Suggest using the AUPitch effect. Piano and Guitar would work well (I suppose) with the Complex or Percussive presets to start with.

"Like the Track Editor’s Pitch slider, AUPitch lets you raise the overall pitch of a track up or down. But unlike Pitch, AUPitch has a few different parameters to help reduce artifacts and produce natural sounding tone. Your success using any of these controls will depend on your source material, but here are a few guidelines:
Maximum Render Quality is not necessarily best. In some cases I’ve had best results with Medium.
100 Cents is a half step, and 1200 Cents is one octave.
Effects Blend, if not at 100, will mix the original sound with the pitch-shifted sound.
Turn Smoothness up to remove certain kinds of artifacts.
Turn Tightness down to remove other kinds of artifacts, but at the expense of losing some depth; if it sounds too “thin,” bring it back up."
