Using the iPad in the music class

I have been a little slow lately.  I feel I am underutilizing the equipment.  Here are some of the ways we have used the iPads lately:

1. Used Garageband to play the ostinato from Bach's Passacaglia and Fugue in C minor along with recording in music theory class.
2. Created iMovie trailers using our new iPad2s.
3. Choir used iPads to listen to different versions from youTube of the 24 Italian Songs.
4. Played Dustbuster in Choir.
5. Played chords from "I'm Yours" using Six Strings.
