Harmonic Highlights

  • Prominent use of secondary ii-V-I progressions (e.g., Bm7b5-E7b9 to Am7, Gm7-C7 to Fmaj7) to momentarily tonicize non-tonic chords.
  • An extended cycle of ii-V and dominant 7th chords (Em7-A7-D7-Dm7-G7) creating a strong, multi-stage resolution to the tonic.
  • The Bb7#11 chord introduces a colorful Lydian Dominant sound, functioning as a chromatic dominant or tritone substitution within the progression.

Improvisation Focus Chord tone targeting and outlining ii-V-I progressions.

Difficulty Rating 4 (Advanced Intermediate) - The rapid succession of complex ii-V and dominant cycles, along with chromatic chords, demands quick harmonic navigation.
