There are often many voices (or parts) in a piece of music. In choral music, soprano and alto share the upper staff, and tenor and bass share the lower staff. In keyboard scores (grand staff), the voices may not be quite as clear cut, but there still is typically more than one. A great example of multivoicing occurs in Bach's Preludes and Fugues. There are often as many as four voices occurring at any one time in the piece.
Each staff can have up to 8 different voices. The piano grand staff, however, has a total of eight voices. Four voices in treble clef and four voices in bass clef. You can move your melodies to a different voice line using the voice action.
