Mixing from 4B to 3B

How to mix this transition

Since both keys are major and sit one step counter-clockwise on the wheel, use a 16–32 bar blend to let the harmonic shift breathe naturally. Bring in the incoming track's kick and bass around a phrase boundary in the outgoing track, then use a high-pass filter or gentle EQ kill on the old track's mids to avoid muddiness as the new key's fundamentals emerge. Avoid stacking this transition on a BPM change; keep tempo locked so the audience feels the key drop, not a tempo shock. The move works best when you're already in a major-key section—jumping from a minor or sparse breakdown into this transition can feel disconnected.
