Energy boost
The energy boost is the +2 move on the Camelot wheel — two positions clockwise, same letter — which lifts a mix by a whole tone. Every chart lists it as a legal move, and it is the one DJs reach for least.
Measured in our catalog
Across 7,243 transitions sequenced by hand here, the +2 energy boost appears in 2.29% — against 4.79% expected by chance. DJs use it at 0.48× the rate a shuffled running order would.
The comparison is what makes that readable. Every other textbook move is used far above chance — the four standard ones together run at 70.5% against 18.3%, 3.8× — so the +2 is not merely unpopular, it is the only taught move that DJs avoid on purpose.

Why it matters
The theory behind it is sound. Two steps clockwise raises the key a whole tone, which is the same trick a pop record uses when the last chorus modulates upward, and on paper it is the move that adds lift without leaving the wheel.
What DJs do with it is a different question from what the chart permits, and it is worth knowing the answer before you build a set around it. A move being legal is not evidence anybody wants to hear it.
Frequently asked
What is a +2 mix in Camelot?+
Moving two positions clockwise while staying on the same letter — 8A to 10A, for instance. It raises the key by a whole tone, which is where the "energy boost" name comes from.
Does the energy boost actually work?+
It is harmonically defensible and rarely used. In 7,243 transitions sequenced by hand here it appears 2.29% of the time against 4.79% by chance — so DJs choose it less often than a shuffle would.
How do you raise the energy of a set without a +2?+
By tempo and by track choice rather than by key. Across the same sets, energy climbs from 55 on the opening track to 63 in the last third, and the running order does that work without leaving the key.
Related terms
Camelot key
Camelot notation renames every musical key as a number from 1 to 12 plus a letter — A for minor, B for major. 8A is A minor. Codes next to each other on the wheel share most of their notes.
Harmonic mixing
Harmonic mixing means choosing the next track by key as well as tempo — staying on the same Camelot code, moving one step around the wheel, or swapping between the major and minor of the same number.
Tonal shift
A tonal shift moves one position around the Camelot wheel and switches between major and minor at the same time — 8A to 9B, say. No standard chart lists it, and it is the most common rule-break DJs make.
Energy curve
An energy curve is the shape a set makes over time — where it starts, how steeply it climbs, where it peaks. It is the plan behind a running order, and the thing a crowd feels without being able to name.
