Clef Change
A mid-staff change of clef that keeps notes in the staff and cuts ledger lines
Related
A clef change replaces the clef in the middle of a staff so that the range stays inside the five lines. It is common in cello, bassoon, trombone and vocal music.
The new clef is placed before the note where it takes effect, usually after a barline or at a phrase break. If the range returns, the old clef may be restored, or ledger lines may carry the passage instead.
A clef change alters how the staff is read, not the pitch. The player reads the same lines and spaces under a new sign; it often works with ledger lines and octave signs, but none of the three replaces another.
