From Wikipedia, the free encyclopedia
The Grand Staff using both bass clef on the bottom and treble clef on top allows for four octaves of notation, counting the two high ledger lines for Soprano C and two ledger lines below bass clef for Deep C. Note, however, that more than two ledger lines may be used.
About the Grand Staff
It is known as the grand staff because the two clef notation allows the notation of nearly all musical notes without many ledger lines or octave shifts such as 8va or 8vb. The grand staff shows that the treble clef and bass clef are used together by using a brace.
Middle C (on the grand staff) is named so because it appears exactly in the middle between the bass and treble clefs. Middle C is not exactly in the middle of any keyboard instrument, including the piano. Nearly all keyboard music is written on the grand staff, as is some choral music.
