Harmonic Highlights

  • The progression repeatedly employs a classic iiø7-V7b9-i minor resolution (F#m7b5 - B7b9 - Em7), firmly establishing the E minor tonic.
  • A strong pull to the relative major is evident with the Am7 - D7 progression, functioning as a ii-V in G major, often resolving back to Em, creating harmonic tension and release.
  • The sequence Em7/D - Cmaj7 - Bm7 - Gmaj7 features a characteristic descending bass line (E-D-C) and incorporates Cmaj7 (bVI), indicating modal interchange or a natural minor influence.

Improvisation Focus Navigating the minor ii-V-i progression using E minor Dorian and Harmonic Minor scales.

Difficulty Rating 3 - Intermediate. The minor key ii-V changes and relative major modulations require a solid understanding of minor harmony and altered dominant voicings.
