The "engine" of a G7 is the tritone between its 3rd (B) and 7th (F). A Db7 uses these same two notes (the 3rd is F, the 7th is Cb/B), creating a smooth, chromatic bass descent to the target chord. 3. Secondary Dominants
This involves "borrowing" chords from a parallel mode, usually the parallel minor.
This builds immense tension, as the listener waits for the bass to finally move and "resolve" the shifting harmonies above it. Summary Tips
Apply this to a Tritone Sub. Instead of just Db7, use Abm7 — Db7 — C . 7. Pedal Points
