Prompt use
Use "Smooth" in lyrics tags or style instructions to shape the vocal delivery. Section: Vocal Tone Tags.
When to use smooth
Use it near the front of the prompt when smooth should shape the overall feel.
Let it control one clear layer, then add vocal, arrangement, or structure detail around it.
Change only one layer at a time during testing so the results stay learnable.
smooth example prompt
Smooth R&B-pop, relaxed lead vocal, rounded phrasing, warm chorus hook, gentle groove, polished vocal-forward mix
Smooth works best when the singer should sound controlled, rounded, and easy to follow instead of breathy, gritty, or highly processed.
