Classical period was the development of public concerts. The aristocracy would still play a significant role in the sponsorship of musical life, but it was now possible for composers to survive without being its permanent employees. The increasing popularity led to a growth in both the number and range of the orchestras. The expansion of orchestral concerts necessitated large public spaces. As a result of all these processes, symphonic music (including opera, ballet and oratorio) became more extroverted.
The best known composers of Classicism are Carl Philipp Emanuel Bach, Christoph Willibald Gluck, Johann Christian Bach, Joseph Haydn, Wolfgang Amadeus Mozart, Ludwig van Beethoven and Franz Schubert. Beethoven and Schubert are also considered to be composers in evolution towards Romanticism.
Romantic Music
(c. 1810 A.D. to 1900 A.D.) turned the rigid styles and forms of the
Classical era into more passionate and expressive pieces. It attempted
to increase emotional expression and power to describe deeper truths or
human feelings. The emotional and expressive qualities of music came to
take precedence over technique and tradition. Romantic composers grew in
idiosyncrasy, and went further in the syncretism of different art-forms
(such as literature), history (historical figures), or nature itself
with music. Romantic love was a prevalent theme in many works composed
during this period. In some cases the formal structures from the
classical period were preserved, but in many others existing genres,
forms, and functions were improved. Also, new forms were created that
were deemed better suited to the new subject matter. Opera and ballet continued to evolve.[13]
In 1800, the music developed by Ludwig van Beethoven and Franz Schubert introduced a more dramatic, expressive style. In Beethoven's case, motifs, developed organically, came to replace melody as the most significant compositional unit. Later Romantic composers such as Pyotr Ilyich Tchaikovsky, Antonín Dvořák, and Gustav Mahler used more elaborated chords and more dissonance to create dramatic tension. They generated complex and often much longer musical works. During Romantic period tonality was at its peak. The late 19th century saw a dramatic expansion in the size of the orchestra, and in the role of concerts as part of urban society. It also saw a new diversity in theatre music, including operetta, and musical comedy and other forms of musical theatre.[13]
Indian classical music is one of the oldest musical traditions in the world.[17] The Indus Valley civilization has sculptures that show dance[18]
and old musical instruments, like the seven holed flute. Various types
of stringed instruments and drums have been recovered from Harrappa and Mohenjo Daro by excavations carried out by Sir Mortimer Wheeler.[19] The Rigveda has elements of present Indian music, with a musical notation to denote the metre and the mode of chanting.[20] Indian classical music (marga) is monophonic, and based on a single melody line or raga rhythmically organized through talas.
Hindustani music was influenced by the Persian performance practices of
the Afghan Mughals. Carnatic music popular in the southern states, is
largely devotional; the majority of the songs are addressed to the Hindu
deities. There are a lot of songs emphasising love and other social
issues.
Asian music covers the music cultures of Arabia, Central Asia, East Asia, South Asia, and Southeast Asia. Chinese classical music, the traditional art or court music of China, has a history stretching over around three thousand years. It has its own unique systems of musical notation, as well as musical tuning and pitch, musical instruments and styles or musical genres. Chinese music is pentatonic-diatonic, having a scale of twelve notes to an octave (5 + 7 = 12) as does European-influenced music. Persian music is the music of Persia and Persian language countries: musiqi, the science and art of music, and muzik, the sound and performance of music (Sakata 1983). See also: Music of Iran, Music of Afghanistan, Music of Tajikistan, Music of Uzbekistan.
Jazz evolved and became an important genre of music over the course of the 20th century, and during the second half of that century, rock music did the same. Jazz is an American musical artform that originated in the beginning of the 20th century in African American communities in the Southern United States from a confluence of African and European music traditions. The style's West African pedigree is evident in its use of blue notes, improvisation, polyrhythms, syncopation, and the swung note.[22] From its early development until the present, jazz has also incorporated music from 19th- and 20th-century American popular music.[23] Jazz has, from its early-20th-century inception, spawned a variety of subgenres, ranging from New Orleans Dixieland (1910s) to 1970s and 1980s-era jazz-rock fusion.
