  • Harmonic Highlights:

    • Prominent backdoor dominant movement (Fm7 - Bb7) often resolving towards the tonic.
    • Frequent secondary dominant chains leading to temporary tonicizations, such as F#m7 - B7 - Emaj7.
    • Clear tonicization of the dominant (Am7 - D7 - Gmaj7) within the primary C major key.
    • Strategic use of non-diatonic dominant 7th chords (e.g., A7, Bb7) for harmonic color and voice leading.
  • Improvisation Focus: Navigating rapid chord changes and temporary tonicizations using appropriate dominant and major scales.

  • Difficulty Rating: 4 (Advanced Intermediate) - The frequent modulations and extensive use of non-diatonic harmony demand sophisticated improvisational command.
