Interactive harmonic mixing guide for DJs. Click any key segment to reveal compatible keys for seamless transitions — no theory knowledge required.

The Camelot Wheel, created by DJ Mark Davis and popularised by the Mixed In Key software, is a system that assigns a number and letter (A for minor, B for major) to each musical key. Keys that share the same number or adjacent numbers are harmonically compatible — they share most of the same notes, so mixing between them sounds smooth and musical.
The rules are simple: you can mix to the same key (e.g. 8A → 8A), move one number up or down (8A → 7A or 9A), switch between minor and major at the same position (8A → 8B), or combine those moves. Use this wheel before your sets to plan key-compatible transitions and take your DJ sets to the next level.

1. Find the key of the track you are playing — from your DJ software, a key-detection tool or the track's metadata — and click its segment on the wheel.
2. The wheel highlights the compatible keys: the same code, one number up or down, and the other letter at the same number.
3. Pick your next track from one of those keys for a smooth, clash-free transition.
You are playing a track in A minor, which is 8A. Safe next keys are 8A (another A minor track), 7A (D minor), 9A (E minor) and 8B (C major, the relative major). Moving 8A → 9A lifts the energy slightly; 8A → 8B keeps the same notes but brightens the mood. A jump to 3A (B♭ minor) shares far fewer notes and will clash unless the blend is very short.
How do I find the key of a track?
Most DJ software — rekordbox, Serato, Traktor — detects the key when it analyses a track and
can show it in Camelot notation. Detection is not perfect, so trust your ears if two
compatible tracks still clash. If you know the chords, the Chord Analyzer can confirm the
key.
Why does moving one number sound smooth?
Neighbouring numbers are a fifth apart, and keys a fifth apart share six of their seven
notes. 8A (A minor) and 9A (E minor) differ only by F versus F♯, so the melodies and
harmonies of both tracks fit together.
What is an energy boost mix?
Some DJs jump two numbers up (8A → 10A) or one semitone up (8A → 3A) to lift a peak moment.
These moves share fewer notes, so keep the overlap short or blend over a drums-only section.
