Key finder, explained
Drop a song to find its key, its Camelot code for harmonic mixing and its tempo. Analyze many songs at once; the audio stays on your device.
How the key is found
The finder measures how much of each of the 12 pitch classes the song contains and compares that profile with all 24 major and minor keys, using the key profiles from Krumhansl and Kessler’s listening experiments.
Keys that share most of their notes are easy to confuse, so the runner-up is shown as well. The most common mix-ups are the relative key (A minor and C major) and keys a fifth apart.
Camelot codes for harmonic mixing
DJs use the Camelot wheel to find songs that mix well: the same number, or one step up or down, sounds in tune. A minor is 8A, its relative C major is 8B, and E minor next door is 9A.
