Suno AI music prompt builder
Suno gives you two inputs that do very different jobs: a Style of Music box and a Lyrics box. The style box is where the sound is decided, and it works best as a short, comma-separated list of tags rather than a flowing sentence. This builder lets you pick a genre, mood, tempo, key, and instrumentation, then assembles them into the tight tag string Suno actually responds to.
How it works
The builder concatenates your selections in the order Suno parses most reliably:
genre/subgenre first, then mood, then tempo and key, then instrumentation, then
production feel. Tempo is emitted as an explicit BPM number plus a feel word,
because Suno reads numeric BPM but interprets groove from adjectives. Key and
scale are optional — they’re useful when you’re matching an existing track, but
over-specifying can make generations stiff. The lyrical theme is kept separate as
a note, reminding you that lyrics belong in Suno’s own lyrics field with
structure tags.
Tips for better Suno generations
- Lead with the strongest genre. “synthwave, retrowave, 80s” reads cleaner than five unrelated genres fighting each other.
- Pair BPM with a feel. “110 bpm, laid-back, swung” beats a bare number.
- Name only 2-3 instruments. Listing every instrument over-constrains the arrangement; pick the ones that define the sound (e.g. analog synth, gated reverb drums).
- Keep lyrics out of the style box. Put them in the lyrics field with
[verse],[chorus],[bridge]tags for clean section transitions.