Rock music is a genre of popular music that developed in the 1960s from 1950s rock and roll, rockabilly, blues, and country music. The sound of rock often revolves around the electric guitar or acoustic guitar, and it uses a strong back beat laid down by a rhythm section of electric bass guitar, drums, and keyboard instruments such as organ, piano, or, since the 1970s, analog synthesizers and digital ones and computers since the 1990s. Along with the guitar or keyboards, saxophone and blues-style harmonica are used as soloing instruments. In its "purest form," it "has three chords, a strong, insistent back beat, and a catchy melody."[24] In the late 1960s and early 1970s, it branched out into different subgenres, ranging from blues rock and jazz-rock fusion to heavy metal and punk rock, as well as the more classical influenced genre of progressive rock and several types of experimental rock genres.
Many cultures include strong traditions of solo and performance, such as in Indian classical music, and in the Western art-music tradition. Other cultures, such as in Bali, include strong traditions of group performance. All cultures include a mixture of both, and performance may range from improvised solo playing for one's enjoyment to highly planned and organised performance rituals such as the modern classical concert, religious processions, music festivals or music competitions. Chamber music, which is music for a small ensemble with only a few of each type of instrument, is often seen as more intimate than symphonic works.
In popular music and jazz, music notation almost always indicates only the basic framework of the melody, harmony, or performance approach; musicians and singers are expected to know the performance conventions and styles associated with specific genres and pieces. For example, the "lead sheet" for a jazz tune may only indicate the melody and the chord changes. The performers in the jazz ensemble are expected to know how to "flesh out" this basic structure by adding ornaments, improvised music, and chordal accompaniment.
There are often many links between amateur and professional musicians. Beginning amateur musicians take lessons with professional musicians. In community settings, advanced amateur musicians perform with professional musicians in a variety of ensembles and orchestras. In some cases, amateur musicians attain a professional level of competence, and they are able to perform in professional performance settings. A distinction is often made between music performed for the benefit of a live audience and music that is performed for the purpose of being recorded and distributed through the music retail system or the broadcasting system. However, there are also many cases where a live performance in front of an audience is recorded and distributed (or broadcast).
In some musical genres, such as jazz and blues, even more freedom is given to the performer to engage in improvisation on a basic melodic, harmonic, or rhythmic framework. The greatest latitude is given to the performer in a style of performing called free improvisation, which is material that is spontaneously "thought of" (imagined) while being performed, not preconceived. Improvised music usually follows stylistic or genre conventions and even "fully composed" includes some freely chosen material. Composition does not always mean the use of notation, or the known sole authorship of one individual. Music can also be determined by describing a "process" that creates musical sounds. Examples of this range from wind chimes, through computer programs that select sounds. Music from random elements is called Aleatoric music, and is associated with such composers as John Cage, Morton Feldman, and Witold Lutosławski.
Music can be composed for repeated performance or it can be improvised: composed on the spot. The music can be performed entirely from memory, from a written system of musical notation, or some combination of both. Study of composition has traditionally been dominated by examination of methods and practice of Western classical music, but the definition of composition is broad enough to include spontaneously improvised works like those of free jazz performers and African drummers such as the Ewe drummers.
In popular music, guitarists and electric bass players often read music notated in tablature (often abbreviated as "tab"), which indicates the location of the notes to be played on the instrument using a diagram of the guitar or bass fingerboard. Tabulature was also used in the Baroque era to notate music for the lute, a stringed, fretted instrument. Notated music is produced as sheet music. To perform music from notation requires an understanding of both the rhythmic and pitch elements embodied in the symbols and the performance practice that is associated with a piece of music or a genre. In improvisation, the performer often plays from music where only the chord changes are written, requiring a great understanding of the music's structure and chord progressions.
