How camelot wheel calculator works
Camelot notation is the lingua franca of harmonic mixing. Every key gets a number from 1 to 12 — its position on the circle of fifths, starting from 8B = C major — and a letter: A for minor keys, B for major. Each A/B pair sharing a number are relative keys, so 8A is A minor and 8B is C major. The wheel exists because tracks whose keys sit close together on the circle share most of their notes, so blends sound musical instead of clashing.
Type a key in any common form — "C major", "Am", "Ebm", "F#" — or paste a code straight from your DJ software such as "8A". The calculator resolves it to the official code, the full key name, any standard enharmonic aliases (Db/C#, G#m/Abm), and the relative key on the same number. It also shows the semitone distance from your key to each suggestion, so you can see exactly how far each move travels.
The compatibility lists follow the standard Mixed In Key moves: the same number with the other letter (8A ↔ 8B), one number down or up keeping the letter (7A, 9A), the energy boost two numbers up keeping the letter (10A), the energy drop two numbers down (6A), and the two deliberate-contrast moves: three down (Pay Attention) and five down (Jaws). Numbers wrap around at the 12/1 edge. Use the lists to shortlist tracks — phrasing, tempo and arrangement still decide whether the blend works.
