Color helper. Shows each note on the staff in its rainbow color, so beginners can match it to the colored buttons. Turn it off once she's reading on her own. Exact key only. Off: any C on the piano counts as C. On: she has to play the exact key shown.

Microphone tip: put the iPad on the music stand, keep the room quiet, and press each key firmly. The green bar shows that it can hear the piano.
