Writing to a fixed instrumental
Got a beat from a producer? Write the words and hear a sung topline over it straight away.
When the music is fixed, the topline has to fit its chords, tempo and sections. Hearing a sung draft quickly shows whether your lyric has too many syllables for the groove or a chorus that sits too low.
The result also works as a guide vocal: send it with the beat so the artist hears the intended melody.
Topliners often receive instrumentals with a deadline. Add Vocal lets you put a lyric over the beat and hear it sung, so you can judge melody and phrasing before booking a singer.
Paste your lyrics or describe the theme, set the vocal direction, and SeedSong AI builds a vocal line that follows the music you provided.

Leave space

Mark the chorus
Label sections so the hook lands where the music lifts.
Add Vocal questions
Do I need to write lyrics first?
No, but your own lyrics give you the most control. You can also describe a theme.
Can I get the vocal on its own afterwards?
Yes. Run the result through the vocal remover to separate the new vocal.

Beats with a steady tempo and clear section changes give the vocal the best structure.
