4B = A♭ Major

4B is the Camelot code for A♭ major. It sits at position 4 on the outer, major (B) ring; in Traktor's Open Key notation it's 9d. Below: every key that mixes with 4B, 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 4B?

Every key the SetFlow engine scores as compatible with 4B (A♭ 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 4B is 3B (D♭ major) at 90/100. Moving down Camelot wheel — energy drop.

Raising the Energy From 4B

Three moves out of 4B build energy without breaking key compatibility:

  • 4B → 5B (E♭ major) — One step up the wheel — a near-invisible lift that keeps the set moving forward.
  • 4B → 4A (F minor) — The relative minor — same notes, darker and more driving.
  • 4B → 5A (C 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 6B (B♭ major). Use it sparingly — anything further round the wheel starts to clash.

Frequently Asked Questions

What key is 4B in music?

4B on the Camelot wheel is A♭ major. The number 4 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 9d.

What keys mix with 4B?

From 4B (A♭ major) the safe moves are: staying in 4B, stepping to 3B (D♭ major) or 5B (E♭ major), flipping to 4A (F minor, the relative minor), and jumping to 6B (B♭ major) for an energy lift. Anything further round the wheel risks an audible clash.

What is the energy boost key from 4B?

The classic +2 energy boost from 4B is 6B (B♭ major) — two steps up the wheel on the same ring. For a gentler build, step +1 to 5B (E♭ major) instead; it lifts the set without the audience noticing the key change.

Is 4B a minor or major key?

4B is major — every B code sits on the outer ring of the Camelot wheel. Its relative minor is 4A (F minor): both keys share the same notes, which is why flipping between them always mixes cleanly.
