Harmonic Highlights:
- Predominant use of ii-V-I progressions firmly establishing Ab major.
- Temporary tonicization of the IV chord (Ebmaj7) via its ii-V (Fm7-Bb7).
- Distinct modulation to F major (bVI) using a Gm7-C7-Fmaj7 ii-V-I, adding harmonic color.
- Application of secondary dominants, such as C7 (V7/Fm), leading to diatonic chords.
Improvisation Focus: Navigating ii-V-I progressions across temporary modulations.
Difficulty Rating: 3 (Intermediate). The temporary modulations and secondary dominants require a solid understanding of diatonic harmony beyond basic major scales.
