01 / Begin

Leave room for surprise.

Your lyrics, an open direction, or nothing at all. Explore new words and sounds, hold onto what works, and let the next take take you somewhere.

02 / Compose

Get closer to the music.

Open YuE2's score. Change the harmony, move a phrase, shift the key. Describe a change in words or reach for the notes yourself.

03 / Refine

Small studies. Better takes.

Try a few lines before a full performance. Keep its phrasing and explore another rendering, or let the producer propose a fresh take. Compare them at the same moment.

From an idea to a composition

A score you can work with.

Compose before you perform. See the voices unfold, audition them together or apart, edit the notes, and fit the recording to the score. Every take keeps the ingredients for its next variation.

A shape for every sound

Watch the music unfold.

Lines carry the waveform through a floating form. Bass opens its contours; each attack leaves a ripple. Shape its surface and motion, then keep the living artwork and complete song together as an MP4.

Your next take is waiting.