Pitch is a subjective sensation, reflecting generally the lowness or highness of a sound. Rhythm is the arrangement of sounds and silences in time. Meter animates time in regular pulse groupings, called measures or bars. A melody is a series of notes sounding in succession. The notes of a melody are typically created with respect to pitch systems such as scales or modes. Harmony is the study of vertical sonorities in music. Vertical sonority refers to considering the relationships between pitches that occur together; usually this means at the same time, although harmony can also be implied by a melody that outlines a harmonic structure. Notes can be arranged into different scales and modes. Western music theory generally divides the octave into a series of 12 notes that might be included in a piece of music. In music written using the system of major-minor tonality, the key of a piece determines the scale used. Musical texture is the overall sound of a piece of music commonly described according to the number of and relationship between parts or lines of music: monophony, heterophony, polyphony, homophony, or monody.
Timbre, sometimes called "Color" or "Tone Color" is the quality or sound of a voice or instrument.[26] Expressive Qualities are those elements in music that create change in music that are not related to pitch, rhythm or timbre. They include Dynamics and Articulation. Form is a facet of music theory that explores the concept of musical syntax, on a local and global level. Examples of common forms of Western music include the fugue, the invention, sonata-allegro, canon, strophic, theme and variations, and rondo. Popular Music often makes use of strophic form often in conjunction with Twelve bar blues. Analysis is the effort to describe and explain music.
In the 20th century, important contributions were made by Peter Kivy, Jerrold Levinson, Roger Scruton, and Stephen Davies. However, many musicians, music critics, and other non-philosophers have contributed to the aesthetics of music. In the 19th century, a significant debate arose between Eduard Hanslick, a music critic and musicologist, and composer Richard Wagner. Harry Partch and some other musicologists, such as Kyle Gann, have studied and tried to popularize microtonal music and the usage of alternate musical scales. Also many modern composers like Lamonte Young, Rhys Chatham and Glenn Branca paid much attention to a scale called just intonation.
It is often thought that music has the ability to affect our emotions, intellect, and psychology; it can assuage our loneliness or incite our passions. The philosopher Plato suggests in the Republic that music has a direct effect on the soul. Therefore, he proposes that in the ideal regime music would be closely regulated by the state. (Book VII)
There has been a strong tendency in the aesthetics of music to emphasize the paramount importance of compositional structure; however, other issues concerning the aesthetics of music include lyricism, harmony, hypnotism, emotiveness, temporal dynamics, resonance, playfulness, and color (see also musical development).
Deaf people can experience music by feeling the vibrations in their body, a process that can be enhanced if the individual holds a resonant, hollow object. A well-known deaf musician is the composer Ludwig van Beethoven, who composed many famous works even after he had completely lost his hearing. Recent examples of deaf musicians include Evelyn Glennie, a highly acclaimed percussionist who has been deaf since age twelve, and Chris Buck, a virtuoso violinist who has lost his hearing. This is relevant because it indicates that music is a deeper cognitive process than unexamined phrases such as, "pleasing to the ear" suggests. Much research in music cognition seeks to uncover these complex mental processes involved in listening to music, which may seem intuitively simple, yet are vastly intricate and complex.
Montreal Neurological Institute researcher Valorie Salimpoor and her colleagues have now shown that the pleasurable feelings associated with emotional music are the result of dopamine release in the striatum--the same anatomical areas that underpin the anticipatory and rewarding aspects of drug addiction.[27]
Cognitive neuroscience of music is distinguished from related fields such as music psychology, music cognition and cognitive musicology in its reliance on direct observations of the brain, using such techniques as functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS), magnetoencephalography (MEG), electroencephalography (EEG), and positron emission tomography (PET).
Music is an art form whose medium is sound and silence. Its common elements are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (mousike; "art of the Muses").[1]
The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and subgenres, although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within "the arts", music may be classified as a performing art, a fine art, and auditory art. It may also be divided among "art music" and "folk music". There is also a strong connection between music and mathematics.[2] Music may be played and heard live, may be part of a dramatic work or film, or may be recorded.
To many people in many cultures, music is an important part of their way of life.

