AI music prompt guides for seven platforms

Last checked 4 October 2026

Every AI music generator reads a prompt differently. Suno has separate boxes for the style, what to exclude and the lyrics; Stable Audio 3 makes instrumentals and wants a track-type prefix; Eleven Music can follow a plan with a length for every section. These guides set out what each of seven platforms reads, with the page each fact came from and the date it was checked.

There is one guide for each platform (Suno, Eleven Music, Lyria 3.5, Stable Audio 3, EasyMusic, Loudly and Udio), and a page that compares them side by side. Every guide writes the same song for its platform, so the differences are easy to see.

SunoThe Style, Exclude Styles and Lyrics boxes, section tags, and the three v6 models. Eleven MusicComposition plans, include and exclude styles, section lengths and lyrics. Lyria 3.5Genre first, named instruments, BPM and key, timestamped sections and lyrics. Stable Audio 3The track-type prefix, genre first, instrumentals only, and length as a setting. EasyMusicThe Style brief, Exclude styles, section cues after an em dash, and target duration. LoudlyText to Music's prompt, its VEGA and MANTA 1 models, lyrics for MANTA 1, and releasing. UdioThe prompt, Style Reduction, Udio's lyric tags, and its download rules today.All seven comparedPrompt limits, exclusions, lyrics and song length for all seven, and one brief written for each.

How were these guides made?

APMonster keeps a file describing each platform: the form its prompt takes, how it takes things to avoid, how it reads a song's structure, and how long APMonster keeps its prompts. The app writes every prompt from that file, and these pages are built from the same file, so a fact that changes in the app changes here at the next build.

Where a platform documents a rule or a limit, the guide names the page it came from and the date it was read. Where a platform documents nothing, the guide says so and gives APMonster's own practice, marked as such. Where a platform's own advice differs from APMonster's practice, the guide gives both.

APMonster is not affiliated with any of these platforms. Their rules change without notice, so each guide shows when its facts were last checked.

Which platforms sing, and which make instrumentals?

Suno, Eleven Music, Lyria 3.5, EasyMusic and Udio sing lyrics, written with section tags or, on Eleven Music, a plan. Stable Audio 3 makes instrumentals only. Loudly's VEGA models make instrumentals, and its MANTA 1 model sings. For Stable Audio 3 and Loudly's VEGA models, APMonster's lyric writer produces a vocal guide a singer can perform over the track instead of lyrics; for MANTA 1 it writes sung lyrics.

Frequently asked questions

Why does each AI music generator need a different prompt?

Each one reads a prompt its own way. Some take a style in short tags, some take sentences, one takes a plan with a length for every section, and one takes a track-type prefix and makes no vocals. A prompt written for one platform loses detail, or gets ignored, on another.

How often are the guides checked?

Each guide shows the date its facts were last checked against the platform's own pages. The platforms change their rules without notice, so the guides are re-checked every month.

Is APMonster affiliated with these platforms?

No. APMonster is an independent tool that writes prompts and lyrics for them. The platforms' names belong to their owners.

Can APMonster write a prompt for every platform at once?

Yes. In APMonster's Create screen, All platforms writes the same brief in each platform's own form, inside each one's length.
