One description, any genre

Describe the song in your head and hear it back from the AI Music Generator

Type what you hear in your head — style, mood, tempo, instruments, the kind of voice — paste your own lyrics if you have them, and the AI Music Generator returns two full versions with vocals and arrangement. Because each run interprets a description differently, comparing the versions is where most of the craft lives.

01

Say what the song sounds like

Genre first, then the details that shape it: tempo, instrumentation, vocal character, and the moment the track is for. A description such as "warm indie folk, acoustic guitar, brushed drums, close male vocal" reads like a brief and gives the model a clear target.

02

Choose generated or own lyrics

Let the prompt carry the theme on its own, or switch to Own lyrics and paste a finished set with Verse and Chorus labels. Labelled sections keep the arrangement following your structure instead of guessing one.

03

Judge both versions against your brief

Listen for whether the chorus lifts, whether the voice suits the words, and whether the arrangement leaves room for the hook. The stronger version is the one that matches your brief — not just the louder one.

04

Push the same idea across styles

Rerun the idea as a ballad, a dance cut, or an acoustic take and hear what the melody is made of. Cross-genre runs are also the fastest way to find out which style a song truly belongs to.

What makes a prompt work well with the AI Music Generator?

Specifics over adjectives. Mention tempo in BPM, the instruments that define the style, one or two reference moods, and the vocal type you want. A line like "dark synth pop, 100 BPM, analog pads, airy female vocal, big reverb on the chorus" gives the model far more to hold onto than a wall of feeling words.

How do you tell a good result from a lucky one?

Check the bones before the polish: does the chorus open up, does the second verse vary the first, does the ending land on purpose. A version that keeps its promise across repeated listens beats one that only surprises the first time.

Words already written?

Turn a finished lyric into a full demo — draft and compare complete sets in Lyrics Studio, then bring the winner back here as your Own lyrics.
