How to Write Suno Prompts That Work: Style, Tags & Structure

If your Suno tracks keep coming out generic, the problem is almost never your idea — it is that you are putting everything into one box. Suno Custom Mode gives you three separate fields: Style of Music, Lyrics, and Exclude Styles. Each does a different job, and Suno treats them differently. Get the split right and the model stops guessing. The fastest way to get all three fields formatted correctly is our free Suno Prompt Builder — pick a genre, mood, and structure, and it composes copy-ready fields for you. But the method matters more than the tool, so here it is.

The three fields, and what belongs in each

The single most common mistake is writing stage directions into the Lyrics field. Suno sings anything in the Lyrics field that is not a valid bracketed tag. Type "(guitar solo here)" and Suno may literally sing the words "guitar solo here." Type "energetic and upbeat" hoping to set the mood, and it becomes a lyric.

So split your intent cleanly. Sung words go in Lyrics. Genre, instruments, tempo, vocal tone, and production texture go in Style of Music. Traits you want to avoid go in Exclude Styles. Everything else — your reasoning, your BPM target, your "make it sound like early 2010s indie" note-to-self — stays out of Suno entirely.

Style of Music: the 4-7 descriptor formula

The reliable sweet spot is four to seven meaningful descriptors. Fewer than four and Suno fills the gaps with generic defaults. More than seven and the ideas start fighting each other — you asked for "dreamy" and "aggressive" and "minimal" and "orchestral," and the model splits the difference into mush.

Order them like this: primary genre, subgenre or mood, tempo/energy, key instruments, vocal tone, production texture, dynamic arc. A worked example:

124 BPM deep house, nocturnal and hopeful, mid-tempo groove, warm pads and analog synth bass, airy intimate vocal, polished modern mix, opens wide on the final chorus

That is seven descriptors, each pinning down one axis. Lead with the dominant genre unless controlling the vocal matters more — in which case put the voice first: Warm baritone, close and conversational. Indie folk rock, mid-tempo acoustic guitar and soft organ, dry intimate production. BPM is a hint, not a guarantee, but adding it helps for genres with a strong tempo identity (house at 124, dubstep at 140, liquid drum and bass at 174). Keep genre fusion to two or three genres at most.
