Harmonic Highlights:
- Frequent dominant 7th chords (
G7,C7) establish a strong blues sensibility within the G major key. - Numerous secondary dominants (
B7V7/Em,E7V7/Am) create temporary tonicizations and expand harmonic possibilities. - A clear chromatic dominant descent (
C7 - B7 - Bb7 - A7) adds intricate voice leading and harmonic tension. - Effective ii-V-I progressions (
Bm7 - E7 - A7) drive the harmonic movement through the cycle of fifths.
Improvisation Focus: Mixolydian mode application, adapting to each root of the frequent dominant 7th chords.
Difficulty Rating: 4 (Advanced Intermediate). The rapid and varied dominant harmonies, secondary dominants, and chromatic shifts demand quick melodic and harmonic adaptability.
