Harmonic Highlights
- The initial Em9-Bm9 progression strongly establishes B minor as a primary tonal center, functioning as a repeated iv-i relationship.
- A significant chromatic modulation occurs via Am7-D7, leading to a prolonged Bbmaj9, creating a temporary and remote tonal area.
- The extended Bbmaj9 section serves as a stark harmonic contrast, acting as a temporary, non-diatonic tonic unrelated to B major/minor.
- The A9sus chord functions as a bVII dominant, providing a modal turnaround resolving effectively to the Bm9 tonic.
Improvisation Focus B Dorian scale, adapting to the shifts.
Difficulty Rating 4 (Intermediate-Advanced). The frequent, remote modulations and sustained non-diatonic chords demand significant harmonic awareness and adaptability.
