An individually printed song, most often for voice, piano, guitar,or a combination of the three. Any printed music.
Sheet music is a hand-written or printed form of musical notation; like its analogs -- books, pamphlets, etc. -- the medium of sheet music typically is paper (or, in earlier times, parchment). Use of the term “sheet†is intended to differentiate music on paper from a recording, broadcast, or live performance, and more specifically usually refers to the print publication of commercial music alongside the release of a new film, show, record album, or other special event which involves music.