Prehistoric eras
Main article: Prehistoric music
Prehistoric music can only be theorized based on findings from paleolithic archaeology sites. Flutes
are often discovered, carved from bones in which lateral holes have
been pierced; these are thought to have been blown at one end like the
Japanese shakuhachi. The Divje Babe flute, carved from a cave bear femur, is thought to be at least 40,000 years old. Instruments such as the seven-holed flute and various types of stringed instruments have been recovered from the Indus Valley Civilization archaeological sites.[5] India has one of the oldest musical traditions in the world—references to Indian classical music (marga) are found in the Vedas, ancient scriptures of the Hindu tradition.[6] The earliest and largest collection of prehistoric musical instruments was found in China and dates back to between 7000 and 6600 BC.[7] The Hurrian song, found on clay tablets that date back to approximately 1400 BC, is the oldest surviving notated work of music.Ancient Egypt
Main article: Music of Egypt
The ancient Egyptians credited one of their gods, Thoth, with the invention of music, which Osiris
in turn used as part of his effort to civilize the world. The earliest
material and representational evidence of Egyptian musical instruments
dates to the Predynastic period, but the evidence is more securely attested in the Old Kingdom when harps, flutes and double clarinets were played.[8] Percussion instruments, lyres and lutes were added to orchestras by the Middle Kingdom. Cymbals[9] frequently accompanied music and dance, much as they still do in Egypt today. Egyptian folk music, including the traditional Sufi dhikr rituals, are the closest contemporary music genre to ancient Egyptian music, having preserved many of its features, rhythms and instruments.[10][11]References in the Bible
Main article: History of music in the biblical period
Music and theatre scholars studying the history and anthropology of Semitic and early Judeo-Christian culture have discovered common links in theatrical and musical activity between the classical cultures of the Hebrews and those of later Greeks and Romans. The common area of performance is found in a "social phenomenon called litany," a form of prayer consisting of a series of invocations or supplications. The Journal of Religion and Theatre notes that among the earliest forms of litany, "Hebrew litany was accompanied by a rich musical tradition:"[12]- "While Genesis 4.21 identifies Jubal as the “father of all such as handle the harp and pipe,” the Pentateuch is nearly silent about the practice and instruction of music in the early life of Israel. Then, in I Samuel 10 and the texts that follow, a curious thing happens. “One finds in the biblical text,” writes Alfred Sendrey, “a sudden and unexplained upsurge of large choirs and orchestras, consisting of thoroughly organized and trained musical groups, which would be virtually inconceivable without lengthy, methodical preparation.” This has led some scholars to believe that the prophet Samuel was the patriarch of a school, which taught not only prophets and holy men, but also sacred-rite musicians. This public music school, perhaps the earliest in recorded history, was not restricted to a priestly class—which is how the shepherd boy David appears on the scene as a minstrel to King Saul."[12]
Antiquity
Western cultures have had a major influence on the development of music. The history of the music of the Western cultures can be traced back to Ancient Greece times.Ancient Greece
Music was an important part of social and cultural life in Ancient Greece. Musicians and singers played a prominent role in Greek theater.[13] Mixed-gender choruses performed for entertainment, celebration, and spiritual ceremonies.[14] Instruments included the double-reed aulos and a plucked string instrument, the lyre, principally the special kind called a kithara. Music was an important part of education, and boys were taught music starting at age six. Greek musical literacy created a flowering of music development. Greek music theory included the Greek musical modes, that eventually became the basis for Western religious and classical music. Later, influences from the Roman Empire, Eastern Europe, and the Byzantine Empire changed Greek music. The Seikilos epitaph is the oldest surviving example of a complete musical composition, including musical notation, from anywhere in the world.The Middle Ages

Importance was given to instrumental music. It was dominated by further evolution of musical forms initially defined in the Baroque period: the sonata, the concerto, and the symphony. Others main kinds were trio, string quartet, serenade and divertimento. The sonata was the most important and developed form. Although Baroque composers also wrote sonatas, the Classical style of sonata is completely distinct. All of the main instrumental forms of the Classical era were based on the dramatic structure of the sonata.
