Harmonic Highlights:
- Frequent use of secondary dominants (e.g., C7 to Fmaj7, D7 to Gm7).
- Temporary tonicization of related keys, notably F major (C7-Fmaj7 sequence).
- Chromatic descending motion with minor chords (Am7-Abm7-Gm7) creating smooth voice leading.
- Extended dominant cycles (A7-D7-G7) build tension leading to the G minor tonic.
Improvisation Focus: Navigating functional harmony with strong dominant chord tone and altered scale emphasis.
Difficulty Rating: 4 (Advanced) because it features numerous temporary modulations, extended dominant cycles, and chromatic passing chords requiring precise harmonic understanding.
