- The progression frequently establishes and departs from D major, notably featuring a clear ii-V-I to E major (
F#m7, B7, Emaj7). - Employs tritone substitutions, such as
F7#11(sub for B7 leading to E minor/major) andBb7(sub for E7), adding altered dominant color and unexpected resolutions. - Features non-diatonic root movements and a sequence like
F7#11, Cmaj7/E, Fmaj7, creating significant shifts away from the implied A major key center.
Improvisation Focus: Dynamic application of chord-scales and altered dominant concepts across rapid modulations.
Difficulty Rating: 4 (Advanced). Frequent, non-diatonic modulations and chromatic substitutions require advanced harmonic understanding and agile navigation.
