From instrumental to vocal song
Give the performance a clear starting point
The backing track, lyrics, voice choice, and style each answer a different part of the request. Keep those inputs specific and easy to understand.
02
Write the words to sing
The lyrics box is for the actual words of the performance. Add verses, a hook, or a complete lyric instead of production instructions.
03
Choose the vocal direction
Leave the voice choice open, or ask for a male or female vocal direction before starting the request.
04
Match the song style
Describe the genre and vocal feel that belong with the instrumental, or use the genre choices as a quick starting point.
05
Compare two vocal takes
The completed request returns two takes. Play both versions and compare how each performance sits against the same backing track.
06
Save or download the result
Completed takes can be played and downloaded from the results area, with the finished songs kept in your MusicWave library.
From backing track to two takes
How Add Vocals works
Choose the backing track
Upload your instrumental or select an eligible instrumental from the MusicWave library.
Add lyrics and style
Paste the words to sing, choose the vocal direction, and describe the genre or performance feel.
Create and compare
Start the request, follow its progress, then listen to the two returned vocal takes.
Before you add vocals
Keep the source and instructions clear
A clean instrumental and well-separated lyrics and style notes make the request easier to judge when both takes return.
Use an instrumental source
The tool is built for backing tracks without an existing lead vocal. A cleaner instrumental leaves more room for the new performance.
Put lyrics in the lyrics box
Write the exact words you want sung. Put genre and delivery notes in the style field so the two inputs do not compete.
Use audio and lyrics you may supply
Upload only music and words you own or have permission to use. Adding a vocal does not change the rights to the source material.
Ways to use it
Try the vocal before you commit to a direction
Test lyrics against a backing track
Hear whether a verse and hook fit the instrumental before arranging another recording session.
Compare two performance directions
Run the same words with a different style or vocal choice when the first delivery does not suit the track.
Finish an instrumental draft
Turn a saved beat or accompaniment into a vocal song you can play, download, and keep working on.
