Harmonic Mixing with the Camelot Wheel: A Quick Guide for DJs
Harmonic mixing means moving between tracks whose keys sound good together, so long blends do not clash. The Camelot wheel turns music theory into numbers you can read at a glance.
How Camelot notation works
Each of the 24 musical keys gets a number from 1 to 12 and a letter: A for minor keys, B for major keys. For example, A minor is 8A and C major is 8B. Neighbouring numbers are a fifth apart, which is why they blend smoothly.
Which keys mix together
- Same key (8A → 8A) — The safest move. Works for long blends and layering.
- One step around the wheel (8A → 9A or 7A) — Smooth and natural. Going up (+1) tends to lift the energy; going down (−1) relaxes it slightly.
- Switch letter, same number (8A → 8B) — Moves between the relative minor and major: same notes, different mood. Minor to major brightens the room.
- Energy boost (+2, or +7 for a semitone up) — A bigger jump that works over short transitions or breakdowns. Use it sparingly.
Tempo matters too
Key compatibility only helps if the tempos are close. Keep neighbouring tracks within a few BPM of each other, and remember that pitching a track up or down without key lock also shifts its key — about one semitone for every 6% of tempo change.
Sorting a whole playlist
Doing this by hand for a 20-track set is slow. Tools such as Mixed In Key and Rekordbox analyse keys in your library. On PickTrack chart tracks already show their BPM and Camelot key, and harmonic sort (PickTrack Pro) orders a playlist in one tap so each step moves to a compatible key with a smooth tempo flow; the result can be sent to your SoundCloud.
For the hands-on side — setting a tempo window, turning a key into a short list of targets and filtering charts and your library — see the practical guide to finding tracks by BPM and Camelot key.

FAQ
What keys mix well in the Camelot wheel?
The same key, one number up or down with the same letter (for example 8A to 9A or 7A), and the same number with the other letter (8A to 8B). A two-step jump can work as a short energy boost.
What do A and B mean in Camelot keys?
A is a minor key and B is a major key. 8A (A minor) and 8B (C major) share the same notes, which is why they mix together.
Does harmonic mixing matter for every genre?
It matters most for long, melodic blends — house, techno, trance, melodic genres. For fast cuts and percussive transitions it matters less, but it still helps avoid clashing basslines and vocals.
