  • Rotate your handtone / brightness
  • Tap thumb to MIDDLE finger → 👊 kick drum
  • Tap thumb to RING finger → 🥁 snare drum
  • Pick the voice (Strings / Guitar / Bass / Lead / Bells) in the toolbar.

HS2 · Duet Hands EXPERIMENTAL

HS2 — a two-handed duet

  • 🫱 Right hand = melody. Raise / lower your hand to change pitch (snapped to the key). Pinch thumb + index together for louder. Rotate the hand for a brighter or darker tone.
  • 🫲 Left hand = chords. Raise / lower to move through the chords of the key. Open your hand to swell the chord; make a fist to mute it.
  • 🎶 Both hands share one key & scale, so the melody always fits the chords.
  • 📸 Best strapped to your chest with the rear camera facing your hands. Use Swap hands if the roles feel reversed.
