Harmonic mixing with the Camelot wheel
Harmonic mixing means picking the next track in a key compatible with the current one — the transition sounds musical instead of clashing. The Camelot wheel maps musical keys to codes (1A–12B) that make the choice mechanical: same numbers match, neighbors match.

The wheel's rules
Starting from the current track's key (say 8A):
- Same code (8A → 8A): always safe
- ±1 on the number (8A → 7A or 9A): smooth transition
- Same number, flipped letter (8A → 8B): minor to major
- +1 with a letter flip (energy boost): lifts the floor
Key isn't enough: energy
Two tracks in 8A can have opposite moods. That's why Beat.Tools measures energy (1–10) alongside key — you plan the set's arc (warm up, hold, peak) instead of just harmonic compatibility. Fractional key shows when a track modulates mid-way.
In practice, in Beat.Tools
The Camelot wheel lives inside the tool with compatible pairs highlighted from the selected track. Audition the transition with stems (mute the vocal, isolate the kick) before locking the sequence, then export to Rekordbox with TKEY already written.
Frequently asked questions
Do I need music theory?
No. That's exactly what the Camelot wheel is for: follow the codes (same number or a neighbor) and the harmony works.
What is an energy boost?
Going +1 on the number while flipping the letter (e.g. 8A → 9B). Perceived energy rises — a classic move to lift the floor.
Can I ignore harmony?
Sure — on quick EQ cuts or percussive tracks key matters less. The wheel is a tool, not a law.
Does Beat.Tools detect key by itself?
Yes, locally in the browser, as average and fractional Camelot. No audio upload.
