Add an instrumental to your vocal
Add instrumental builds a backing track around a vocal or melody you already have. Upload an a cappella you own or pick a track from your library, describe the accompaniment, and AI Song Generator returns versions with music arranged around your performance.

How it works
Choose the vocal
Upload a vocal you own or select a library track, and confirm your rights to it.
Describe the backing
Genre, instruments and density, plus anything to exclude.
Generate
Compare how each returned version supports the vocal.
Finish
Split stems, extend or export the version you keep.
What to upload
The backing is built around what you give it, so the cleaner the source, the tighter the result. Tracks already in your library can be used as the source too.
- A dry a cappella: just the voice, with little reverb
- A clean take with no background noise or other instruments
- A performance with a steady tempo, so the backing has something to lock to
- A recording you own or are authorized to use
Describing the accompaniment
The accompaniment description is required. Name the genre, the core instruments and how busy the backing should be. "Sparse acoustic guitar and brushed drums, lots of space" keeps the voice in front; "full band, big drums" turns it into a produced track. Use exclude styles to rule things out, such as "no synths" or "no trap hats".
Timing and feel
The backing follows the performance you supply, so a steady, confident take produces a tighter result. If the vocal drifts in tempo, expect a looser accompaniment. Try more than one version: the same vocal can be read in quite different ways, and the second interpretation is sometimes the one that fits.
Common uses
A finished vocal with no music behind it is a common starting point:
- Turn a rap verse recorded over nothing into a full track
- Give a singer-songwriter's a cappella demo a band arrangement
- Try the same vocal in several genres to find the right production
- Build a backing for a melody you sang into your phone in a quiet room
After the backing is built
The result is saved to your library as a new recording, and your source stays as it was. Split it into stems to rebalance the vocal against the music, extend it for an outro, or export WAV to mix it elsewhere.
