The Camelot wheel, and the Camelot key of any MP3
Click a code to see the keys that mix with it and why they work. Already know your key? The wheel translates it to a code in one click, free and with no file. Don't know it? That part has to come from the recording — upload the track and we read the key out of the audio.
Outer ring: B codes (major keys). Inner ring: A codes (minor keys). Use the arrow keys once the wheel has focus.
A track in A minor is 8A in Camelot notation. The three codes below share almost every note with it, which is why they are the safe places to mix into.
- 8AE minorOne step clockwise
Up a fifth. The two keys share every note but one, so nothing clashes — and because the new key sits higher on the circle, the mix tends to feel like it lifts. This is the standard way to build energy across a set.
- 8AD minorOne step counter-clockwise
Down a fifth. Also one note apart, so it is just as safe as going the other way, but it settles rather than lifts. Useful when you want the energy to come down without the mix sounding like a mistake.
- 8AC majorSame number, major
A minor and C major are built from exactly the same seven notes — they are relative keys. Nothing can clash, because there is nothing different to clash. What changes is the mood: the track you move into will feel brighter.
Know the key? Get the code
Pick a root note and a mode. This is a lookup, not an analysis: the Camelot code is decided by the key alone.
A number and a letter
The wheel is the 24 keys on a clock face. The number, 1 to 12, is the position; the letter is the mode — A for minor, B for major. B for bright, if you need a way to remember which is which. A minor is 8A, and the major key sitting on the same number, C major, is 8B.
Neighbours share their notes
Two codes one step apart on the wheel differ by exactly one note out of seven. That is the whole trick: 8A into 9A cannot clash, because there is almost nothing there to clash. Going clockwise tends to lift the energy; counter-clockwise settles it.
Same number, other letter
8A and 8B are relative keys — identical notes, opposite mood. Moving between them is the one mix that changes the feel of a set without changing a single note, which is why it is the safest transition on the wheel.
A wheel can only translate a key you already have.
Be clear about which half of this is a lookup. Turning A minor into 8A is arithmetic — it needs no file, no account and no waiting, and the wheel above does it instantly. Working out that the track is in A minor is a different job entirely, and nothing on a chart can do it.
Most sites solve that by looking your track up by name in a catalogue, which works right up until the record is a promo, an edit, a bootleg, your own unreleased mix, or anything else nobody has indexed. We do it the other way round: you hand over the audio and our pipeline measures the key and the tempo from the file itself. No title to match, no metadata to trust.
Take the key it gives you, find it on the wheel above, and read off the three codes you can mix into.
Camelot key chart: all 24 codes
The whole wheel as a table. A codes are the minor keys, B codes the major keys, and the two on a row are relative keys built from the same seven notes.
| Code | Minor key | Code | Major key |
|---|---|---|---|
| 1A | A♭ minor (G♯ minor) | 1B | B major (C♭ major) |
| 2A | E♭ minor (D♯ minor) | 2B | F♯ major (G♭ major) |
| 3A | B♭ minor (A♯ minor) | 3B | D♭ major (C♯ major) |
| 4A | F minor | 4B | A♭ major (G♯ major) |
| 5A | C minor | 5B | E♭ major (D♯ major) |
| 6A | G minor | 6B | B♭ major (A♯ major) |
| 7A | D minor | 7B | F major |
| 8A | A minor | 8B | C major |
| 9A | E minor | 9B | G major |
| 10A | B minor | 10B | D major |
| 11A | F♯ minor (G♭ minor) | 11B | A major |
| 12A | D♭ minor (C♯ minor) | 12B | E major |

Camelot wheel FAQ
What is the Camelot wheel?
It's the 24 musical keys redrawn as a clock face. Each key gets a number from 1 to 12 for its position, and a letter for its mode: A for minor, B for major. A minor becomes 8A, C major becomes 8B, E minor becomes 9A. The point of the relabelling is that keys which sound good together end up next to each other, so checking whether two tracks fit becomes arithmetic instead of music theory.
Which Camelot codes mix together?
Three moves from wherever you are. Same number, other letter — 8A into 8B — swaps between relative major and minor, which share all seven notes. One number up, same letter — 8A into 9A — goes up a fifth and tends to lift the energy. One number down, same letter — 8A into 7A — goes down a fifth and settles it. The two ±1 moves change exactly one note out of seven, which is why they don't clash.
What is A minor in Camelot notation?
A minor is 8A. Its relative major, C major, is 8B — same number because they are built from the same notes, different letter because one is minor and one is major. E minor is 9A, D minor is 7A, and those two plus 8B are the three keys that mix cleanly with 8A.
Does A mean major and B mean minor?
It's the other way round, and it catches almost everyone once. A is minor, B is major. A useful way to remember it: B for bright.
How do I find the Camelot key of a song?
The wheel on this page is a lookup — it turns a key you already know into a code, instantly and without a file. If you don't know the key, that part can't be looked up: it has to be measured from the audio. Upload the MP3 or WAV to our key finder and ChordSonic's pipeline reads the key straight from the recording, along with the tempo, so you can translate it here.
Is this Camelot wheel free?
Yes — the wheel, the key-to-code translation and the compatible-key lists are completely free, with no signup and no account. Everything on this page runs in your browser. Detecting the key of an actual audio file is a separate step and has a free tier of its own.
Does the wheel work on a phone?
Yes. Tap any segment to select it. The codes are also reachable with a keyboard: tab to the wheel, then use the left and right arrow keys to move around the clock and the up and down arrows to switch between the major and minor rings.
Don't know the key? Get it from the file.
Upload an MP3 or WAV and ChordSonic reads the key and the tempo straight out of the audio — no track name to look up, no catalogue to be missing from. Then bring the key back here for its code.