One of the most important evolutionary steps made in the Classical period was the development of public concerts. The aristocracy would still play a significant role in the sponsorship of musical life, but it was now possible for composers to survive without being its permanent employees. The increasing popularity led to a growth in both the number and range of the orchestras. The expansion of orchestral concerts necessitated large public spaces. As a result of all these processes, symphonic music (including opera, ballet and oratorio) became more extroverted.
The best known composers of Classicism are Carl Philipp Emanuel Bach, Christoph Willibald Gluck, Johann Christian Bach, Joseph Haydn, Wolfgang Amadeus Mozart, Ludwig van Beethoven and Franz Schubert. Beethoven and Schubert are also considered to be composers in evolution towards Romanticism.

20th- and 21st-century music
Main article: 20th-century music
With 20th-century music, there was a vast increase in music listening as the radio gained popularity and phonographs were used to replay and distribute music. The focus of art music was characterized by exploration of new rhythms, styles, and sounds. Igor Stravinsky, Arnold Schoenberg, and John Cage
were all influential composers in 20th-century art music. The invention
of sound recording and the ability to edit music gave rise to new
sub-genre of classical music, including the acousmatic [21] and Musique concrète schools of electronic composition.Jazz evolved and became an important genre of music over the course of the 20th century, and during the second half of that century, rock music did the same. Jazz is an American musical artform that originated in the beginning of the 20th century in African American communities in the Southern United States from a confluence of African and European music traditions. The style's West African pedigree is evident in its use of blue notes, improvisation, polyrhythms, syncopation, and the swung note.[22] From its early development until the present, jazz has also incorporated music from 19th- and 20th-century American popular music.[23] Jazz has, from its early-20th-century inception, spawned a variety of subgenres, ranging from New Orleans Dixieland (1910s) to 1970s and 1980s-era jazz-rock fusion.
Rock music is a genre of popular music that developed in the 1960s from 1950s rock and roll, rockabilly, blues, and country music. The sound of rock often revolves around the electric guitar or acoustic guitar, and it uses a strong back beat laid down by a rhythm section of electric bass guitar, drums, and keyboard instruments such as organ, piano, or, since the 1970s, analog synthesizers and digital ones and computers since the 1990s. Along with the guitar or keyboards, saxophone and blues-style harmonica are used as soloing instruments. In its "purest form," it "has three chords, a strong, insistent back beat, and a catchy melody."[24] In the late 1960s and early 1970s, it branched out into different subgenres, ranging from blues rock and jazz-rock fusion to heavy metal and punk rock, as well as the more classical influenced genre of progressive rock and several types of experimental rock genres.
Performance
Main article: Performance
Performance is the physical expression of music. Often, a musical
work is performed once its structure and instrumentation are
satisfactory to its creators; however, as it gets performed, it can
evolve and change. A performance can either be rehearsed or improvised.
Improvisation is a musical idea created without premeditation, while
rehearsal is vigorous repetition of an idea until it has achieved
cohesion. Musicians will sometimes add improvisation to a well-rehearsed idea to create a unique performance.Many cultures include strong traditions of solo and performance, such as in Indian classical music, and in the Western art-music tradition. Other cultures, such as in Bali, include strong traditions of group performance. All cultures include a mixture of both, and performance may range from improvised solo playing for one's enjoyment to highly planned and organised performance rituals such as the modern classical concert, religious processions, music festivals or music competitions. Chamber music, which is music for a small ensemble with only a few of each type of instrument, is often seen as more intimate than symphonic works.
Aural tradition
Many types of music, such as traditional blues and folk music were originally preserved in the memory of performers, and the songs were handed down orally, or aurally (by ear). When the composer of music is no longer known, this music is often classified as "traditional." Different musical traditions have different attitudes towards how and where to make changes to the original source material, from quite strict, to those that demand improvisation or modification to the music. A culture's history may also be passed by ear through song.Ornamentation
Main article: Ornament (music)
The detail included explicitly in the music notation
varies between genres and historical periods. In general, art music
notation from the 17th through the 19th century required performers to
have a great deal of contextual knowledge about performing styles. For
example, in the 17th and 18th century, music notated for solo performers
typically indicated a simple, unadorned melody. However, performers
were expected to know how to add stylistically appropriate ornaments,
such as trills and turns.
