For Seniors: Use GarageBand on iPad 2
Tap on an instrument, such as Keyboard, to display it.
A series of buttons appear at the top of the window that allow you to record what you play on the virtual instrument, play it back, visit any songs you have saved, control volume, and return to the main instrument selection screen.
Tap the instrument, whether it’s a drum or keyboard, to produce sounds. Tapping the Instruments button allows you to change to a different instrument.
