The Complete Definition Of The Music
Music is a form of art that involves organized and audible sounds and silence. It is normally expressed in terms of pitch (which includes melody and harmony), rhythm (which includes tempo and meter), and the quality of sound (which includes timbre, articulation, dynamics, and texture). Music may also involve complex generative forms in time through the construction of patterns and combinations of natural stimuli, principally sound. Music may be used for artistic or aesthetic, communicative, entertainment, or ceremonial purposes. The definition of what constitutes music varies according to culture and social context.
If painting can be viewed as a visual art form, music can be viewed as an auditory art form.

The broadest definition of music is organized sound. There are observable patterns to what is broadly labeled music, and while there are understandable cultural variations, the properties of music are the properties of sound as perceived and processed by humans and animals (birds and insects also make music).
Music is formulated or organized sound. Although it cannot contain emotions, it is sometimes designed to manipulate and transform the emotion of the listener/listeners. Music created for movies is a good example of its use to manipulate emotions.
Greek philosophers and medieval theorists defined music as tones ordered horizontally as melodies, and vertically as harmonies. Music theory, within this realm, is studied with the pre-supposition that music is orderly and often pleasant to hear. However, in the 20th century, composers challenged the notion that music had to be pleasant by creating music that explored harsher, darker timbres. The existence of some modern-day genres such as grindcore and noise music, which enjoy an extensive underground following, indicate that even the crudest noises can be considered music if the listener is so inclined.
20th century composer John Cage disagreed with the notion that music must consist of pleasant, discernible melodies, and he challenged the notion that it can communicate anything. Instead, he argued that any sounds we can hear can be music, saying, for example, “There is no noise, only sound,”. According to musicologist Jean-Jacques Nattiez (1990 p.47-8,55): “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.”
Johann Wolfgang Goethe believed that patterns and forms were the basis of music; he stated that “architecture is frozen music.”

The history of music predates the written word and is tied to the development of each unique human culture. Although the earliest records of musical expression are to be found in the Sama Veda of India and in 4,000 year old cuneiform from Ur, most of our written records and studies deal with the history of music in Western civilization. This includes musical periods such as medieval, renaissance, baroque, classical, romantic, and 20th century era music. The history of music in other cultures has also been documented to some degree, and the knowledge of “world music” (or the field of “ethnomusicology”) has become more and more sought after in academic circles. This includes the documented classical traditions of Asian countries outside the influence of western Europe, as well as the folk or indigenous music of various other cultures. (The term world music has been applied to a wide range of music made outside of Europe and European influence, although its initial application, in the context of the World Music Program at Wesleyan University, was as a term including all possible music genres, including European traditions. In academic circles, the original term for the study of world music, “comparative musicology”, was replaced in the middle of the twentieth century by “ethnomusicology”, which is still considered an unsatisfactory coinage by some.)
Popular styles of music varied widely from culture to culture, and from period to period. Different cultures emphasised different instruments, or techniques, or uses for music. Music has been used not only for entertainment, for ceremonies, and for practical & artistic communication, but also extensively for propaganda.
As world cultures have come into greater contact, their indigenous musical styles have often merged into new styles. For example, the United States bluegrass style contains elements from Anglo-Irish, Scottish, Irish, German and some African-American instrumental and vocal traditions, which were able to fuse in the US’ multi-ethnic “melting pot” society.
There is a host of music classifications, many of which are caught up in the argument over the definition of music. Among the largest of these is the division between classical music (or “art” music), and popular music (or commercial music – including rock and roll, country music, and pop music). Some genres don’t fit neatly into one of these “big two” classifications, (such as folk music, world music, or jazz music).
Genres of music are determined as much by tradition and presentation as by the actual music. While most classical music is acoustic and meant to be performed by individuals or groups, many works described as “classical” include samples or tape, or are mechanical. Some works, like Gershwin’s Rhapsody in Blue, are claimed by both jazz and classical music. Many current music festivals celebrate a particular musical genre.
There is often disagreement over what constitutes “real” music: late-period Beethoven string quartets, Stravinsky ballet scores, serialism, bebop-era Jazz, rap, punk rock, and electronica have all been considered non-music by some critics when they were first introduced.
 Aspects as seen by [http://www.FaceYourArt.com]
Main article: Aspects of music
The traditional or classical European aspects of music often listed are those elements given primacy in European-influenced classical music: melody, harmony, rhythm, tone color or timbre, and form. A more comprehensive list is given by stating the aspects of sound: pitch, timbre, loudness, and duration. These aspects combine to create secondary aspects including structure, texture and style. Other commonly included aspects include the spatial location or the movement in space of sounds, gesture, and dance. Silence has long been considered an aspect of music, ranging from the dramatic pauses in Romantic-era symphonies to the avant-garde use of silence as an artistic statement in 20th century works such as John Cage’s 4’33.”John Cage considers duration the primary aspect of music because it is the only aspect common to both “sound” and “silence.”
As mentioned above, not only do the aspects included as music vary, their importance varies. For instance, melody and harmony are often considered to be given more importance in classical music at the expense of rhythm and timbre. It is often debated whether there are aspects of music that are universal. The debate often hinges on definitions. For instance, the fairly common assertion that “tonality” is universal to all music requires an expansive definition of tonality.
A pulse is sometimes taken as a universal, yet there exist solo vocal and instrumental genres with free, improvisational rhythms with no regular pulse; one example is the alap section of a Hindustani music performance. According to Dane Harwood, “We must ask whether a cross-cultural musical universal is to be found in the music itself (either its structure or function) or the way in which music is made. By ‘music-making,’ I intend not only actual performance but also how music is heard, understood, even learned.” 
Main article: Music industry
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 attempt to derive their income from music. Professional musicians are employed by a range of institutions and organizations, including armed forces, churches and synagogues, symphony orchestras, broadcasting or film production companies, and music schools. As well, professional musicians work as freelancers, seeking contracts and engagements in a variety of settings.
Although amateur musicians differ from professional musicians in that amateur musicians have a non-musical source of income, 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 rare 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).
Main article: Performance
Chinese Naxi musicians
Someone who performs, composes, or conducts music is a musician. Musicians perform music for a variety of reasons. Some artists express their feelings in music. Performing music is an enjoyable activity for amateur and professional musicians, and it is often done for the benefit of an audience, who is deriving some aesthetic, social, religious, or ceremonial value from the performance. Part of the motivation for professional performers is that they derive their income from making music. Not only is it an income derived motivation, music has become a part of life as well as society. Allowing one to be motivated through self intrinsic motivations as well, as a saying goes “for the love of music.” As well, music is performed in the context of practicing, as a way of developing musical skills.
 Solo and ensemble
Many cultures include strong traditions of solo or soloistic 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 organized performance rituals such as the modern classical concert or religious processions.
Chamber music, which is music for a small ensemble with no more than one of each type of instrument, is often seen as more intimate than symphonic works. A performer is called a musician or singer, and they may be part of a musical ensemble such as a rock band or symphony orchestra.
 Oral tradition and notation
Main article: Musical notation
Music is often preserved in memory and performance only, 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 which demand improvisation or modification to the music. In the Gambia, West Africa, the history of the country is passed aurally through song.