In the 19th century, art music for solo performers may give a general
instruction such as to perform the music expressively, without
describing in detail how the performer should do this. The performer was
expected to know how to use tempo changes, accentuation, and pauses
(among other devices) to obtain this "expressive" performance style. In
the 20th century, art music notation often became more explicit and
used a range of markings and annotations to indicate to performers how
they should play or sing the piece.In popular music and jazz, music notation almost always indicates only the basic framework of the melody, harmony, or performance approach; musicians and singers are expected to know the performance conventions and styles associated with specific genres and pieces. For example, the "lead sheet" for a jazz tune may only indicate the melody and the chord changes. The performers in the jazz ensemble are expected to know how to "flesh out" this basic structure by adding ornaments, improvised music, and chordal accompaniment.
Production
Main article: Music production
Music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes, or as an entertainment
product for the marketplace. Amateur musicians compose and perform
music for their own pleasure, and they do not derive their income from
music. Professional musicians are employed by a range of institutions
and organisations, including armed forces, churches and synagogues,
symphony orchestras, broadcasting or film production companies, and music schools. Professional musicians sometimes work as freelancers, seeking contracts and engagements in a variety of settings.There are often many links between amateur and professional musicians. Beginning amateur musicians take lessons with professional musicians. In community settings, advanced amateur musicians perform with professional musicians in a variety of ensembles and orchestras. In some cases, amateur musicians attain a professional level of competence, and they are able to perform in professional performance settings. A distinction is often made between music performed for the benefit of a live audience and music that is performed for the purpose of being recorded and distributed through the music retail system or the broadcasting system. However, there are also many cases where a live performance in front of an audience is recorded and distributed (or broadcast).
Composition
Main article: Musical composition
"Composition" is often classed as the creation and recording of music
via a medium by which others can interpret it (i.e., paper or sound).
Many cultures use at least part of the concept of preconceiving musical
material, or composition, as held in western classical music.
Even when music is notated precisely, there are still many decisions
that a performer has to make. The process of a performer deciding how to
perform music that has been previously composed and notated is termed
interpretation. Different performers' interpretations of the same music
can vary widely. Composers and song writers who present their own music
are interpreting, just as much as those who perform the music of others
or folk music. The standard body of choices and techniques present at a
given time and a given place is referred to as performance practice,
whereas interpretation is generally used to mean either individual
choices of a performer, or an aspect of music that is not clear, and
therefore has a "standard" interpretation.In some musical genres, such as jazz and blues, even more freedom is given to the performer to engage in improvisation on a basic melodic, harmonic, or rhythmic framework. The greatest latitude is given to the performer in a style of performing called free improvisation, which is material that is spontaneously "thought of" (imagined) while being performed, not preconceived. Improvised music usually follows stylistic or genre conventions and even "fully composed" includes some freely chosen material. Composition does not always mean the use of notation, or the known sole authorship of one individual. Music can also be determined by describing a "process" that creates musical sounds. Examples of this range from wind chimes, through computer programs that select sounds. Music from random elements is called Aleatoric music, and is associated with such composers as John Cage, Morton Feldman, and Witold Lutosławski.
Music can be composed for repeated performance or it can be improvised: composed on the spot. The music can be performed entirely from memory, from a written system of musical notation, or some combination of both. Study of composition has traditionally been dominated by examination of methods and practice of Western classical music, but the definition of composition is broad enough to include spontaneously improvised works like those of free jazz performers and African drummers such as the Ewe drummers.
