- Frequent tonicization of F major (bVI in A minor) via ii-V-I progressions (Gm7-C7-Fmaj7), establishing a strong temporary tonal center.
- Use of secondary dominant F7 to Bbmaj7 (bII in A minor), suggesting a V7/IV relationship within a temporary F major context or a bluesy shift.
- Significant modulation to G major (bVII in A minor) with a clear ii-V-I progression (Am7-D7-Gmaj7), requiring careful key center tracking.
- Inclusion of F#07 as a chromatic passing diminished chord, creating tension before the Gm7 (ii of Fmaj).
Improvisation Focus: Navigating temporary tonicizations and modulations with appropriate scales and arpeggios.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent modulations and non-diatonic chords demand strong harmonic awareness beyond basic major/minor scales.
