Mixing from 1B to 7B

How to mix this transition

Bring in the new track (7B, F Major) at a phrase boundary—never mid-bar—to maximize the shock value and give the audience a clear reset point. Use a hard EQ kill on the outgoing track's mids and highs 4–8 bars before the swap to strip away harmonic detail, then flip the crossfader or cut the channel abruptly rather than blending over 16 bars; a 2–4 bar overlap at most, riding the bass frequencies to anchor continuity. The tritone interval itself will create dissonance if both tracks' fundamentals ring together, so either kill the low end of the outgoing track or delay the new track's kick by a beat or two. Avoid stacking this move on a BPM change or a breakdown—the harmonic shock is already extreme.
