DETAILS OF MUSIC
Music is an art form consisting of sound and silence expressed through time. Elements of sound in music are pitch (including melody and harmony), rhythm (including tempo and meter), structure, and sonic qualities of timbre, articulation, dynamics, and texture. The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions and performances to improvisational or aleatoric forms. Music can be divided into genres and sub-genres, although the dividing lines and relationships between music genres are often unclear and/or controversial. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form.
