FAQ: Scale Finder
What's the difference between key and scale?
Key indicates the tonic and major/minor quality. Our tool detects both, plus Camelot for DJ workflows.
Does it support modal tracks?
Modal tracks are flagged with the closest major/minor match plus a confidence indicator.
Is it free?
Yes. Free, unlimited and browser-only.
How accurate is the detection?
Highly accurate on tracks with strong tonality. For ambiguous tracks, confidence is reported alongside the result.
Can I use detected scales in your AI Music Generator?
Yes — copy the detected scale into the AI Music Generator's prompt to lock generated tracks to that scale.
