Camelot Wheel: Full Key Chart, Codes and Mixing Rules
The Camelot Wheel Explained: A Beginner's Guide for Producers
If you've ever seen codes like 6A or 11B next to a song's key information and wondered what they mean — that's the Camelot system. It's one of the most useful concepts in music production and DJing, and it's much simpler than it looks.
What Is the Camelot Wheel?
The Camelot wheel is a circular chart that maps all 24 musical keys to a number and letter system. It was developed to make harmonic mixing easier — giving DJs a simple code to find songs that will mix together without clashing.
But it's just as useful for producers. If you know the Camelot code of your sample, you instantly know what keys, chords, and melodies will work with it.
The wheel goes from 1 to 12, like a clock face. Each number has two versions: - A = minor key - B = major key
So the full system has 24 slots: 1A through 12B.
How to Read the Camelot Wheel
| Camelot Code | Key |
|---|---|
| 1A | A♭ Minor / G# Minor |
| 1B | B Major |
| 2A | E♭ Minor / D# Minor |
| 2B | F# Major |
| 3A | B♭ Minor |
| 3B | D♭ Major / C# Major |
| 4A | F Minor |
| 4B | A♭ Major |
| 5A | C Minor |
| 5B | E♭ Major |
| 6A | G Minor |
| 6B | B♭ Major |
| 7A | D Minor |
| 7B | F Major |
| 8A | A Minor |
| 8B | C Major |
| 9A | E Minor |
| 9B | G Major |
| 10A | B Minor |
| 10B | D Major |
| 11A | F# Minor |
| 11B | A Major |
| 12A | C# Minor |
| 12B | E Major |
How Compatibility Works
The simple rule: adjacent codes are compatible.
This means: - Same number, different letter — `8A` and `8B` share the exact same notes - One number higher — `8A` and `9A` - One number lower — `8A` and `7A`
So if your track is in `8A` (A Minor), the compatible keys are D Minor (7A), E Minor (9A), and C Major (8B).
Think of it like a clock. If you're at 8, adjacent positions are 7 and 9. That's the whole rule.
Why Producers Use It (Not Just DJs)
Finding samples that work together. If you pull two loops from different sample packs and want to layer them, knowing their Camelot codes tells you instantly whether they'll clash or blend.
Pitching samples to fit your key. If your beat is in `5A` (C Minor) and your sample is in `6A` (G Minor), you can pitch the sample to put it in the same key. Knowing the Camelot codes makes the math fast.
Writing melodies that fit. If you know your sample's Camelot code, you know what notes and chords are available to you. No trial-and-error on a keyboard.
Building a labeled sample library. Producers with organized libraries tag every sample with its key and Camelot code. When you're building a beat, you search by code instead of trying samples until something fits.
How to Find the Camelot Code of Any Song or Sample
You don't need to figure it out by ear. A key detection tool does it in seconds.
Many tools show the Camelot code. Tunebat lists it for over 100 million released songs, and Mixed In Key, rekordbox, Serato DJ Pro, Traktor and VirtualDJ show it for the tracks you analyze. In Ableton Live, our Key & BPM Finder (a Max for Live device, $14.99) shows the key and the relative key of a full track you drop onto it, which is what you need to place it on the wheel.
Changing Key Using the Camelot Wheel
Every step around the Camelot wheel = a specific number of semitones.
Moving one step clockwise (e.g. `8A` to `9A`) = up 7 semitones. Moving one step counter-clockwise (e.g. `8A` to `7A`) = down 7 semitones. Switching from A to B (minor to major) at the same number = same notes, different feel.
A Quick Example Workflow
You have a piano loop in `9B` (G Major) and a bass line in `8A` (A Minor). Are they compatible?
Check the wheel — `9B` and `8A` are not adjacent. They'll likely clash.
Your options: 1. Find a bass line in `9B`, `10B`, `8B`, or `9A` 2. Pitch the bass line from `8A` to `9A` (E Minor) — which is compatible with `9B`
That decision takes seconds when you understand the Camelot system.
Summary
The Camelot wheel takes harmonic compatibility — which takes years to internalize by ear — and turns it into a simple number-and-letter system anyone can use.
Once you understand it, you'll never layer two clashing samples again.
To get a song's key and BPM without any guesswork, Premix searches the song, reads its key (with the Camelot code) and BPM, and puts it in your project on the grid, with stems if you want them. See Premix
