EVOLUTION OF MUSIC
Music is an art form and cultural activity whose medium is sound organized in time. The common elements of music are pitch (which governs melody andharmony), rhythm (and its associated concepts tempo, meter, and articulation),dynamics (loudness and softness), and the sonic qualities of timbre and texture(which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumentalaccompaniment) and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; "art of the Muses").[1] See glossary of musical terminology.

In its most general form, the activities describing music as an art form orcultural activity include the creation of works of music (songs, tunes,symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. 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 Cagethought that any sound can be music, saying, for example, "There is no noise, only sound."[2]
The creation, performance, significance, and even the definition of music vary according to culture and social context. Indeed, throughout history, some new forms or styles of music have been criticized as "not being music", includingBeethoven's Grosse Fuge string quartet in 1825,[3] early jazz in the beginning of the 1900s[4] and hardcore punk in the 1980s.[5] There are many types of music, including popular music, traditional music, art music, music written for religious ceremonies and work songs such as chanteys. Music ranges from strictly organized compositions–such as Classical music symphonies from the 1700s and 1800s, through to spontaneously played improvisational music such asjazz, and avant-garde styles of chance-based contemporary music from the 20th and 21st centuries.
Music can be divided into genres (e.g., country music) and genres can be further divided into subgenres (e.g., country blues and pop country are two of the many country subgenres), although the dividing lines and relationships between music genres are often subtle, sometimes open to personal interpretation, and occasionally controversial. For example, it can be hard to draw the line between some early 1980s hard rock and heavy metal. Within the arts, music may be classified as a performing art, a fine art or as an auditory art. Music may be played or sung and heard live at a rock concert or orchestra performance, heard live as part of a dramatic work (a music theater show or opera), or it may be recorded and listened to on a radio, MP3 player, CD player,smartphone or as film score or TV show.
In many cultures, music is an important part of people's way of life, as it plays a key role in religious rituals, rite of passage ceremonies (e.g., graduation and marriage), social activities (e.g., dancing) and cultural activities ranging from amateur karaoke singing to playing in an amateur funk band or singing in a community choir. People may make music as a hobby, like a teen playing cello in a youth orchestra, or work as a professional musician or singer. The music industry includes the individuals who create new songs and musical pieces (such as songwriters and composers), individuals who perform music (which include orchestra, jazz band and rock band musicians, singers and conductors), individuals who record music (music producers and sound engineers), individuals who organize concert tours, and individuals who sell recordings and sheet music and scores to customers.
Etymology
As a form of art or entertainment
Music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes, or as an entertainment product for the marketplace. When music was only available through sheet music scores, such as during the Classical and Romantic eras, music lovers would buy thesheet music of their favourite pieces and songs so that they could perform them at home on the piano. With the advent of sound recording, records of popular songs, rather than sheet music became the dominant way that music lovers would enjoy their favourite songs. With the advent of home tape recorders in the 1980s and digital music in the 1990s, music lovers could make tapes or playlists of their favourite songs and take them with them on aportable cassette player or MP3 player. Some music lovers create mix tapes of their favorite songs, which serve as a "self-portrait, a gesture of friendship, prescription for an ideal party... [and] an environment consisting solely of what is most ardently loved."[7]
Amateur musicians can compose or perform music for their own pleasure, and derive their income elsewhere. Professional musicians are employed by a range of institutions and organisations, including armed forces (in marching bands, concert bands and popular music groups), churches and synagogues, symphony orchestras, broadcasting or film production companies, and music schools. Professional musicians sometimes work as freelancers or session musicians, 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 such as community concert bands and community orchestras.
A distinction is often made between music performed for a live audience and music that is performed in a studio so that it can be 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 also recorded and distributed. Live concert recordings are popular in both classical music and in popular music forms such as rock, where illegally taped live concerts are prized by music lovers. In the jam band scene, live, improvisedjam sessions are preferred to studio recordings.
Composition
"Composition" is the act or practice of creating a song, an instrumental musicpiece, a work with both singing and instruments, or another type of music. In many cultures, including Western classical music, the act of composing also includes the creation of music notation, such as a sheet music "score", which is then performed by the composer or by other singers or musicians. In popular music and traditional music, the act of composing, which is typically called songwriting, may involve the creation of a basic outline of the song, called thelead sheet, which sets out the melody, lyrics and chord progression. In classical music, the composer typically orchestrates his or her own compositions, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration. In some cases, a songwriter may not use notation at all, and instead compose the song in her mind and then play or record it from memory. In jazz and popular music, notable recordings by influential performers are given the weight that written scores play in classical music.
