Free Song Key & BPM Finder
Upload a song to find its tempo (BPM), musical key and Camelot code. Everything happens in your browser.
How to find the BPM and key of a song
- Choose a song file from your phone or computer.
- Wait a few seconds while the song is analysed.
- Read the tempo (BPM), key and Camelot code. The bars show how strongly each note is used in the song.
What is the Camelot code?
The Camelot wheel gives every key a number and a letter (like 8A for A minor or 8B for C major). DJs mix songs whose codes are the same or next to each other, because they sound good together.
How accurate is it?
The results are estimates. Tempo is usually very reliable for songs with a steady beat. Key detection works best on songs with clear harmony; songs with heavy drums or many key changes can be less certain, which the confidence label shows. Only the middle part of long songs (up to 2.5 minutes) is analysed.
Is my file uploaded?
No. The audio is analysed entirely inside your browser, so nothing is sent to our servers.
