Harmonic mixing and Camelot keys

Harmonic mixing means choosing records whose keys work together. Two records can match in tempo and still clash: when their keys don't sit together, the basslines and chords fight during the blend, and the mix sounds sour even with the kicks in time. The Camelot wheel gives every key a short code, so you can see which records fit.

Keys in a minute

Every key has a home note and a set of notes that belong to it. Each major key shares all of its notes with one minor key, its relative minor: C major and A minor use the same seven notes. The more notes two keys share, the more at home they sound together.

The Camelot wheel

Key names are hard to compare in the middle of a mix. The Camelot wheel gives every key a number from 1 to 12 and a letter: A for minor, B for major. Neighbors on the wheel share all but one note. A minor is 8A, and C major, its relative major, is 8B.

Moves that sound smooth

The same code. 8A to 8A. The safest blend there is.
One step around the wheel. 8A to 7A or 9A. A gentle change.
Minor to major on the same number. 8A to 8B. The same notes, a brighter mood, and back the other way for a darker one.

Moves for a lift

Two well-known moves change the energy on purpose:

Two steps around, 8A to 10A. That's a whole step up. You'll notice it, and it lifts.
Seven steps around, 8A to 3A. That's a half step up, like the key change near the end of a pop song. Keep the blend short and clean.

When keys don't fit

Sometimes you'll want a record that clashes, and you can still play it:

Keep the blend short, and make the change on a phrase.
Swap the low end: take the bass out of one record before you bring the other's in, so the basslines never overlap.
Blend on drums: bring the new record in over a stretch of the old one with no bassline or chords.
Or lean into it. A hard key change at the top of a phrase can be a statement.

Trust your ears

Key detection is a guide, not a fact. It sometimes mixes up a minor key and its relative major, and a track can change key partway through. If a blend sounds right, it is. Speed matters too: on a turntable, a record played about 6% faster is a half step sharp, so a big tempo change can take a record out of a key that fit.

Keys in Mix//Sync

Every track shows its key as a Camelot code, under the track name on the deck and in your library. Fits with, the row of records under each deck, favors records in the same key, one step around the wheel, or the relative major or minor.
