Describe it. Hear it.
Write a prompt in plain language — "warm acoustic folk for a sunrise montage" — and Harmonai composes melody, chords, rhythm, and instrumentation into a complete, structured track. No music theory, no MIDI editing.
- Natural-language prompts
- Full-length arrangements
- Multiple variations
40+ styles, one tap away
Swing from lo-fi study beats to soaring trailer cues without rewriting your prompt. Layer a mood — energetic, melancholic, hopeful — on top of any genre and Harmonai adjusts the entire arrangement to match.

- Cinematic
- Pop
- Electronic
- Ambient
- Hip-hop
