## How to describe musical needs

Music cue words should include purpose, mood, duration and sound elements.

1.  Indicated use: Advertisement, podcast, short video, meditation, game, brand film or song.
2.  Explain the vocal/pure music, language, lyric themes and singing feel.
3.  State the genre, tempo, mood, instrumentation, and reference atmosphere.
4.  If there is a picture, video or audio reference, explain what it affects.

## Lyrics and multiple versions

Song tasks usually require looking at the lyrics or direction before confirming the generation.

- The lyrics should have clear language, theme, structure and whether they rhyme.
- Multiple songs should be confirmed one by one to avoid losing control of the batch at once.
- BGM can generate multiple emotional versions depending on the purpose.
- When video synchronization is required, the duration, rhythm points and picture segments must be specified.
- When you need podcast structure, leave it to Onir, don’t ask Lydi to write the entire show.
