- Middle C (C4) is the first note to be placed on a ledger line below the treble staff and above the bass staff.
Avoiding Ledger LinesMultiple ledger lines can make sight-reading difficult, so they’re often bypassed in piano music with the following methods:
- 8va, 15ma & Octave Commands
8va means a note or section will be played an octave higher than written; 15ma means two octaves higher:
- The highest note on an 88-key piano is C8 (see image) which is written on the ninth ledger line above the treble staff. Using 15ma above C6 makes this note much easier to identify quickly.
- The lowest note on a standard piano is A0, just under the sixth ledger line below the bass staff; more efficiently, it could be written with 15mb on A2, or 8vb on A1, pictured.
- For Low Treble Notes, Invade the Bass Staff
A note below middle C will always have a place on the bass staff, even if you want to write it as a treble note. B3, for example – the note directly under middle C – rests on top of the bass staff when used as a bass note, but is also ledgered for use as a treble note.
- To differentiate, a treble note written on the bass staff will have an upward-pointing note-stem connected to the middle line on the treble staff.
- A Temporary Clef
You’ll encounter temporary G-clefs on the bass staff, and F-clefs on the treble. This is generally ideal when more than two measures are affected.
