Harmony: second and third voice, instantly

Compose a melody by playing, singing, or importing audio, and generate simultaneous diatonic 2nd and 3rd voices in the detected key (or guided by a chord). Transpose, listen to each combination, and export everything to MIDI.

What this tool does

  • Detects your melody's key (major/minor) with a tonal-profile model.
  • Generates a diatonic second or third voice, fit to the voice range you pick.
  • Plays melody and harmony together so you can hear both voices.

Record with the microphone, import audio, or play the keyboard; save and sync your projects.