Notation
Main article: Musical notation
Notation is the written expression of music notes and rhythms on
paper using symbols. When music is written down, the pitches and rhythm
of the music is notated, along with instructions on how to perform the
music. The study of how to read notation involves music theory, harmony,
the study of performance practice, and in some cases an understanding
of historical performance methods. Written notation varies with style
and period of music. In Western Art music, the most common types of
written notation are scores, which include all the music parts of an
ensemble piece, and parts, which are the music notation for the
individual performers or singers. In popular music, jazz, and blues, the
standard musical notation is the lead sheet, which notates the melody,
chords, lyrics
(if it is a vocal piece), and structure of the music. Scores and parts
are also used in popular music and jazz, particularly in large ensembles
such as jazz "big bands."In popular music, guitarists and electric bass players often read music notated in tablature (often abbreviated as "tab"), which indicates the location of the notes to be played on the instrument using a diagram of the guitar or bass fingerboard. Tabulature was also used in the Baroque era to notate music for the lute, a stringed, fretted instrument. Notated music is produced as sheet music. To perform music from notation requires an understanding of both the rhythmic and pitch elements embodied in the symbols and the performance practice that is associated with a piece of music or a genre. In improvisation, the performer often plays from music where only the chord changes are written, requiring a great understanding of the music's structure and chord progressions.
Improvisation
Musical improvisation is the creation of spontaneous music. Improvisation is often considered an act of instantaneous composition by performers, where compositional techniques are employed with or without preparation. Improvisation is a major part of some types of music, such as blues, jazz, and jazz fusion, in which instrumental performers improvise solos and melody lines. In the Western art music tradition, improvisation was an important skill during the Baroque era and during the Classical era; solo performers and singers improvised virtuoso cadenzas during concerts. However, in the 20th and 21st century, improvisation played a smaller role in Western Art music.Theory
Main article: Music theory
Music theory encompasses the nature and mechanics of music. It often
involves identifying patterns that govern composers' techniques and
examining the language and notation of music. In a grand sense, music theory distills and analyzes the parameters or elements of music – rhythm, harmony (harmonic function), melody, structure, form, and texture. Broadly, music theory may include any statement, belief, or conception of or about music.[25] People who study these properties are known as music theorists. Some have applied acoustics, human physiology, and psychology to the explanation of how and why music is perceived.
Music has many different fundamentals or elements. These are, but are
not limited to: pitch, beat or pulse, rhythm, melody, harmony, texture,
allocation of voices, timbre or color, expressive qualities (dynamics
and articulation), and form or structure.Pitch is a subjective sensation, reflecting generally the lowness or highness of a sound. Rhythm is the arrangement of sounds and silences in time. Meter animates time in regular pulse groupings, called measures or bars. A melody is a series of notes sounding in succession. The notes of a melody are typically created with respect to pitch systems such as scales or modes. Harmony is the study of vertical sonorities in music. Vertical sonority refers to considering the relationships between pitches that occur together; usually this means at the same time, although harmony can also be implied by a melody that outlines a harmonic structure. Notes can be arranged into different scales and modes. Western music theory generally divides the octave into a series of 12 notes that might be included in a piece of music. In music written using the system of major-minor tonality, the key of a piece determines the scale used. Musical texture is the overall sound of a piece of music commonly described according to the number of and relationship between parts or lines of music: monophony, heterophony, polyphony, homophony, or monody.
Timbre, sometimes called "Color" or "Tone Color" is the quality or sound of a voice or instrument.[26] Expressive Qualities are those elements in music that create change in music that are not related to pitch, rhythm or timbre. They include Dynamics and Articulation. Form is a facet of music theory that explores the concept of musical syntax, on a local and global level. Examples of common forms of Western music include the fugue, the invention, sonata-allegro, canon, strophic, theme and variations, and rondo. Popular Music often makes use of strophic form often in conjunction with Twelve bar blues. Analysis is the effort to describe and explain music.
Philosophy and aesthetics
Main articles: Philosophy of music and Aesthetics of music
Philosophy of music is the study of fundamental questions regarding
music. The philosophical study of music has many connections with
philosophical questions in metaphysics and aesthetics. Some basic questions in the philosophy of music are:- What is the definition of music? (What are the necessary and sufficient conditions for classifying something as music?)
