The Camelot Wheel — a DJ's guide to harmonic mixing
The Camelot Wheel is a shorthand for musical keys built for DJs. Instead of memorising which sharps or flats play well together, you match numbers on a clock. Two tracks whose Camelot codes sit next to each other on the wheel will almost always mix without a key clash.
What the numbers and letters mean
Every musical key maps to a code like 8A or 8B. The number (1–12) is the position on the wheel, like hours on a clock. The letter is the mode: A = minor, B = major. So 8A is A minor and 8B is C major — they share the same notes, which is why they mix perfectly.
- 1AA♭ minor
- 2AE♭ minor
- 3AB♭ minor
- 4AF minor
- 5AC minor
- 6AG minor
- 7AD minor
- 8AA minor
- 9AE minor
- 10AB minor
- 11AF♯ minor
- 12AD♭ minor
- 1BB major
- 2BF♯ major
- 3BD♭ major
- 4BA♭ major
- 5BE♭ major
- 6BB♭ major
- 7BF major
- 8BC major
- 9BG major
- 10BD major
- 11BA major
- 12BE major
The four safe transitions
From any track, four next tracks are guaranteed to be harmonically compatible:
- 1 · SAME CODE (PERFECT MATCH)
8A → 8A. Same key, zero clash. Great for long, blended transitions.
- 2 · +1 OR −1 (NEIGHBOUR)
8A → 7A or 8A → 9A. One step clockwise or counter-clockwise on the same ring.
- 3 · SWITCH LETTER (RELATIVE MAJOR/MINOR)
8A → 8B. Same number, switch A↔B. Adds emotional lift or drop without a key change.
- 4 · +7 (ENERGY BOOST)
8A → 3A (jump seven forward, wrapping the wheel). Advanced move — used to lift energy on peak-time drops.
Applying it in Traktor
Traktor writes the Camelot code (or the musical key) into every analysed track. PEAKFLOWTRAXX reads that field, orders your set using the four rules above, and flags any risky jumps before you export back to .nml. Load your collection.nml from the set builder to try it.
Camelot Wheel FAQ
Is the Camelot Wheel the same as key notation?
It is a re-labelling of the circle of fifths. Every Camelot code maps 1:1 to a musical key — the numbers just make compatible pairs adjacent instead of a fifth apart.
Do I have to mix in key?
No. Harmonic mixing is a tool, not a rule. Percussive intros, drum-only sections and long EQ swaps let you break the wheel cleanly. Use it as a default and break it deliberately.
What about ±2 or diagonal jumps?
Two-step jumps (8A → 10A) usually clash. If a track's melody is buried, you can get away with it — but treat it as risky and cut the outgoing track early.
