Camelot Key Finder
Analyze a track's musical key, then map the harmonic transitions that mix with it. Built for DJs with Camelot and Open Key codes; audio stays in your browser.
Drop a track to map its Camelot-compatible mixes
MP3 / WAV / M4A / FLAC / OGG / AAC • up to 200MB • nothing gets uploadedBuild a Harmonic Mix with the Camelot Wheel
This tool is for the step after basic key detection: turning a track's key into a practical DJ transition plan. Drop in a file to get the musical key, Camelot code, Open Key code, relative key, and four compatible paths without uploading the audio.
From Audio File to Camelot Mix Plan
Analyze the Track Locally
Drop in MP3, WAV, M4A, FLAC, OGG, or AAC. Your browser decodes the audio locally; it never touches a server.
Map the Musical Key
The analyzer builds a chromagram and compares it against known profiles for all 24 major and minor keys, then converts the match to Camelot and Open Key notation.
Choose a Mixing Path
Use the result cards to hold the key, move one Camelot step up or down, or switch to the relative major or minor while staying harmonically compatible.
Relative Keys in Harmonic Mixing
Every minor key shares its notes with one major key — A minor and C major use exactly the same seven notes. These 'relative' pairs share a Camelot number (8A and 8B), which is why the second-best guess from any key detector is very often the relative key: harmonically they're nearly identical, differing mainly in which note feels like home.
For DJs this is good news: if the detector says 8A and the song is 'actually' 8B, every mixing decision you make from the Camelot code still works.

Frequently Asked Questions
How do I find a track's Camelot key?
Drop the audio file into the finder above. It detects the musical key, converts it to Camelot and Open Key notation, and maps four compatible transition paths. It's free, needs no signup, and the file never leaves your browser.
How accurate is automatic key detection?
Very reliable on harmonically stable music (pop, electronic, hip-hop). The most common 'miss' is the relative key — e.g. C Major instead of A Minor — which shares the same notes and the same Camelot number, so DJ mixing decisions still hold. That's why the result always shows the second-best guess too.
What is a Camelot code?
It is a DJ-friendly shorthand that arranges all 24 keys on a wheel of 12 numbers: 'A' for minor keys and 'B' for major. Adjacent codes are harmonically compatible, so you can plan mixes without translating the underlying music theory.
Does my file get uploaded?
No. The analysis runs entirely in your browser — your track never touches our servers. That's also why results appear within seconds even for lossless files.
Can this find the BPM too?
Yes, every analysis also measures tempo. This page keeps Camelot and harmonic transitions front and center; use the BPM Finder & Key Finder when you need tempo and key with equal weight.
Which keys mix well together?
Same Camelot code, one number up or down with the same letter, or the same number with the other letter (relative major/minor). After every analysis the finder lists exactly these compatible codes for your track.
