Harmonic Highlights:
- Features a C7b9 secondary dominant (V7/ii), adding altered tension before the Fm7-Bb7-Ebmaj7 progression.
- Repeated and foundational ii-V-I progressions (Fm7-Bb7-Ebmaj7) establish the tonal center.
- Incorporates Eb7 (I7) as a secondary dominant (V7/IV) leading to the subdominant Abmaj7.
- Utilizes an Abm7-Db7 (minor ii-V of Gb) serving as a “backdoor” dominant progression resolving to the tonic Ebmaj7.
Improvisation Focus: Targeting chord tones and arpeggios over ii-V-I progressions, with awareness of secondary dominant alterations.
Difficulty Rating: 3 (Intermediate) – The piece features standard forms with common secondary dominants and a backdoor progression, requiring moderate harmonic awareness.
