What Is Music ???

Music is an art form whose medium is sound and silence. Its common elements are pitch (which governs melody and harmony), rhytm (and its associated concepts tempo, meter and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek (mousike; "art of the Muses").

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 aleatory forms. Music can be divided into genres and sub genres, 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, aline 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. Music may be played and heard live, may be part of a dramatic music 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 Philosepers 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." Musicologist Jean-Jacuez 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.
