Harmony Grid: A Browser Instrument You Can See

Field notes

The instrument maps musical relationships onto a playable note grid: users select a chord and mode, move the root, and use visual markings to see sounding notes and filtered possibilities. The page also describes synthesized or sampled voices, keyboard and clavier control, sustain, drones, a metronome, and adjustable grid intervals. It says instrument configurations can be saved as files and that MIDI input and output work where browser support permits.
