## What is Index Theremin?

Theremin is a tiny instrument you play with thin air.

Hold up one finger in front of your phone: raise it for higher notes, move it sideways to play louder. That's it, you're playing. Make a fist to stop.

A SOUND FOR EVERY MOOD
• Theremin: the classic eerie wail
• Dusk: a dark, slow, melancholic synth
• Aura: an airy, voice-like pad
• Glass: a soft, bell-like shimmer
• 8-Bit: a video-game square wave

ALWAYS IN TUNE
Auto-Tune snaps you to a scale (major, minor, pentatonic or every note) in any key. Hard for the robot effect, Smooth for a gentle glide.

PLAY A DUET
Turn on Duet Mode and each hand becomes its own instrument, with its own sound and settings.

MORE TO PLAY WITH
• Reverb and Pulse effects
• Volume and octave for each hand
• Make a fist to mute without hiding your hand
• Portrait or landscape, iPhone and iPad

PRIVATE BY DESIGN
Hand tracking happens entirely on your device. Nothing is recorded, uploaded or collected.
