Features

Everything a song needs.
Nothing it doesn't.

Prompt to full song.

Name, age, hobbies, a city, a feeling — put it in a sentence. A local language model writes singable lyrics with verses and a chorus, then YuE2 composes and performs them.

20+

Languages.

English, Hindi, Chinese, Japanese, Korean, Spanish, Punjabi and more — written in their own script.

✦

Write lyrics, then tweak.

One click fills in the lyrics, title and style. Edit any word before you create.

♫

A real score.

Every song starts as sheet music with melody and chords. Read it alongside the lyrics.

⟳

Variations.

Keep the composition and the singing, re-roll the sound. Seconds, not minutes.

◐

Song Cover.

Give it a recording. Cadenza hears the melody and sings it again in any style you describe.

≋

Instrumental.

Flip one switch for a track with no vocals — study beats, intros, background music.

Under the hood

Score first.
Then the song.

01

Write

A local LLM turns your sentence into lyrics, a title and a production brief.

02

Compose

YuE2 writes a score: melody and chords in ABC notation.

03

Sing

It performs the score as audio codes, then flow matching paints the sound.

04

Master

A neural decoder renders 48 kHz stereo, normalised and ready to play.

Questions.

Is it really free?

Yes. Cadenza is open source and everything runs on your own computer, so there's nothing to pay for and no limit on how many songs you make.

How long does a song take?

It depends on your hardware and the song length. On an Apple M1 Pro, expect a few minutes for a three-minute song. Variations of a song you've already made are much faster.

What do I need?

A Mac with Apple silicon, or a Windows or Linux PC with a recent GPU and at least 16 GB of memory. About 10 GB of free disk space for the models.

Can I sell the music I make?

No, not with the default model. The YuE2 weights are licensed CC BY-NC 4.0, which means non-commercial use only. Personal songs, gifts, family videos and experiments are all fine.

Can I use a bigger language model?

Yes. Pick a larger Gemma size in Models, or switch to Ollama or any OpenAI-compatible server in Settings and use any model you like, up to 70B on a big machine.
