Mixes harmonically
9B → 8B · 10B · 9AFrom 9B, 10B (D major) lifts the energy a step; 9A (E minor) settles into the relative minor; 8B (C major) cools the energy down a step.
How to mix it
In 9B at 128 BPM: 10B (D major) — move to 10B to push the floor harder; 9A (E minor) — switch to 9A for a mood change without losing the groove; 8B (C major) — drop to 8B to bring the room down gently.
Pitch range at ±6%: 120-136 BPM — anything in that window beatmatches without sounding stretched.
Key on the fader: without key lock (Master Tempo on CDJs), above roughly +5% it plays a semitone higher, so treat it as 4B rather than 9B; below -5% it reads as 2B. With key lock on, it stays 9B across the whole range.
Programming: a peak-time weapon — save it for the main stretch (energy 85/100).
