Harmonic Highlights

  • The progression employs chromatic parallel movement and tritone substitutions, notably the Eb7/Db acting as a substitute dominant resolving toward D minor.
  • The opening Fmaj7 to Eb7/F (subV/V) creates a sophisticated Lydian dominant tension that reinforces the F major tonality before pivoting to the D minor relative.
  • Structural stability is maintained through frequent minor ii-V-i sequences (Em7b5 โ€“ A7b9 โ€“ Dm7), utilizing dominant pedal points like Em7b5/A to create tension.
  • Secondary dominants, such as G7 (V/V), are used to approach the Gm7 (ii), adding temporary major-key brightness to a predominantly minor-harmonic landscape.

Improvisation Focus D Harmonic Minor and D Melodic Minor scales to navigate the frequent ii-V-i resolutions and chromatic altered dominants.

Difficulty Rating 3 (Intermediate): While the tempo is usually slow, the dense chromaticism and slash-chord inversions require precise guide-tone navigation and awareness of shifting tonalities.
