Tempo: the number and the feel

Country sits roughly between 80 and 120 BPM. Ballads 60–82, classic 90–120, modern radio country 100–125, country rock 118–145, bluegrass 135–180.

Feels slow even though the number is high? Then it is the subdivision, not the tempo. Left alone, Suno fills in a calm backbeat — a clap on two and four and little else. A train beat with running eighths at 110 sounds faster than a half-time arrangement at 130.

Three things that raise the felt tempo without touching the number: choose a rhythmic feel (train beat, two-step, double-time), put more syllables in a line, and write shorter lines that chase each other. If the melody sings in whole notes, any tempo drags.

Order matters

Suno weighs the earliest terms in the style field more heavily. Put genre and tempo first, production and exclusions last. This app builds the sentence in that order.

How many tags

Advice varies: some testers keep to 4–7, others 6–12. What everyone agrees on is the failure at either end — below 4, Suno fills the gaps with its own default taste; above 12, tags contradict each other and you get a compromise on all fronts. This app warns outside 4–10.

Four things that fail silently

• Artist names are unreliable and are sometimes filtered.
• Mixing jargon (sidechain, -3dB) is not understood.
• BPM is guidance, not a metronome — and does not belong in brackets in the style field.
• Negative phrasing in the style field works only partly; no drums and no vocals are reliable, vaguer negatives are not.

Tags in the lyrics

• Each tag on its own line, directly above the section. Capitalisation does not matter.
• Stacking is allowed: [Chorus] [Belted]. But six or more on one line will collide.
• Do not invent your own tags — only established ones are recognised.
• Round brackets get sung, square brackets do not.

Sliders

Style Influence decides how literally your style field is taken. High only works when that field is lean and precise; a vague prompt on strict mostly produces noise.

Weirdness is how far the generation may stray from genre norms. For songs you intend to keep, stay below roughly 50–60%. There is no universally correct number — change one thing at a time and compare.

When something does not work

Take the element out via Exclude and put something in Styles that fills the role it left behind. Exclude: guitar is weak; Exclude: guitar plus Styles: piano-led is strong. Then change one variable per attempt, or you will not know what helped.
