The Camelot Wheel is the standard system for harmonic DJ mixing. It assigns each key a number (1–12) and letter (A=minor, B=major). Adjacent keys on the wheel sound compatible when mixed together, allowing smooth transitions without clashing harmonics.

How to Use the DJ Harmonic Key Mixer
This DJ harmonic mixing tool uses the Camelot Wheel system to find keys that sound musically compatible when mixed together. Select your current track's key to see all compatible mixing options.
The Three Harmonic Mixing Rules
Rule 1 — Same key: Mix with the identical Camelot position (e.g., 8B into 8B). Perfect for extended mixing.
Rule 2 — Adjacent number: Move ±1 on the number (e.g., 8B to 7B or 9B). This moves up or down a perfect fifth/fourth — the most natural key change in music.
Rule 3 — Letter swap: Same number, change A to B or B to A (e.g., 8A to 8B). Switches between relative major and minor — creates a mood shift without clashing.
BPM Compatibility
Harmonic compatibility is only part of the equation. BPMs also need to be compatible. Most DJs consider tracks within ±8% BPM compatible (can be beat-matched with pitch/time stretching). Beyond that, half-time or double-time mixing may be needed.

What is the Camelot Wheel?
The Camelot Wheel is a system for harmonic mixing developed by Mark Davis. It arranges all 24 major and minor keys in a clock-like circle using numbers (1–12) and letters (A for minor, B for major). Adjacent keys on the wheel sound harmonically compatible when mixed together.
What keys are compatible for harmonic mixing?
Three main rules: (1) Same key — mix with identical Camelot position. (2) Adjacent energy — move ±1 number (e.g., 8A to 7A or 9A) for gentle transitions. (3) Relative switch — change A to B or B to A at the same number (e.g., 8A to 8B) to go between relative major/minor.
Can I mix tracks with different BPMs?
Yes, within limits. Most DJs consider ±5–8% BPM compatible (can be beat-matched with pitch adjustment). Wider BPM gaps require more creative mixing (long transitions, FX, acapellas). This tool shows the ±1 and ±2 BPM ranges that work without pitch problems.
How do I find the key of a track?
Use music analysis software like Mixed In Key, Rekordbox, or Serato (which auto-detect keys), or use your ear combined with a piano/keyboard. Many tracks also list key metadata in music stores or Beatport.
What is the difference between 8A and 8B?
In Camelot notation, B keys are major and A keys are minor. 8B = Ab major, 8A = F minor. They are relative major/minor pairs (sharing the same notes) and can be mixed together for a mood shift without clashing.
