About TuneLabs
TuneLabs is a free online music generator. Pick a genre, key and
scale, hit Generate, and it composes a looping arrangement — melody, chord
progression, bassline and drum beat — instantly in your browser. Nudge the tempo,
note density, swing and reverb, remix each part with its own seed, then export
your track as WAV or MIDI or copy a share link that reproduces it exactly.
Unlike AI music tools, TuneLabs composes with music theory: seeded algorithms
choose from ~90 scales and a library of chord progressions, so every track stays
in key and the same seed always plays the same song. There is no server, no
account and no upload — all audio is synthesized locally with the Web Audio API,
so it even works offline. Use it as a melody generator, a
chord progression generator, a beat-making sketchpad, or a
starting point for your next production — the MIDI export drops straight into
any DAW.
Frequently asked questions
Is TuneLabs free to use?
Yes. TuneLabs is completely free — no account, no signup and no download. Everything runs in your browser.
Can I download the music I generate?
Yes. You can export any track as a WAV audio file, a MIDI file for your DAW, or record a loop as it plays.
Does TuneLabs use AI?
No. TuneLabs composes with music theory — seeded algorithms pick scales, chord progressions and rhythms, so the same seed always reproduces the same track. Nothing is sent to a server.
What genres and scales does it support?
19 genre presets: Lofi, Chill, Happy Pop, Sad, Cinematic, Soundtrack, House, Synthwave, Jazz, Funk, Ambient, Bollywood, Arabic, Latin/Reggaeton, Flamenco, K-Pop, Afrobeat, East Asian and Reggae — plus every key and around 90 scales, from major and minor to pentatonics, blues, Indian ragas and world scales. Bollywood and Soundtrack come with a full ensemble: counter-melody, tabla-style percussion, tanpura drone and film-song structure.
Does it work offline?
Yes. After the page loads, all audio is synthesized locally with the Web Audio API, so generation and playback keep working without a connection.
