Harmonic Highlights:
- Prominent use of secondary ii-V progressions, such as Bm7b5-E7b9 leading to Am7 (iv), and C#m7b5-F#7b9 (ii-V to v minor).
- Non-diatonic Gmaj7-C7 introductory phrase, creating a distinct “backdoor” dominant feel or momentary shift from the E minor tonic.
- Employs a chain of dominants (A7-D7) leading to Gmaj7 (bIIImaj7), indicating a brief modulation to the relative major.
Improvisation Focus: Targeting chord tones and characteristic scales for each secondary ii-V progression.
Difficulty Rating: 4. Its frequent modulations, secondary ii-V progressions, and chromatic alterations demand precise harmonic understanding.
