Mix in harmony.
Drop a track or click any position. See the Camelot number plus three harmonically-compatible neighbours for clean transitions.

Outer ring is major, inner ring is minor. Numbers run 1–12 around the wheel; letter A means minor, B means major.
/ Method
How the Camelot
wheel works.
Method: chroma-based key detection mapped to Camelot positions · Built by Sample Vault · v1.0
Same key detection as our key-detector tool, mapped onto the wheel DJs already think in.
/ 01 — The wheel
Each of the 24 keys (twelve majors, twelve minors) sits at one of 24 positions on the wheel. The number is the position around the dial; the letter says whether it's a major (B) or its relative minor (A).
/ 02 — Compatibility rules
Tracks at the same number mix cleanly because they share a key signature. Step ±1 on the same letter for a natural lift or drop. Swap the letter for the relative major/minor — same chords, different mood.
/ 03 — Detection
Drop a track and we run the same chroma + 24-template matching the desktop app uses to detect key. Files where the tonic is ambiguous return no key rather than a confident wrong answer.
/ 04 — Local + shareable
The file never leaves your machine. Loads once, runs offline thereafter. URLs encode the selection (?key=C&scale=major) so you can share or bookmark a position.
/ Across your library
From one file
to fifty thousand.
Looking up one track on the wheel is fine. Pulling every track in 8B or 9A from a 40,000-file library — and filtering by BPM and brightness on top — is the desktop app. Same key detection, run across every folder you point it at.
