Separate tone from delivery
Tone describes the sound of the voice: breathy, smooth, gritty, airy, deep, or crisp. Delivery describes how the singer performs: intimate, urgent, relaxed, spoken, or soaring.
Combining one tone word with one delivery word is usually more useful than piling up many vocal adjectives.
Prompt examples
Clear vocal direction
Breathy intimate lead vocal, close-mic verse, soaring chorus harmonies, warm indie pop arrangement, polished vocal-forward mix
The prompt tells Suno how the vocal sounds, how it performs, and where it sits in the mix.
Add range only when it matters
Pitch and range words can be useful, but they should support the song. High-pitched, low-pitched, and mid-range work best when paired with emotion and genre.
For vocal-heavy songs, include whether the chorus should lift, the verse should stay intimate, or harmonies should widen the hook.
Keep lyrics and vocal direction aligned
If the lyric idea is vulnerable, use a vocal direction that supports that feeling. If the lyric idea is triumphant, the performance can be brighter and more open.
