What Is the Camelot Wheel? Harmonic Mixing Explained
Updated June 2026 · by Loopin
The Camelot wheel turns music theory into a clock you can read at a glance. It's how DJs mix tracks that sound good together — and producers use it to find samples that sit in the same key.
The numbers and letters, decoded
Every key gets a code: a number from 1 to 12 and a letter — A for minor, B for major. So A minor is 8A and C major is 8B. The number is the position on the wheel; the letter tells you major or minor. That’s the whole system.
Why bother? Because keys that sound good together end up next to each other on the wheel. Instead of remembering that A minor relates to C major, you just read that 8A and 8B share a number — they’re compatible.
The rules of harmonic mixing
To move from one track to another smoothly, change the code by a small, predictable step: stay on the same number (8A → 8B) to switch between relative minor and major; or move one number up or down on the same letter (8A → 9A or 7A). Both keep the transition in key.
Bigger jumps — say 8A to 2A — clash, because the keys share few notes. The wheel makes the safe moves obvious: adjacent codes blend, distant codes fight.
Find any track's Camelot code instantly
You don’t have to know a song’s key to get its Camelot code. Drop the track into the free key & BPM finder and it returns the key and the Camelot code together — for example 11A. From there, the compatible tracks are the ones whose codes are one step away.
Pair that with matching tempo and your transitions lock in. The same finder reports the BPM, so you can line up key and tempo before you ever touch the crossfader.
It's not just for DJs
Producers use the wheel too. Building a song from samples? Pick loops with the same or adjacent Camelot codes and they’ll stack in tune. Adding a vocal feature recorded in a different key? The wheel shows you whether it’ll sit or clash, and which direction to pitch it.
Once your in-key arrangement is recorded, finish it with a clean master. Harmonic choices set the song up; mastering makes it translate.
Frequently asked questions
What do the A and B mean in Camelot codes?
A means a minor key and B means a major key. The number is the position on the wheel. So 8A is A minor and 8B is C major — sharing a number means they're relative keys that mix well.
Which Camelot keys mix well together?
Codes that are next to each other. Keep the same number and switch letter (8A to 8B), or move one number up or down on the same letter (8A to 7A or 9A). Those moves stay in key; larger jumps clash.
How do I find a song's Camelot code?
Use a key finder that reports it. The Loopin key & BPM finder shows the key alongside its Camelot code in seconds, so you don't have to convert keys by hand.
