Music is an art form whose medium is sound and silence. Its common elements are pitch, rhythm, dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (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 aleatoric forms.
