Harmonic Highlights:
- Frequent use of the I7 chord (Ab7/C) providing a dominant function leading to the IV (Db).
- Prominent application of the #IVdim7 (D07), often resolving deceptively back to IV (Db) or as a passing diminished.
- Standard ii-V-I and vi-ii-V-I progressions in Ab major form the foundational harmonic movement.
Improvisation Focus: Diminished scale application over the D07 chord.
Difficulty Rating: 3 (Intermediate). The frequent use of passing diminished chords and I7-IV movements elevates it beyond basic diatonic harmony.
