  • Harmonic Highlights

    • Prominent use of chromatic passing diminished chords (F#07, G#07), creating a smooth, ascending bassline movement within the opening progression.
    • Clear modulation from Bb major to the distant key of Db major via successive ii-V-I progressions (e.g., Ebm7 - Ab7 - Dbmaj7).
    • Extended ii-V-I chains, such as Fm7 - Bb7 - Ebm7 - Ab7 - Dbmaj7, demonstrate sophisticated dominant cycling leading to the Db major resolution.
  • Improvisation Focus Arpeggio superimposition over ii-V-I progressions across multiple key centers.

  • Difficulty Rating 4 (Advanced Intermediate) - The frequent modulations to distant keys and the chromatic passing chords require advanced harmonic understanding and agile navigation.
