Add AI vocals to an instrumental you own: upload the beat, paste your lyrics, describe the voice, and get a song sung over your music.
Drop in the instrumental as an MP3, WAV or FLAC file up to 50 MB, or pick one from your Songluna AI library.
Describe the vocal and the feel in Style, give the song a title, and paste your lyrics with section tags such as [Verse] and [Chorus]. Choose a male or female voice, or leave it on Auto.
Select Add Vocals. Suno V4.5 sings your lyrics over the instrumental for 4 credits, and the finished song appears in your results.
The model writes a vocal melody for your lyrics that fits the tempo, key and sections of your instrumental, sings it in the voice you described, and returns the finished song with vocals, taking your track from instrumental to song in one step. Your original upload is kept unchanged.
| Setting | What to enter |
|---|---|
| Style | The vocal and the feel, up to 1,000 characters: "warm female vocals, airy harmonies, dreamy synth pop, 104 BPM" |
| Title | The song title |
| Lyrics | Your words, with a section tag before each part |
| Vocal gender | Auto, male or female |
If you sang the vocal yourself, you do not need AI vocals: layer your recording over the beat in Songluna AI Studio, free and without an account.
For a cleaner blend, record without reverb at the tempo of the beat, leave some headroom so the vocal never clips, and turn the instrumental down a little where the voice comes in. Need the key of the beat to sing in tune? Find it with the Key & BPM Finder.
The same workspace has an Add Instrumental tab that does the opposite: upload an a cappella or a vocal recording and AI builds the backing track around it.
Upload instrumentals you made, bought with a license that allows this use, or have permission to use, and write or license your own lyrics. Songs you generate follow your plan: personal use on Free, commercial use for eligible music on Plus and Pro. See Commercial Use.
Have a fire instrumental but no vocalist? Upload your beat and get AI-generated vocals that match the energy, key, and vibe of your production.
Quickly hear how different vocal styles sound over your beat before committing to a session singer. Generate multiple vocal takes with different styles and choose the best fit.
Producers can create complete demos with reference vocals to pitch to artists. Show exactly how the final song could sound with vocals over the beat.
Use the workflow when the instrumental already has energy, but the project still needs a hook, chant, guide vocal, or branded line.
Use case example
Hook idea to original sound
Ask for a punchy opening and a timed drop, keep the best version, and cut the video around it rather than reusing a stock loop.
Edit timing
An intro hit, a mid-video drop and an ending to time the edit around.
Use case example
Product brief to jingle
Turn a product page or a short brief into a 15-second jingle while the ad edit is still in progress.
Ad audio
A brand hook with a call-to-action ending; paid plans include commercial use for eligible music.
Use case example
Show concept to intro music
Describe the tone of the show in plain English and get an intro that sounds like the show rather than a template, ready to reuse every episode.
Audio identity
Intro, outro and segment bumper options in the same style.
