Harmonic Highlights

  • The opening uses a tonic pedal point (C/G, G9sus) to create a pastoral, suspended harmonic environment before resolving to the home key.
  • The transition from Eb13 to Abmaj7 utilizes a bIII-bVI motion, introducing chromatic mediant relationships that briefly pull the listener away from the C major center.
  • Extensive use of secondary dominants (D13) and altered dominant tensions (G7#5#9) facilitates smooth voice leading into standard ii-V-I cycles.

Improvisation Focus Navigating modal interchange and chromatic shifts while maintaining C major diatonic reference points.

Difficulty Rating 3/5 โ€” While the primary key is stable, the non-diatonic movements and frequent dominant extensions require intermediate harmonic navigation skills.
