A staff of written music generally begins with a clef, which indicates the pitch-range of the staff. The treble clef or G clef was originally a letter G and it identifies the second line up on the five line staff as the note G above middle C. The bass clef or F clef identifies the second line down as the note F below middle C. While the treble and bass clef are the most widely used, other clefs, which identify middle C, are used for some instruments, such as the alto clef (for viola and alto trombone) and the tenor clef (used for some cello, bassoon, tenor trombone, and double bass music). Some instruments use mainly one clef, such as violin and flute which use treble clef, and double bass and tuba which use bass clef. Some instruments, such as piano and pipe organ, regularly use both treble and bass clefs.
