Long description

This figure contains two images. The first shows the keys of a keyboard (two octaves, from C to C, as in Figure 1). The second shows the corresponding notes on a pair of staves joined by a bracket in the left-hand margin (the grand staff). There are eight notes on the lower staff, ascending from one C to another C (identified as ‘middle C’) an octave above it. There are also eight notes in the upper staff, ascending from a C identified as ‘middle C’ to another C an octave above it. The top staff is labelled ‘treble staff’ and begins with a treble clef symbol. The bottom staff is labelled ‘bass staff’ and begins with a bass clef symbol. As noted, a bracket joins the two staves. Middle C is labelled on both staves where it appears, as are the ledger lines used to notate it.
