The Vocal Chord app for iPhone and iPad

The Vocal Chord helps a cappella singers get that excellently harmonious starting chord. You compose the chord on a musical staff, and when you need it, it plays the arpeggio in the correct tempo. It keeps a library of your pieces by name, and you can even build them into performance programs.
