Harmonic Highlights

  • The opening employs a G7b13/B to Cm11 movement, creating a deceptive resolution that delays the arrival of the D major tonic.
  • Extensive use of slash chords (Fm9/Bb, Em7/A) facilitates a “floating” harmonic texture, obscuring traditional functional cadences in favor of modal color.
  • The structure features rapid modulations to distant centers like F# major and F major via non-diatonic ii-V sequences, requiring precise horizontal navigation.

Improvisation Focus Navigating shifting tonal centers by applying Melodic Minor modes (Altered and Lydian Dominant) over the frequent non-diatonic ii-V patterns.

Difficulty Rating 4/5: The sophisticated modulations and non-functional slash chords demand advanced harmonic awareness and the ability to connect distant keys fluently.
