12B = E Major

12B is the Camelot code for E major. It sits at position 12 on the outer, major (B) ring; in Traktor's Open Key notation it's 5d. Below: every key that mixes with 12B, the energy moves out of it, and the wheel set to it.

Hover or tap any key — the wheel shows the four safe moves out of it. Green is the same key, cyan a ±1 step, violet the major/minor flip, amber a +2 energy lift.

What Keys Mix With 12B?

Every key the SetFlow engine scores as compatible with 12B (E major), highest first. Anything scoring 60 or above is a safe mix; the verdict column tells you what the move does to the set.

The top-scoring move out of 12B is 1B (B major) at 90/100. Moving up Camelot wheel — energy lift.

Raising the Energy From 12B

Three moves out of 12B build energy without breaking key compatibility:

  • 12B → 1B (B major) — One step up the wheel — a near-invisible lift that keeps the set moving forward.
  • 12B → 12A (D♭ minor) — The relative minor — same notes, darker and more driving.
  • 12B → 1A (A♭ minor) — One step up and a ring flip — a lift and a mood change in a single move.

For a bigger, more noticeable lift at a peak moment, jump +2 to 2B (F♯ major). Use it sparingly — anything further round the wheel starts to clash.

Frequently Asked Questions

What key is 12B in music?

12B on the Camelot wheel is E major. The number 12 is its position on the wheel and the letter B means it sits on the outer, major ring. In Traktor's Open Key notation the same key is written 5d.

What keys mix with 12B?

From 12B (E major) the safe moves are: staying in 12B, stepping to 11B (A major) or 1B (B major), flipping to 12A (D♭ minor, the relative minor), and jumping to 2B (F♯ major) for an energy lift. Anything further round the wheel risks an audible clash.

What is the energy boost key from 12B?

The classic +2 energy boost from 12B is 2B (F♯ major) — two steps up the wheel on the same ring. For a gentler build, step +1 to 1B (B major) instead; it lifts the set without the audience noticing the key change.

Is 12B a minor or major key?

12B is major — every B code sits on the outer ring of the Camelot wheel. Its relative minor is 12A (D♭ minor): both keys share the same notes, which is why flipping between them always mixes cleanly.
