Harmonic Highlights
- Frequent use of the V7b9 dominant (D7b9) consistently resolving to the G minor tonic, defining the minor key.
- The A7b9 chord functions as a V7/V, creating a secondary dominant that targets the D7b9 before returning to the home key’s dominant.
- A clear II-V-I progression in the relative major (Cm7-F7-Bbmaj7), indicating temporary tonicization of Bb major.
- The B07 chord acts as a passing diminished or viio7/Cm, effectively leading into the Cm7 within the relative major’s progression.
Improvisation Focus G melodic minor scale and its derived modes (e.g., Altered Scale for D7b9).
Difficulty Rating 3 (Intermediate) - The tune incorporates standard minor key harmony, secondary dominants, and a relative major II-V-I, requiring a solid grasp of minor scale applications.
