Harmonic Highlights
- The Em7-A7 progression introduces a deceptive ii-V (of D) often resolving back to Bb, creating a ‘backdoor’ dominant effect or momentary ambiguity.
- A strong Dm7-G7-Cm7-F7 chain establishes a progression of secondary ii-Vs (V/ii-V/V, then ii-V) effectively navigating towards the tonic.
- The Ebm6 chord provides modal interchange (bIVm6), adding a distinctive, introspective color before resolving to the tonic.
- C7 functions as a secondary dominant (V/V), reinforcing the impending dominant F7 and the eventual resolution to Bb.
Improvisation Focus: Precise arpeggio outlining and navigating common ii-V cycles.
Difficulty Rating: 3 (Intermediate). The tune features both standard ii-V-I progressions and some non-diatonic chords like Ebm6 and secondary dominants requiring attentive harmonic navigation.
