Give the hook one repeatable phrase
Suno responds better when the hook has one clear chorus phrase that can survive repetition. Keep the line short enough to sing, then let the surrounding lyrics explain or reframe it.
Instead of asking for catchy lyrics in general, specify the hook behavior: repeated chorus phrase, call-and-response tag, final-line payoff, or short refrain that returns after the bridge.
Prompt examples
Hook-led chorus prompt
Atmospheric pop, intimate verse vocal, repeated chorus hook phrase, varied repetition after the bridge, smooth final chorus, polished modern mix
The hook is stable, while the surrounding lyric context changes enough to keep the repeat useful.
Use repetition with controlled variation
A hook can become flat if every return is identical. Ask for a repeated phrase with small lyric variation in the second chorus or final chorus.
This is especially useful when the song has a bridge. The bridge can reveal a new angle, then the hook returns with more emotional weight.
Connect the hook to arrangement energy
Hook lyrics work best when the arrangement knows where the payoff lives. Pair hook instructions with chorus lift, build-up dynamics, or emotional climax language.
If the hook should feel intimate, use smaller words like close vocal, warm harmony, or stripped final refrain. If it should feel big, use wide chorus, layered vocals, or final chorus expansion.
