Music is an art form consisting of sound and silence expressed through time. Elements of sound as used 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. For purposes of discussion and exploration of the topic, music is 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. Music may also involve 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, ceremonial or religious purposes and by many composers purely as an academic instrument for study.
