Mixing from 6B to 9B

How to mix this transition

Because this is a parallel-key upper (same letter, +3 on the wheel), the harmonic palettes diverge completely—there's no shared key signature to lean on. Plan a 16–32 bar blend minimum to let the new key's brightness establish itself without jarring the floor. Use a high-pass filter kill on the outgoing track's low end around bar 8–12 of the blend to reduce harmonic mud; bring the new track's kick and bass in cleanly on a phrase boundary, ideally after a 4- or 8-bar breakdown in the outgoing track. Avoid stacking this tonal shift with a BPM change or a simultaneous energy drop—the key change alone is doing heavy lifting. EQ the incoming track's mids up slightly to help the G Major tonality cut through during the blend window.
