The Camelot wheel: compatible keys at a glance
Pick a key on the wheel. The three that light up mix with it: the relative major or minor, and the neighbors a fifth away. Arrow keys walk the wheel.

How harmonic mixing works
The wheel renames the 24 musical keys as clock positions: 1 to 12, with B for major and A for minor. Keys that share a number are relatives, built from the same notes, and always blend. Keys one step apart on the same ring sit a fifth apart, sharing all but one note. Mixing inside that neighborhood keeps two tracks from clashing, and the wheel turns the theory into arithmetic: from 8B, anything marked 8A, 7B or 9B works.
Find the key of your own tracks
The wheel is only useful once you know the key. The song key & BPM analyzer reads the key, Camelot code and decimal BPM from any audio file in your browser, with the honest confidence and alternates this wheel assumes. And when the song is only in your ears, the tap tempo tool counts the BPM from your fingers.
