Camelot compatibility is deterministic music theory; track counts and key tags still depend on the analysis source and exact edit.

Why These Keys Work Together

The three compatibility moves on the Camelot wheel aren't arbitrary — they reflect real music theory. Adjacent keys (number ±1, same letter) share six of seven notes, which is why melodies ride over the boundary without clashing. The opposite-letter same-number move is the relative major/minor — those two keys share all seven notes, only the tonal center shifts. That's why mood-swap transitions feel jarring in mood but never harmonically wrong: the underlying scale is identical.

Data used
391-track reference snapshot; this page filters the 21 entries tagged 9A (E minor).
Source
Audio features sourced from ReccoBeats (https://reccobeats.com); track metadata via Spotify Search API. Spotify deprecated audio-features for new apps in Nov 2024. Manual label reference tracks use Beatport BPM/key metadata where available.
Evidence
21 reference tracks in the current snapshot are tagged 9A. BPM/key values come from ReccoBeats audio features and track metadata is resolved through Spotify.
How this page is made
Camelot key pages are generated from deterministic Camelot/Open Key mappings, harmonic-mixing rules, and a ReccoBeats/Spotify reference track snapshot. AI is not used to calculate key compatibility.

Camelot compatibility is deterministic music theory; track keys still depend on the analysis engine and the specific edit or remaster.
