- The progression frequently features chromatic diminished chords (e.g., G#07, Bb07) acting as passing chords resolving chromatically to diatonic chords or leading to functional harmony.
- Classic ii-V-I progressions (Am7-D7-G) serve as foundational movements within the primary key of G major.
- Secondary dominant chords (e.g., E7 as V/ii leading to Am7; G7 as V/IV leading to C) temporarily tonicize diatonic chords, adding harmonic interest.
Improvisation Focus: Emphasizing chord tones and adapting to secondary dominants and chromatic passing chords within the G Major tonality.
Difficulty Rating: 3/5. It combines fundamental diatonic harmony with common chromatic passing chords and secondary dominants, requiring a moderate understanding of functional harmony beyond simple scale usage.
