  • The opening iiø7-V7alt progression (Am7b5-D7#5) strongly implies G minor but frequently resolves deceptively into dominant chains rather than a stable G minor tonic.
  • Frequent dominant cycling, such as G9-C7, facilitates rapid modulations, moving the harmonic progression from implied G minor towards F major and Bb major sections.
  • The harmony actively alternates between the initial G minor implications and clearly established related major keys (F major, Bb major) through standard V-I and ii-V-I progressions.

Improvisation Focus: Navigating arpeggios and altered scales across constantly shifting tonal centers and deceptive resolutions.

Difficulty Rating: 4 (Advanced Intermediate). Requires advanced harmonic understanding to follow the frequent modulations and deceptive resolutions across multiple key centers.
