Harmonic Mixing Calculator — Camelot Wheel Key Matching

Camelot Wheel System

The Camelot wheel is the circle of fifths relabelled with numbers 1–12. Each step around the wheel is a perfect fifth, so adjacent keys share six of their seven notes. Compatible keys are:

• Same code: Perfect match (e.g. 8A to 8A)
• +1 (one step clockwise): A perfect fifth up — 7 semitones (e.g. 8A → 9A, A minor → E minor). Often heard as a subtle energy lift.
• −1 (one step anticlockwise): A perfect fourth up / perfect fifth down — 5 semitones (e.g. 8A → 7A, A minor → D minor). Often heard as an energy release.
• Same number, different letter: Relative major/minor — shares all seven notes (e.g. 8A → 8B, A minor → C major)

The A ring is minor keys and the B ring is major keys. On the major (B) ring, moving +1 adds one sharp (or removes one flat) to the key signature, mirroring the circle of fifths.

A note on energy

Every key listed here is harmonically compatible with your starting key — the relationship label describes how the move tends to feel, not a computed score. The Camelot number does not set a track's energy: energy comes from tempo, instrumentation, dynamics and arrangement, so always trust your ears when matching the vibe.
