BPM & Key Finder

Drop the song into the finder above, or press Choose songs and pick it. Its BPM, key, relative key and Camelot code appear in the results within a few seconds. Add more songs at any time; each one gets its own row.

Many songs can be counted at two speeds. A drum and bass track can feel like 87 or 174 BPM, and a slow ballad like 70 or 140. Tools that disagree by a factor of two are counting the same beat differently, so the finder lists the half- and double-time values under each BPM. Use the one that matches how songs in that genre are usually counted.

E minor and G major are relative keys: they use the same notes and the same key signature. The chords and the melody decide which one feels like home, and some songs lean both ways. That is why the finder shows the relative key under each result. On the Camelot wheel they share a number, 9A and 9B, so the song mixes well with either.

The Camelot wheel gives every key a number from 1 to 12 and a letter: A for minor keys, B for major keys. C major is 8B, A minor is 8A and G major is 9B. Songs with the same code, codes one number apart, or the same number with the other letter usually sound good mixed together, which makes the codes a quick guide for harmonic mixing.

Songs with a steady beat and a clear key give the most reliable results. Each song gets one BPM and one key, taken from its main part, so a song that speeds up or changes key along the way shows the tempo and key of that part. Live recordings with a drifting tempo, spoken word, drum solos and ambient pieces may show No steady beat or Key unclear. When a result matters, check it by ear, for example by playing along in the detected key.

Yes. Choose or drop as many files as you like. They are analyzed one after another in the order you added them, and each result appears as soon as that song is done. You can add more songs while the list is working, press Stop to skip the rest, and save every finished result with Export CSV.

MP3, WAV, M4A, FLAC and OGG audio, plus common video files such as MP4, MOV and WebM, where the soundtrack is analyzed. Each file can be up to 500 MB.

No. Your browser opens and analyzes each file on your own device, and nothing is sent to a server. The list stays in this browser tab while you move around the site; reloading or closing the page clears it.

Export the list as CSV to sort it in a spreadsheet, or press Change key or tempo next to a song to open it in the pitch changer. There you can move it to a key that suits your voice or instrument, change its speed, and save it as MP3 or WAV.

BPM stands for beats per minute, the tempo of a song. At 120 BPM there are two beats every second, a common tempo for dance music, while ballads often sit between 60 and 80 BPM.
