You can select notes in the Score Editor and edit them in a variety of ways. When you select individual notes, the Score Editor inspector shows “Notes,” and its controls apply to the selected notes. When no note is selected, the Score Editor inspector shows “Region,” and changes apply to selected regions.
In GarageBand on Mac, do one of the following:
Click the note head.
Select multiple notes by Shift-clicking or by dragging around the notes to enclose them.

You can change the pitch of—or transpose—notes in the Score Editor. This is especially useful when you want to reuse a melody, rhythm part, or other pattern of notes, at a different pitch.

Select notes, then press Option–Up Arrow to raise or Option–Down Arrow to lower the pitch in semitones.

You can delete notes (and pedal markings) in the Score Editor. MIDI controller information, such as pitch bend data, is not deleted, even if you delete the notes the data was recorded with.
