Harmonic Highlights:
- Features a non-diatonic C7 (IV7) after the Gmaj7, creating a bluesy or substitute dominant flavor rather than a strict diatonic progression.
- Employs a chromatic Bb07 (bIIIdim7) as an effective passing diminished chord, facilitating smooth voice leading between Bm7 (iii) and Am7 (ii).
- Showcases a chain of secondary dominants (A7, E7, B7) and their related ii-V progressions, generating strong harmonic motion and temporary modulations.
Improvisation Focus: Adapting scales and arpeggios to temporary key centers, particularly employing Mixolydian and altered dominant sounds over V7 chords.
Difficulty Rating: 3.5 (Intermediate to Advanced). The frequent secondary dominants, chromatic passing chords, and non-diatonic harmonies require careful navigation beyond basic diatonic playing.
