# AI music generator > Describe a song in one sentence and hear it sung, or bring your own lyrics and style: vocals and instruments, 30 s to 4 min, MP3 out. 3 credits per 30 s. Type what the song is about and how it should feel: Music One writes the lyrics, picks a style, names it and sings it, in two takes so you keep the better one. Or go Custom: your words with section tags, your sound in a few style words, the length you want. Every song lands in your Library as an MP3. ## How it works - 1 · Simple: describe the song in one sentence (genre, mood, what it is about), or press Surprise me for an idea. The songwriter writes the lyrics, the style and a title, included in the price. - 2 · Custom: write the lyrics yourself with section tags on their own lines ([Intro], [Verse], [Pre-Chorus], [Chorus], [Bridge], [Outro], one click away in the Syntax menu) and describe the sound in Style: language, vocals, genre, tempo, instruments. Lyrics left empty? Surprise me drafts them for your style, free. - 3 · Pick the length (30 seconds to 4 minutes, in steps of 30), flip Instrumental for no vocals, choose one or two takes, and Generate. ## Writing a song that works - Keep the sound in Style and only the sung words in Lyrics: everything in the lyrics gets sung, instructions included. - A chorus that comes back twice is what makes a song stick. Tags shape the arrangement: a [Bridge] changes the mood, an [Outro] lands the ending. - Fit the words to the length: about one sung line every four or five seconds. The gauge under the lyrics warns when there are more lines than the song can hold. - Describe the sound with genre, era and instrument words rather than an artist's name: those are the words the engine follows. ## Pricing Music One is 3 credits per started 30 seconds of song, per take, billed on the length you ask for. A one-minute song is 6 credits for one take; a two-minute song 12, and the four-minute maximum 24. The studio renders two takes by default, each its own performance of the same song, and a take that fails is refunded on its own. ## Starting points - **Small-town synth-pop** — A melancholy synth-pop song about leaving a small town at night, warm female vocal - **Late-night lo-fi** — A slow lo-fi hip-hop song for a rainy night drive, dusty drums, soft keys and a hushed vocal - **Stadium anthem** — An uplifting rock anthem about getting back up after a fall, big drums and a shout-along chorus - **Acoustic love song** — A tender acoustic folk song about two strangers sharing an umbrella, male vocal and fingerpicked guitar ## FAQ ### Do I have to write lyrics? No. In Simple mode one sentence is enough: the studio writes the lyrics, the style and a title, then sings them. In Custom mode you can leave the lyrics empty and press Surprise me, which drafts them for free; Enhance polishes lyrics you wrote, on a paid plan. ### How long can a song be? From 30 seconds to 4 minutes, in steps of 30 seconds. The song may find its ending a little before the length you chose; the Library shows its real length. ### How much does a song cost? 3 credits per started 30 seconds, per take: 12 credits for a two-minute song, one take. Two takes cost twice that. A take that fails is refunded. ### Can I make instrumentals? Yes: switch on Instrumental. There are no vocals and the lyrics are left out; describe the sound in the idea or in Style. ### Which languages can it sing? Put the language first in Style ("Spanish, warm male vocal…") and write the lyrics in that language; in Simple mode, say the language in your sentence. English is the strongest. ### Is there an API? Yes: POST /v1/music/generations with a prompt, or a style and lyrics. It is asynchronous: each take is a job you poll at GET /v1/music/generations/{id}, or receive with a music.generation.succeeded webhook. ## Related - https://eroq.ai/models/eroq-music-one — Music One - https://eroq.ai/compare/eroq-vs-suno — eroq vs Suno - https://eroq.ai/compare/eroq-vs-elevenlabs-music — eroq vs ElevenLabs Music - https://eroq.ai/use-cases/songs-for-creators — Songs for creators - https://eroq.ai/use-cases/brand-jingles — Brand jingles - https://eroq.ai/help/voice/make-a-song — How to make a song - https://eroq.ai/blog/how-to-write-lyrics-for-ai-songs — How to write lyrics for AI songs - https://eroq.ai/docs/music — Music API - https://eroq.ai/tools/ai-voice-generator — AI voice generator --- This page as HTML: https://eroq.ai/tools/ai-music-generator · Studio: https://eroq.ai/studio · Docs: https://eroq.ai/docs · Machine index: https://eroq.ai/llms.txt