- What is the relationship between music and mind?
- What does musical history reveal to us about the world?
- What is the connection between music and emotions?
- What is meaning in relation to music?
In the 20th century, important contributions were made by Peter Kivy, Jerrold Levinson, Roger Scruton, and Stephen Davies. However, many musicians, music critics, and other non-philosophers have contributed to the aesthetics of music. In the 19th century, a significant debate arose between Eduard Hanslick, a music critic and musicologist, and composer Richard Wagner. Harry Partch and some other musicologists, such as Kyle Gann, have studied and tried to popularize microtonal music and the usage of alternate musical scales. Also many modern composers like Lamonte Young, Rhys Chatham and Glenn Branca paid much attention to a scale called just intonation.
It is often thought that music has the ability to affect our emotions, intellect, and psychology; it can assuage our loneliness or incite our passions. The philosopher Plato suggests in the Republic that music has a direct effect on the soul. Therefore, he proposes that in the ideal regime music would be closely regulated by the state. (Book VII)
There has been a strong tendency in the aesthetics of music to emphasize the paramount importance of compositional structure; however, other issues concerning the aesthetics of music include lyricism, harmony, hypnotism, emotiveness, temporal dynamics, resonance, playfulness, and color (see also musical development).
Cognition and psychology
Music cognition
Main article: Music cognition
The field of music cognition involves the study of many aspects of
music, including how it is processed by listeners. Rather than accepting
the standard practices of analyzing, composing, and performing music as
a given, much research in music cognition seeks instead to uncover the
mental processes that underlie these practices. Also, research in the
field seeks to uncover commonalities between the musical traditions of
disparate cultures and possible cognitive "constraints" that limit these
musical systems. Questions regarding musical innateness, and emotional
responses to music are also major areas of research in the field.Deaf people can experience music by feeling the vibrations in their body, a process that can be enhanced if the individual holds a resonant, hollow object. A well-known deaf musician is the composer Ludwig van Beethoven, who composed many famous works even after he had completely lost his hearing. Recent examples of deaf musicians include Evelyn Glennie, a highly acclaimed percussionist who has been deaf since age twelve, and Chris Buck, a virtuoso violinist who has lost his hearing. This is relevant because it indicates that music is a deeper cognitive process than unexamined phrases such as, "pleasing to the ear" suggests. Much research in music cognition seeks to uncover these complex mental processes involved in listening to music, which may seem intuitively simple, yet are vastly intricate and complex.
Montreal Neurological Institute researcher Valorie Salimpoor and her colleagues have now shown that the pleasurable feelings associated with emotional music are the result of dopamine release in the striatum--the same anatomical areas that underpin the anticipatory and rewarding aspects of drug addiction.[27]
Cognitive neuroscience of music
Main article: Cognitive neuroscience of music
Cognitive neuroscience of music is the scientific study of
brain-based mechanisms involved in the cognitive processes underlying
music. These behaviours include music listening, performing, composing,
reading, writing, and ancillary activities. It also is increasingly
concerned with the brain basis for musical aesthetics and musical
emotion. Scientists working in this field may have training in cognitive
neuroscience, neurology, neuroanatomy, psychology, music theory,
computer science, and other allied fields.Cognitive neuroscience of music is distinguished from related fields such as music psychology, music cognition and cognitive musicology in its reliance on direct observations of the brain, using such techniques as functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS), magnetoencephalography (MEG), electroencephalography (EEG), and positron emission tomography (PET).
Music psychology
Main article: Music psychology
Music psychology, or the psychology of music, may be regarded as a branch of psychology or a branch of musicology.
It aims to explain and understand musical behavior and musical
experience. Modern music psychology is mainly empirical:
music-psychological knowledge tends to advance primarily on the basis of
interpretations of data about musical behavior and experience, which
are collected by systematic observation of and interaction with human
participants. Music psychology is a field of research with practical
relevance for music performance, music composition, music education, music medicine, and music therapy.
