  • The initial Eb6 - Eb7 movement introduces a bluesy flavor, often anticipating the IV chord or adding a dominant quality to the tonic.
  • A clear tonicization of the iii minor occurs through the Am7b5 - D7b9 - Gm7 (ii-V-i in G minor) progression.
  • The Abm6 (iv minor) chord provides a distinct modal interchange or minor color, adding harmonic richness to the Eb major key.
  • Gb7 functions as a chromatic dominant, creating tension before the Fm7 - Bb7 (ii-V) progression.

Improvisation Focus: Navigating temporary tonicizations and modal interchange scales.

Difficulty Rating: 4/5. It requires understanding of secondary dominants, modal interchange, and executing ii-V-i progressions in minor keys.
