Mixing from 3B to 3A

How to mix this transition

Blend over 16–32 bars to let the minor tonality establish itself without sounding abrupt. Bring the incoming track in on a phrase boundary, ideally after a breakdown or at the start of a new 8-bar section in the outgoing track. Use a high-pass filter on the incoming track's low end during the first 8 bars to avoid mud as the two harmonic centers coexist, then open it fully once the major track has faded. The shared key signature means you can layer both tracks briefly without dissonance—exploit this window to build a smooth handoff rather than a hard cut.