Even when music is notated relatively precisely, as in classical music, there are many decisions that a performer has to make, because notation does not specify all of the elements of music precisely. The process of deciding how to perform music that has been previously composed and notated is termed "interpretation". Different performers' interpretations of the same work of music can vary widely, in terms of the tempos that are chosen and the playing or singing style or phrasing of the melodies. Composers and songwriters who present their own music are interpreting their songs, just as much as those who perform the music of others. 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 the individual choices of a performer.[citation needed]
Although a musical composition often uses musical notation and has a single author, this is not always the case. A work of music can have multiple composers, which often occurs in popular music when a band collaborates to write a song, or in musical theatre, when one person writes the melodies, a second person writes the lyrics, and a third person orchestrates the songs. In some styles of music, such as the blues, a composer/songwriter may create, perform and record new songs or pieces without ever writing them down in music notation. A piece of music can also be composed with words, images, or computer programs that explain or notate how the singer or musician should create musical sounds. Examples range from avant-garde music that usesgraphic notation, to text compositions such as Aus den sieben Tagen, to computer programs that select sounds for musical pieces. Music that makes heavy use of randomness and chance is called aleatoric music, and is associated with contemporary composers active in the 20th century, such asJohn Cage, Morton Feldman, and Witold Lutosławski. A more commonly known example of chance-based music is the sound of wind chimes jingling in a breeze.
The 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 the creation of popular music andtraditional music songs and instrumental pieces as well as spontaneouslyimprovised works like those of free jazz performers and African percussionists such as Ewe drummers.
Notation
In the 2000s, music notation typically means the written expression of music notes and rhythms on paper using symbols. When music is written down, the pitches and rhythm of the music, such as the notes of a melody, are notated. Music notation also often provides instructions on how to perform the music. For example, the sheet music for a song may state that the song is a "slow blues" or a "fast swing", which indicates the tempo and the genre. To read music notation, a person must have an understanding of music theory,harmony and the performance practice associated with a particular song or piece's genre.
Written notation varies with style and period of music. In the 2000s, notated music is produced as sheet music or, for individuals with computer scorewriterprograms, as an image on a computer screen. In ancient times, music notation was put onto stone or clay tablets. To perform music from notation, a singer or instrumentalist requires an understanding of 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 genres requiring musical improvisation, the performer often plays from music where only the chord changes and form of the song are written, requiring the performer to have a great understanding of the music's structure, harmony and the styles of a particular genre (e.g., jazz orcountry 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.Fake books are also used in jazz; they may consist of lead sheets or simply chord charts, which permit rhythm section members to improvise anaccompaniment part to jazz songs. 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 intablature (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.
Improvisation
Musical improvisation is the creation of spontaneous music, often within (or based on) a pre-existing harmonic framework or chord progression. Improvisation is the 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, andjazz fusion, in which instrumental performers improvise solos, melody lines and accompaniment parts. In the Western art music tradition, improvisation was an important skill during the Baroque era and during the Classical era. In the Baroque era, performers improvised ornaments and basso continuo keyboard players improvised chord voicings based on figured bass notation. In the Classical era, solo performers and singers improvised virtuoso cadenzasduring concerts. However, in the 20th and early 21st century, as "common practice" Western art music performance became institutionalized in symphony orchestras, opera houses and ballets, improvisation has played a smaller role. At the same time, some modern composers have increasingly included improvisation in their creative work. In Indian classical music, improvisation is a core component and an essential criterion of performances.
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.[8] People who study these properties are known as music theorists. Some have appliedacoustics, human physiology, and psychology to the explanation of how and why music is perceived.
Elements
Music has many different fundamentals or elements. Depending on the definition of "element" being used, these can include: pitch, beat or pulse, tempo, rhythm, melody, harmony, texture, style, allocation of voices, timbre or color, dynamics, expression, articulation, form and structure. The elements of music feature prominently in the music curriculums of Australia, UK and US. All three curriculums identify pitch, dynamics, timbre and texture as elements, but the other identified elements of music are far from universally agreed. Below is a list of the three official versions of the "elements of music":
- Australia: pitch, timbre, texture, dynamics and expression, rhythm, form and structure.[9]
- UK: pitch, timbre, texture, dynamics, duration, tempo, structure.[10]
- USA: pitch, timbre, texture, dynamics, rhythm, form, harmony, style/articulation.[11]
In relation to the UK curriculum, in 2013 the term: "appropriate musical notations" was added to their list of elements and the title of the list was changed from the "elements of music" to the "inter-related dimensions of music". The inter-related dimensions of music are listed as: pitch, duration, dynamics, tempo, timbre, texture, structure and appropriate musical notations.[12]
The phrase "the elements of music" is used in a number of different contexts. The two most common contexts can be differentiated by describing them as the "rudimentary elements of music" and the "perceptual elements of music".
