Song Key Finder
Drop a song to find its key, such as A minor or E major, along with its tempo in BPM and the Camelot code DJs use for harmonic mixing. Your audio never leaves your device.
MP3, WAV, M4A, OGG and FLAC. Analysis takes a few seconds.
How often each note sounds across the song.
How does the key finder work?
It measures how strongly each of the 12 notes sounds across the whole song and compares that with the typical pattern of every major and minor key.
What is the Camelot code?
A number and letter used by DJs for harmonic mixing. Songs with the same code, or one number apart, usually blend well. A means minor and B means major.
Why does it show a second key?
Some songs fit two keys almost equally well, often a key and its relative major or minor, which share the same notes. The second suggestion helps in those cases.
