Original: Camelot Wheel for Developers: Harmonic Mixing Without the Music Theory PhD

Short summary

A developer-oriented explanation of the Camelot wheel — a numeric mapping of musical keys that simplifies harmonic mixing for DJs. Covers the compatibility rules (same, relative, adjacent, energy boost/drop) and includes a complete dependency-free Python implementation of the compatibility checker. Also mentions a hosted API exposing the same logic.

  • •Camelot wheel maps 24 keys to a clock face with A (minor) and B (major) variants
  • •Compatible keys share a position, are adjacent, or share the same number with opposite letter
  • •Full Python implementation provided with optional +7/-7 energy-boost variants

Generated with AI, which can make mistakes.
