# SuperTime Ultra

> Browser-based rhythm, harmony, and gesture instruments for musicians, students, and curious players.

SuperTime Ultra is a web music practice suite. It includes a precise metronome, polyrhythm tools, harmony references, training tools, and Motion, a camera instrument controlled primarily by hand gestures.

## Motion

- [Motion](https://supertimeultra.com/motion): Play chords, Air Melody, beats, synth sounds, and local performances with two-handed tracking.
- [Gesture Synth Online](https://supertimeultra.com/tools/gesture-synth): Play chords, melodies, beats, and synth with simple hand movements using camera-based hand tracking in a free browser instrument.
- [Online Theremin](https://supertimeultra.com/online-theremin): Hold a chord with one hand and raise or lower the other through a musical scale to play a theremin-like lead.
- [Webcam Music Instrument](https://supertimeultra.com/webcam-music-instrument): Turn a webcam into a playable musical instrument controlled by your hands.
- [Play Music with Hand Gestures](https://supertimeultra.com/play-music-with-hand-gestures): Learn the basic gesture-to-chord, gesture-to-melody, and sound-shaping workflow.
- [Beat Challenge](https://supertimeultra.com/beat-challenge): Practice an I–V–IV–V chord loop against a shared beat with separate target and timing feedback.
- [Chord Rhythm Practice](https://supertimeultra.com/chord-rhythm-practice): Land camera-tracked chord changes on the beat, with optional on-stage touch and keyboard assistance.

## How Motion works

- Chords mode maps deliberate hand shapes to stable chord changes.
- Air Melody maps the melody hand's height to notes in the selected key and scale.
- One hand holds the chord bed while the melody hand raises or lowers; Chords mode adds filter and Air Dock control.
- Beat triggers stay visible: use Play beat in the hero, live stage, or Sound settings, press B, or point at Beat in Air Dock.
- Camera play requires an HTTPS browser and camera permission.
- Touch chord pads and keyboard controls can be used from the Play without camera entry. Air Melody also offers a vertical ribbon, Space, and Up/Down keys; Left/Right remain accepted as aliases.
- Cover Studio records only after the player explicitly starts a local take.
