Music

Use submit_music to create a new instrumental background-music or vocal-song audio asset. For an explicit sung song, lyrics-to-song request, or vocal MV song, read references/song.md for the lyric workflow, then call submit_music with generationType:"song". When a request only says music, soundtrack, theme music, or 配乐 and does not specify vocals, ask the user to choose vocals or instrumental first instead of assuming.

The tool submits one generation job and returns a jobId. The generated audio asset is available after track_progress reports completion.

Capability Boundary

Mureka creates a new original music asset; it does not edit, clean up, remix, separate, or adjust existing audio.

Mureka also cannot guarantee exact beat, drop, lyric, or timestamp alignment. Generate the music asset first, then use timeline tools for placement, trimming, looping, fades, and ducking. If the user requires precise beat-level sync, explain that this must be handled as a timeline/audio edit rather than guaranteed by the generation model.
