Chapter 7 Tutorial 5: Working with Music Notation 59
Adding Pedal Symbols
Music notation for piano and some other instruments includes symbols for the sustain
pedal. When the sustain pedal is down, the instrument sustains all notes until the pedal
is released (up). You can add pedal down and pedal up symbols, which control whether
the notes are sustained in GarageBand.
To add pedal down and up symbols:
1 Click the Note Value button and choose the pedal symbol from the menu.
2 Hold down the Command key and place the pointer in the editor at the point where
you want the pedal down marker.
3 Press the mouse button.
The pedal down symbol appears at the current position of the pointer. If you release
the mouse button, the pedal up symbol is placed shortly after the pedal down symbol.
4 Without releasing the mouse button, drag to the point where you want the pedal up
marker.
5 Release the mouse button.
The pedal up symbol appears at the current position of the pointer.
To move the pedal up symbol:
1 Click the pedal symbol to select it.
The pedal down and pedal up symbols become green, indicating that they are
selected.
2 Drag the pedal up symbol to its new position, then release the mouse button.
