Harmonic Highlights:
- Frequent use of parallel minor (Ebm7) within an Eb major context, creating a somber yet fluid transition.
- A distinctive modulation via
Abm7-Db7alttoGbmaj7, a ii-V-I in Gb major, abruptly shifting the tonal center a minor third up before returning. - Chromatic bass movement under sustained harmony (e.g.,
F7/Eb, Emaj7/Eb) generating unique voicings and extended harmonic colors. - Standard ii-V-I progressions are frequently embellished with altered dominant chords (e.g.,
Bb7alt,Db7alt), demanding specific scale choices.
Improvisation Focus: Navigating the shifting key centers and employing appropriate altered scales over dominant chords.
Difficulty Rating: 4 (Advanced Intermediate) The frequent modulations and altered dominant voicings require a strong harmonic ear and mastery of various scales.
