Harmonic Highlights:
- The opening features distinctive parallel major 6th chords (D6-G6, then Eb6-Ab6), often moving by root P4 or chromatically, creating a characteristic ‘floating’ sound.
- Brief but clear excursions occur, such as F7-Bb6, functioning as a V7-I in the key of Bb major (the subdominant of F).
- The G7-C6 progression provides a strong V/V - V harmonic motion, serving as a robust dominant preparation for the implied return to the tonic F major.
Improvisation Focus: Navigating the arpeggios and major scales corresponding to the frequently shifting parallel 6th chords.
Difficulty Rating: 4 (Advanced). The frequent chromatic shifts and non-diatonic major 6th chord progressions demand acute harmonic awareness and quick adaptation from the improviser.
