AI Backing Track Generator

It gives you a backing track — a band to play over — so you can practice, jam and improvise. ChordSonic's version is different from most: instead of starting from a blank prompt, it starts from the key, tempo and chord progression it already detected in a song you upload. The key and tempo are set exactly; the progression rides inside the brief as an aim — usually landed, never promised.

Two steps. Upload a song and ChordSonic reads its key, tempo and chord progression. From the result page you send them straight into the track maker, describe the band you want, and it renders a new track in your song's key and at its tempo — one you can loop, slow down and play along to. The chord progression travels with the brief as something to aim for: it usually lands, but it is not guaranteed.

That's the whole idea. The backing track carries the key and tempo detected in your upload, so a guitar backing track in A minor at 120 BPM comes straight from a song that's actually in A minor at 120 BPM. Loop a section and slow it down to work on your solo or rhythm part.

Anyone who practices over a track: guitarists, bassists and keyboard players working on solos and improvisation, students learning a song's chords, and songwriters who want a play-along bed to try ideas over. If you've ever searched YouTube for a backing track in the right key, this builds one from the song itself.

No. It doesn't copy or reproduce the original recording. It reads musical facts — the key, the tempo, the chord progression — and generates a new backing track from them, the way a band reads a chord chart before playing its own version.

Not in one click, and deliberately so. The analysis hands your key, tempo and chords to the track maker; you still say what kind of band should play — an acoustic trio and a synth-pop section are very different tracks in the same key, and guessing which one you meant is not something we want to do for you.
