Pick a key to see its Camelot code and every key that mixes harmonically with it — visualized on a color wheel. Free — No Sign-Up
Pick a musical key to get its Camelot code and the keys that mix harmonically with it (same code, ±1, and the A/B switch).
Wheel: white outline = your key, bright = harmonically compatible, dim = the rest. Outer ring = major (B), inner ring = minor (A).
Once your set or edit is harmonically dialed in, make sure the track passes AI screening. Check it for AI-generated content and clean any artifacts before you send it to distributors or streaming platforms.
The Camelot wheel is a simplified circle of fifths that renames every musical key with an easy-to-read code — a number from 1 to 12 plus the letter A (minor) or B (major). Instead of remembering music theory, you just read the codes. This free tool maps any key to its Camelot code and back, and draws the whole wheel so you can see how keys relate at a glance.
Harmonic mixing means blending or layering tracks whose keys are compatible, so nothing clashes. On the Camelot wheel that's simple: a key mixes cleanly with the same code, the adjacent codes (+1 and −1), and its A/B switch (the relative major or minor of the same number). Pick your key and the tool highlights every compatible option for you — perfect for DJ transitions, mashups and productions that need to sit in tune.
Three steps. A few seconds.
Choose your track's musical key from the list. Not sure of the key? Detect it with our free BPM & Key finder first.
See the Camelot code for your key and watch the color wheel light up the compatible keys — bright means it mixes, dim means it doesn't.
Use the listed codes — same, ±1 and the A/B switch — to pick the next track for a smooth, in-key transition.
A clear chart, not a music-theory textbook.
Every one of the 24 major and minor keys mapped to its Camelot code, both directions, with the correct enharmonic names.
The whole Camelot wheel drawn on screen, with your key outlined and its compatible keys lit up so relationships are obvious.
One click lists every code that mixes with your key — the same code, ±1 around the wheel, and the A/B relative switch.
Works for both — outer ring for major (B) keys, inner ring for minor (A) keys, so you can mix across relative modes too.
Wherever keys need to line up.
Plan energy-lifting transitions that stay in key — pick the next track from the compatible codes and avoid clashing mixes.
Layer samples, loops and stems that share a compatible key so your arrangement sits in tune from the first bar.
Match an acapella to an instrumental by key so vocals and music blend without going out of tune.
Tag and organize a catalog by Camelot code so tracks that mix together are grouped and easy to browse.
The Camelot wheel is a mixing tool that takes the 24 musical keys — 12 major and 12 minor — and relabels each one with a short, memorable code. Instead of asking whether F minor blends with A-flat major, you glance at two codes and know instantly. Every key becomes a number from 1 to 12 paired with a letter: A for a minor key and B for a major key. So A minor is 8A, C major is 8B, G major is 9B, and so on all the way around the circle. The system was popularized by the Mixed In Key software, but the underlying idea is pure music theory dressed up in a friendlier notation.
The genius of the layout is that keys which share most of their notes end up next to each other. Because neighbouring numbers sit a perfect fifth apart, two adjacent codes have six of their seven notes in common. That heavy overlap is exactly why they sound consonant when played together, and it is what makes the wheel a reliable map for deciding which tracks will blend and which will fight.
Picture a clock face. The number on each code is the hour position, running 1 through 12 around the ring. The letter tells you which of the two rings you are on: the inner ring holds the minor keys (A) and the outer ring holds the major keys (B). Crucially, the number is shared between a minor key and its relative major — the major key built three semitones up that uses the identical set of notes. A minor and C major share every note, so both live at position 8, one as 8A and one as 8B.
Moving one number clockwise adds a sharp (or removes a flat) to the key signature; moving one number counter-clockwise does the reverse. That single-accidental step between neighbours is the whole reason the wheel works. To get any track onto the wheel you first need its key — you can read it off a DAW, a purchased track's metadata, or detect it in seconds with our free BPM & Key finder and then look up the matching code in the converter above.
Harmonic mixing boils down to a handful of moves you can make from any starting code without the keys clashing. These are the rules the tool applies for you when it highlights compatible keys:
Stick to these moves and consecutive tracks will always share enough notes to blend. Break them and you risk a dissonant collision where two melodies grind against each other in the crossfade.
When two tracks overlap during a transition, their basslines, chords and melodic hooks are momentarily sounding at the same time. If the keys are compatible, the notes reinforce one another and the ear hears a single, richer piece of music. If the keys clash, the same overlap produces beating, muddiness and a distinct feeling that something is "off," even to listeners who could never name a key. Harmonic mixing removes that friction so the crossfade feels intentional rather than accidental.
This is why key matching matters most during longer blends — the more bars two tracks share, the more a key clash has time to expose itself. Short cuts on the drop can sometimes get away with a mismatch, but any sustained layering rewards you for planning around the wheel.
The wheel is only as good as the key data you feed it, so accurate detection comes first. Producer-made tracks usually carry a known key from the DAW, but downloads, samples and acapellas often do not. Rather than guessing, run the file through our browser-based BPM & Key finder, which returns the detected key, the Camelot code and the tempo. From there you drop the key into the converter above and read off the compatible codes.
If you only want to mix a specific section — an intro, a vocal phrase, a drop — trim it down first with our free audio cutter so you are analysing and layering only the part that matters. Clean source material in, clean harmonic decisions out.
A great DJ set is a journey, and the wheel doubles as an energy map. Staying on the same number or moving by a single step keeps energy steady, which is ideal for a warm-up or a long, hypnotic middle section. When you want to lift the room, the +2 move raises the intensity without leaving the harmonic family. Sprinkling in the A/B switch lets you slide between the brightness of major keys and the tension of minor keys to control mood.
Plan a set as a path around the wheel: a sequence such as 8A, 9A, 9B, 10B, 10A traces small compatible steps while gradually shifting colour and lifting energy. Because every hop is legal on the wheel, the whole arc stays in key even as the feel evolves from track to track.
Mashups are where key matching becomes non-negotiable, because an acapella and an instrumental play in full simultaneously for the entire song rather than for a few transition bars. Match their Camelot codes — same code or the A/B switch is safest for vocals — and the voice sits naturally on the new backing. If they are a step or two apart, pitch-shifting one element into the other's key (many DJ tools do this without altering tempo) brings them into line.
The most common mistakes are easy to avoid once you know them:
The Camelot wheel is really the circle of fifths in disguise. Musicians have used the circle for centuries: it arranges the 12 major keys so each neighbour is a perfect fifth away, with the relative minors nested inside. Camelot notation simply rotates that circle so C major lands at 12 o'clock-equivalent position 8, then swaps the key names for numbers and the words "major/minor" for the letters B and A. Everything the circle of fifths tells a composer about closely related keys, the Camelot wheel tells a DJ about compatible tracks — it is the same theory made instantly readable at the decks.
Once your set or edit is harmonically dialled in, the last step is making sure the track itself is release-ready. Run it through our AI Checker to confirm it passes AI screening, use the AI Cleaner to remove any artifacts, and see the pricing plans when you are ready to process at scale.
