AI Backing Track Generator
Turn any song into a backing track to practice and jam over — built from the track's own detected key, tempo and chords. Upload a song, and ChordSonic reads the real progression, then hands it to the track maker — so a guitar backing track in A minor actually comes from a song in A minor. Loop it, slow it down, and practice your part over a band that keeps up.
It takes two steps, not one: the analysis finds the key, tempo and chords, and you tell the track maker what kind of band should play them. Both halves are live today.
Jam along to your own tracks
Analyse a song and send its key, tempo and chord progression straight into the track maker, or start from a blank brief and describe the backing track you want. No card needed to try it.
Upload your song
Drop an MP3 or WAV. ChordSonic detects the key, tempo and full chord progression — the same analysis that already powers the chord finder today.
Backing track built to match
Send that analysis into the track maker: it opens on your song's key, tempo and chords already filled in. Describe the band, and it renders a track built on them. No blank prompt, no guessing.
Practice and play along
Loop a tricky section, slow it down without changing the pitch, and play your part over a band that follows the song. Great for solos, rhythm work and learning by ear.
Backing tracks that come from the song, not a blank prompt.
Most backing tracks force you to hunt for the right key or settle for a generic loop. Because ChordSonic already reads the key, tempo and chord progression from your upload, the backing track inherits all three — a guitar backing track in any key, at the song's real tempo, over its actual changes.
That makes it a natural fit for a practice track to woodshed a solo, a play-along trackto drill your rhythm part, or a jam bed to improvise over. It works from the music you bring, so what you practice over matches what you're trying to learn.
Backing Track Generator FAQ
What is a backing track generator?
It turns a song into a backing track — the full band minus the part you want to play — so you can practice, jam and improvise over it. ChordSonic's version is different from most: instead of starting from a blank prompt, it builds the backing track from the real key, tempo and chord progression it already detected in a song you upload, so the track follows the actual music.
How does it work?
Two steps. Upload a song and ChordSonic reads its key, tempo and chord progression. From the result page you send those numbers straight into the track maker, describe the band you want behind them, and it renders a track built on your song's own key, tempo and chords — one you can loop, slow down and play along to. The musical facts come from your upload, not from a blank prompt.
Can I get a guitar backing track in a specific key?
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.
Who is it for?
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.
Is this the same as cloning the song?
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 that shares that structure, the same way a musician can play along to a song from its chord chart.
Is it automatic?
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 them — an acoustic trio and a synth-pop section are very different tracks over the same progression, and guessing which one you meant is not something we want to do for you.
