Harmonic Highlights
- The progression Cmaj7 - F7#11 - G6 features a characteristic ‘backdoor’ resolution using a #11 bVII7 dominant to the tonic.
- A compelling descending chromatic dominant sequence (G7 - Gb7 - F7 - E7) creates significant tension before resolving to a V/V (A7).
- The inclusion of Eb7 (bVI7) introduces chromatic mediant harmony, functioning as a colorful tension chord or a tritone substitution.
Improvisation Focus Applying altered scales over the numerous dominant 7th chords and navigating chromatic guide tones.
Difficulty Rating 4 (Advanced Intermediate) - The extensive use of chromatic dominants, tritone substitutions, and altered harmonies requires sophisticated harmonic understanding and melodic navigation.
