Prompt use
Use "Deep" in lyrics tags or style instructions to shape the vocal delivery. Section: Vocal Tone Tags.
When to use deep
Use it near the front of the prompt when deep 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.
deep example prompt
Deep lead vocal, dark electronic pulse, robotic backing accents, dramatic low-end pressure, polished cinematic chorus
Deep gives the vocal more weight and authority when the song needs lower-register contrast or darker presence.
