Tips

  • Include genre, mood, tempo, and instruments in your prompt for the best results.
  • BPM matters — specify it if you need the music to match a specific pacing (e.g., "120 bpm" for upbeat, "70 bpm" for relaxed).
  • Set volume to 0.2-0.4 when using as background under narration — it shouldn’t compete with speech.
