Harmonic Highlights:
- Initial Amaj/E and Dmaj/E chords over a sustained E bass create a unique suspended or pedal tone feel, blurring simple I and IV functions in A major.
- A clear Imaj7-IVmaj7-Imaj7 progression firmly establishes the A major key center before unexpected deviations.
- An abrupt chromatic modulation occurs, moving from A major to C major through a series of descending major chords by perfect fourth/fifth (Cmaj7-Fmaj7-Bbmaj7).
- The subsequent Dm7-G7-Cmaj7 progression solidifies the new C major key center with a classic II-V-I turnaround.
Improvisation Focus: Adapting major scales and arpeggios to rapidly shifting, often distantly related, key centers.
Difficulty Rating: 4 (Advanced). The frequent and often unexpected chromatic modulations demand quick harmonic recognition and versatile melodic navigation.
