Camelot notation labels each key with a number from 1 to 12 and a letter — A for minor, B for major. To convert a Camelot code to a standard key, read the number and letter off the wheel: 8A is A minor, 8B is C major. A notation converter does this instantly and also maps to Open Key, the other common DJ system.
Three systems describe the same 24 keys. They exist because different DJ software and analysis tools adopted different conventions.

| Camelot | Key | Open Key |
|---|---|---|
| 8A | A minor | 1m |
| 8B | C major | 1d |
| 9A | E minor | 2m |
| 9B | G major | 2d |
| 10A | B minor | 3m |
| 5A | C minor | 10m |
| 5B | Eb major | 10d |
| 7A | D minor | 12m |
Notice how the relative major and minor — 8A and 8B — share a Camelot number. That is the system's whole trick: switching the letter while keeping the number moves between a key and its relative, one of the smoothest transitions in harmonic mixing.
Your analysis app might tag tracks in Camelot, a collaborator might send you standard key names, and a third tool might use Open Key. Being able to convert means none of that slows you down — you read every library in whatever system you think in. Once the keys are in one notation, the Camelot wheel tells you which tracks mix together.
Read the number and letter: the letter A means minor, B means major, and the number maps to a root on the wheel. 8A is A minor, 8B is C major. A converter does the lookup for every code instantly.
Open Key is a DJ key system using the numbers 1–12 with 'd' for major (dur) and 'm' for minor (moll). It encodes the same harmonic relationships as Camelot but with different codes — its numbers are offset from Camelot's.
Different DJ software and analysis tools adopted different conventions. Standard names come from music theory; Camelot and Open Key are DJ shorthand built for harmonic mixing. Knowing all three lets you work across any platform.
They share a Camelot number, so they are the relative minor and major: 8A is A minor and 8B is C major. Switching the letter while keeping the number is one of the smoothest harmonic transitions a DJ can make.
