Harmonic Highlights:
- A characteristic chromatic approach to the tonic minor is established from
Em11toEbm11. - A clear
ii-V-Iprogression (C#m7-F#7-Bmaj7) leads to an unexpected, albeit brief, modulation to B major. - The progression features a subsequent
iiø7-V7-iintoAbm7(Bbm7b5-Eb7b9-Abm7), the subdominant minor of Eb, alongside frequent altered and extended dominant chords.
Improvisation Focus: Navigating temporary modulations with appropriate modal and altered dominant scales.
Difficulty Rating: 4 (Intermediate-Advanced). The frequent modulations to distant keys and the extensive use of altered and extended dominant chords require sophisticated harmonic understanding.
