Camelot Wheel Key Mixer

All 24 keys arranged on a clock: numbers 1–12, with A for minor and B for major. Adjacent numbers are a fifth apart (the circle of fifths in disguise), and same-number A/B pairs are relative keys sharing all their notes. Compatible mixing = same code, ±1 number, or the A↔B swap — arithmetic instead of theory.

Every major DJ platform analyzes keys (Rekordbox, Serato, Traktor, Engine), often displaying Camelot codes directly, and dedicated taggers exist for libraries. Detection is imperfect — a few percent of tracks get mislabeled, and anything you've key-shifted has moved from its tag — which is why ears keep veto power.

Jumping +2 on the wheel (a whole step up, e.g. 8A → 10A). It's not strictly diatonic, but when both tracks are harmonically simple — driving basslines rather than lush chords — the lift reads as excitement rather than clash. A staple for building a peak-time set.

Anywhere two pieces of music must coexist: choosing a sample that sits in your beat's key (or one pitch-shift away), writing a bridge that modulates somewhere natural, layering a vocal from another track. Same wheel, same moves.
