Harmonic Highlights

  • The progression relies heavily on dominant 7th chords, including the tonic (Eb7), indicating a strong blues influence within a major key context.
  • The C7 (V7/ii) to Bb7 (V7) movement establishes a recurring non-diatonic dominant progression, creating a cyclical, blues-inflected harmonic feel.
  • A notable chromatic dominant descent (D7-Db7-C7) generates significant harmonic tension and momentum, leading back into the initial C7.

Improvisation Focus Mixolydian scales, frequently altered or shifted chromatically to match the changing dominant chords.

Difficulty Rating 4 (Advanced Intermediate) - Navigating the constant dominant chord changes and chromatic descending movements requires a solid understanding of dominant scales and their specific alterations beyond basic diatonic concepts.
