Music is an art form whose medium is sound and silence. Generally, a song is considered the smallest standalone work of music, especially when involving singing. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities oftimbre and texture. The word derives from Greek μουσική (mousike; “art of the Muses“). In its most general form the activities describing music as an art form include the production of works of music, the criticism of music, the study of the history of music, and the aesthetic dissemination of music.
To many people in many cultures, music is an important part of their way of life. 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. “There is no noise, only sound.”
