ChordMelo generates melodies, drums and basslines from a chord progression and lets you take them away as MIDI, for free. It does not produce finished tracks. The point is to hand you something to edit in your DAW before the blank page becomes a problem.
Three tools and a series
- ChordMelo — three vocal melodies or guitar leads over your chord progression.
- BeatMelo — three drum grooves in eight styles, with per-part regeneration.
- BassMelo — three basslines from your chords and a style.
- Music theory from zero — a 33-part series you can listen to as you read.
How it is built
- Free, no account, no limit on how many times you generate.
- Everything runs in your browser. Your chord progressions and settings are never sent to a server.
- It is not generative AI. There is no trained model and no training data — candidates are built from music theory and per-style rules, then scored.
- The output is MIDI, so the sounds stay your choice.
- The same settings and the same seed always give the same result.
What you may do with the output
The melodies and MIDI files are yours to use, commercially or otherwise, with no credit required. Coincidental similarity to existing music can never be ruled out, so check before you release or sell.