Rudimentary elements
In the 1800s, the phrases "the elements of music" and "the rudiments of music" were used interchangeably.[13][14] The elements described in these documents refer to aspects of music that are needed in order to become a musician, Recent writers such as Estrella [15] seem to be using the phrase "elements of music" in a similar manner. A definition which most accurately reflects this usage is: "the rudimentary principles of an art, science, etc.: the elements of grammar."[16] The UK's curriculum switch to the "inter-related dimensions of music" seems to be a move back to using the rudimentary elements of music.
Perceptual elements
Since the emergence of the study of psychoacoustics in the 1930s, most lists of elements of music have related more to how we hear music than how we learn to play it or study it. C.E. Seashore, in his book Psychology of Music,[17]identified four "psychological attributes of sound". These were: "pitch, loudness, time, and timbre" (p. 3). He did not call them the "elements of music" but referred to them as "elemental components" (p. 2). Nonetheless these elemental components link precisely with four of the most common musical elements: "Pitch" and "timbre" match exactly, "loudness" links with dynamics and "time" links with the time-based elements of rhythm, duration and tempo. This usage of the phrase "the elements of music" links more closely withWebster's New 20th Century Dictionary definition of an element as: "a substance which cannot be divided into a simpler form by known methods"[18] and educational institutions' lists of elements generally align with this definition as well.
Although writers of lists of "rudimentary elements of music" can vary their lists depending on their personal (or institutional) priorities, the perceptual elements of music should consist of an established (or proven) list of discrete elements which can be independently manipulated to achieve an intended musical effect. It seems at this stage that there is still research to be done in this area.
Analysis of styles
while others place less emphasis on certain elements. To give one example, while Bebop-era jazz makes use of very complex chords, including altered dominants and challenging chord progressions, with chords changing two or more times per bar and keys changing several times in a tune, funk places most of its emphasis on rhythm and groove, with entire songs based around avamp on a single chord. While Romantic era classical music from the mid- to late-1800s makes great use of dramatic changes of dynamics, from whispering pianissimo sections to thunderous fortissimo sections, some entire Baroque dance suites for harpsichord from the early 1700s may use a single dynamic. To give another example, while some art music pieces, such as symphonies are very long, some pop songs are just a few minutes long.
Description of elements
Pitch and melody
Pitch is an aspect of a sound that we can hear, reflecting whether one musical sound, note or tone is "higher" or "lower" than another musical sound, note or tone. We can talk about the highness or lowness of pitch in the more general sense, such as the way a listener hears a piercingly high piccolo note orwhistling tone as higher in pitch than a deep thump of a bass drum. We also talk about pitch in the precise sense associated with musical melodies,basslines and chords. Precise pitch can only be determined in sounds that have a frequency that is clear and stable enough to distinguish from noise. For example, it is much easier for listeners to discern the pitch of a single note played on a piano than to try to discern the pitch of a crash cymbal that is struck.
Play (help·info)A melody (also called a "tune") is a series of pitches (notes) sounding in succession (one after the other), often in a rising and falling pattern. The notes of a melody are typically created using pitch systems such as scales or modes. Melodies also often contain notes from the chords used in the song. The melodies in simple folk songs and traditional songs may use only the notes of a single scale, the scale associated with the tonic note or key of a given song. For example, a folk song in the key of C (also referred to as C major) may have a melody that uses only the notes of the C major scale (the individual notes C, D, E, F, G, A, B and C; these are the "white notes" on a piano keyboard. On the other hand, Bebop-era jazz from the 1940s and contemporary music from the 20th and 21st centuries may use melodies with many chromatic notes (i.e., notes in addition to the notes of the major scale; on a piano, a chromatic scale would include all the notes on the keyboard, including the "white notes" and "black notes" and unusual scales, such as the whole tone scale (a whole tone scale in the key of C would contain the notes C, D, E, F♯, G♯ and A♯). A low, deep musical line played by bass instruments such as double bass, electric bass ortuba is called a bassline.
