- The progression utilizes persistent ii-V chains (Am7-D7) that alternate between G Major and its relative minor (E minor/A minor) via minor ii-V-i turnarounds (Bm7-E9#5).
- The inclusion of the C7 chord functions as a “backdoor” dominant or subdominant minor substitute, adding chromatic tension before returning to the diatonic framework.
- Frequent use of altered dominants (E9#5) and secondary dominants (A7) creates smooth chromatic voice-leading through the cycle of fourths.
Improvisation Focus Guide-tone targeting, specifically focusing on the 3rds and 7ths to navigate the rapid major and minor ii-V transitions.
Difficulty Rating 3 (Intermediate): Demands proficiency with ii-V-I patterns in both major and minor contexts and the ability to anticipate quick harmonic shifts across key centers.
