What this transition feels like

Moving from 1A (A♭ Minor) to 1B (B Major) swaps minor melancholy for major brightness while keeping the same key signature (seven flats). The audience hears the mood lift—minor tension dissolves into major resolution—but the harmonic foundation remains familiar. Energy stays level; the shift is purely tonal and emotional rather than propulsive.

How to mix this transition

Blend over 16–32 bars to let the modal colour gradually replace the original mood. Start the incoming track's intro or breakdown section to avoid stacking the tonal flip on top of a rhythmic peak. Use a high-pass filter sweep on the outgoing track during the blend to soften the minor tonality as the major chords enter; this masks the transition and prevents harmonic clash. Watch for vocal or melodic hooks that anchor the original key—if the outgoing track's melody is strongly minor-centric, extend the blend or drop it out entirely during the crossfade.

Common mistakes

Don't flip the mode during a kick or bass drop—blend through a quieter section
Don't ignore the outgoing track's melody; a minor hook will fight the incoming major tonality
Don't rush the blend; 16 bars minimum prevents the mood shift from feeling jarring
