Definition: A grand staff is a system of two or more staves written for one instrument, to be played by one performer:

  • The piano’s grand staff is a two-part staff, consisting of the treble staff on top and the bass staff on the bottom. These staves are connected by a brace, and by barlines throughout the music.
  • Organ music uses a three-part grand staff. Its treble and bass staves share braces and barlines, while the lowest staff – a bass staff used for foot-pedal notation – is only connected to the other staves by the very first barline before its clef.
