Leave the key intentionally
Use secondary dominants, modal interchange, chromatic mediants and modulation to change harmonic direction.
Borrow, redirect and reshape harmony with a reason.
The final stage is about options and explanation. Advanced colours are connected to voice leading, target chords and tonal centres so that substitutions and altered sounds remain musical decisions, not disconnected tricks.

Handle dominant tension
Understand tritone substitution, altered dominants, whole-tone and diminished resources.
Analyse and create
