Upload a vocal take, an acapella or a hummed melody and the AI composes a backing track around it. Pick the instruments and mood, and leave out what you do not want.
Preset: tags acoustic guitar, soft drums, warm bass, with negative tags heavy distortion, dubstep. Add a title, edit the tags and upload your vocal.
Songwriters often start with the voice: a recorded melody on a phone, a rough topline, a finished acapella. Turning that into a band arrangement is where projects stall. This page generates the accompaniment for you, building the chords, bass and rhythm around the melody you upload.
The result lets you hear your vocal with real instruments around it in one pass, which is much faster than programming parts by hand to test an idea.
The tags field is your arrangement brief. Name the instruments you want to hear, the genre, and the energy: warm upright bass, brushed drums, soft piano, slow tempo. Specific instrument names pull the result in a clear direction more reliably than abstract mood words.
The negative tags field is the other half: use it to exclude sounds that would fight the vocal, such as heavy distortion, aggressive synth leads or sub-bass drops. Both fields accept up to 500 characters.
Because the model has to work out the melody from your audio, a clean recording matters. Sing close to the microphone in a quiet room, keep reverb off, and avoid background music. A steady tempo helps the generated rhythm lock onto the phrasing.
If the first result misses the feel, vary the tags first and the upload second. A calmer take with clearer pitch tends to improve the harmony the model chooses beneath it.
The page accepts a normal audio upload, so it does not need a track generated earlier on the site. The model infers harmony from the melody you sing, so pitchy or very reverberant takes can lead to unexpected chords. Title, style tags and negative tags are all required. Results vary between runs, so generate a few versions at 9 credits each and compare them. A clean, dry source recorded close to the microphone gives the model the clearest pitch to follow, which in turn produces more sensible chord choices.

Typical reasons to generate an accompaniment.
Hear a voice memo with a full arrangement behind it.
Test a topline against several styles without producing each one.
Build a backing track for audition clips and covers of your own songs.
Create simple accompaniment beneath a practice recording.
Upload, set the style, generate.
Add one audio file of a dry vocal, an acapella or a melody line.
A dry take with little reverb gives the model a clearer melody
Give a title and style tags such as instruments and mood. The page starts with acoustic guitar, soft drums and warm bass, plus exclusions.
Name instruments, not just a genre
One run costs 9 credits. Set a vocal gender preference if relevant and try other tags for variations.
Change the tags, not the upload, to compare arrangements
