Harmonic Highlights
- The opening employs
G7sus-Cmaj7repeatedly, establishing C major through a soft, modal Vsus-I resolution. - An extended
iii-VI-ii-Vprogression (Em7 - A7 - Dm7 - G7sus) leads back to the tonic, preceded by the chromaticF#m7b5 - Fm7for added tension and color. - A bold modulation to Ab major (bVI) is introduced through
Abmaj7 - Eb7, a characteristic movement to a distant major key.
Improvisation Focus Chord-scale theory with emphasis on arpeggio outlining across modulations.
Difficulty Rating 4 (Advanced Intermediate) - Requires navigating key center shifts, temporary tonicizations, and chromatic chord progressions beyond basic diatonic harmony.
