What is the Camelot wheel?

The Camelot wheel is a visual tool that arranges all 24 musical keys in a circle, numbered 1-12 with A (minor) and B (major) suffixes. Adjacent keys on the wheel are harmonically compatible, making it easy to find keys that mix well together without clashing.

What are the basic rules of harmonic mixing?

The three safe moves are: same key (e.g. 8A to 8A), one position up or down (e.g. 8A to 7A or 9A), and switching between relative major/minor (e.g. 8A to 8B). These transitions sound natural because they share most of the same notes.

Can I mix tracks that are not harmonically compatible?

Yes, but clashing keys can sound dissonant during transitions. Techniques like quick cuts, using effects, or mixing in sections without strong melodic content can help. Some DJs also use key lock and pitch to shift tracks into compatible keys.

How do I find the key of my tracks?

Most DJ software (Rekordbox, Traktor, Serato, Mixed In Key) can analyse tracks and display their key in Camelot notation. The analysis is usually accurate but can occasionally be off by a semitone, so trust your ears as well.

How We Calculate This

Camelot Wheel System

The Camelot wheel maps all 24 keys to a numbered circle. Compatible keys are adjacent on the wheel:

Same number: Perfect match (e.g. 8A to 8A)
+1 or -1: Move one position (e.g. 8A to 7A or 9A)
Same number, different letter: Relative major/minor (e.g. 8A to 8B)

The A column is minor keys and the B column is major keys. Moving +1 adds one sharp (or removes one flat) to the key signature.

Compatibility Score

The compatibility score blends harmonic distance (semitone tolerance) with energy level matching (energy weight) to give a holistic match rating for each compatible key.
