Mixing from 1B to 1A

How to mix this transition

Blend over 16–32 bars to let the minor tonality settle without sounding abrupt. Bring the incoming track in during a phrase boundary or after a kick swap, allowing the new minor melody or chord voicing to establish itself before the outgoing major-key elements fully fade. Use a high-pass filter on the incoming track's low end during the overlap to avoid harmonic mud—the relative relationship means both keys share overtones, and stacking them carelessly clouds the shift. Watch the bass line: if the outgoing track emphasizes the major third or dominant, ride the EQ to soften those frequencies as the minor tonality takes over.
