  • Frequent iiø-V7-i progressions in F minor, including a strong Gm7b5-C7b9-Fm6 resolution.
  • Prominent use of Dbmaj7 (bVI) as a temporary tonal center, often reached via a V7-I progression (Ab13b9 to Dbmaj7).
  • Striking chromatic major 7th shifts, such as Amaj7 preceding Ab13b9 and the descending Emaj7-Ebmaj7.
  • Strategic modal interchange evident in the alternation between F minor (Fm6) and F major (Fmaj7) resolutions.

Improvisation Focus: F Harmonic Minor scale.

Difficulty Rating: 4 (Advanced) The frequent modulations, altered dominants, and modal shifts require advanced harmonic understanding and improvisational flexibility.
