What mixes with 7A

Every key below shares enough notes with D minor to hold a blend. The wheel is ordered so neighbours are related, not so numbers are: 7A sits one step from 8A and 6A, and directly across the letter from 7B.

What clashes

Distance on the wheel is dissonance. Put 12A under 7A and the two tracks disagree about which notes are in the key — a sour, unsettled sound that no amount of EQ fixes. Anything three or more steps away on the same letter does it.

The notes in D minor

Seven notes, one of each letter. Two keys mix when these sets overlap: 7A and 7B contain exactly the same seven, which is why the relative move is free.

The loop the trainer plays in 7A

Four bars, one chord each — the same progression in every key and every genre, so the only thing that changes when you move round the wheel is the key itself. That is the whole point: it trains the ear on the move, not on the track.

Questions

What key is Camelot 7A?
7A is D minor, written Dm. In Open Key notation — Traktor, Beatport — the same key is 12m.
What keys mix with 7A?
7B, 8A, 6A are the safe moves: the relative major, and one step either way round the wheel. 7A under 7A is free, of course. 9A and 5A are the two-step energy moves — bigger lift, bigger drop, still harmonically sound.
Which keys clash with 7A?
Anything more than two steps away on the same letter. 12A is the classic example: 5 steps away. The two tracks fight — this is the sound you’re learning to avoid.
