## Composition Quick Reference

When prompting Lyria 3 models, combine these structural building blocks:

1. **Genre & Style**: Define the core musical style (e.g. `lo-fi hip-hop`, `synthwave`, `chamber orchestra`, `delta blues`).
2. **Instrumentation**: Specify lead and rhythm instruments (e.g. `Rhodes piano`, `808 bass`, `acoustic nylon guitar`, `cello section`).
3. **Tempo & Key**: Set musical parameters (e.g. `120 BPM`, `in D minor`, `slow waltz tempo`).
4. **Vocals vs Instrumental**: Add `"Instrumental only, no vocals"` for instrumental beds, or provide bracketed section lyrics (`[Verse 1]`, `[Chorus]`).
5. **Timestamps (Pro only)**: Use time ranges (`[0:00 - 0:15] Intro...`) to coordinate dynamics.
