Composition Quick Reference #

When prompting Lyria 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 (Lyria 3.5 / Pro): Use time ranges ([0:00 - 0:15] Intro...) to coordinate dynamics.
