Harmonic Highlights
- Employs classic ii-V-I progressions in F major and frequently tonicizes the IV chord (Bb major) via ii-V.
- Prominent use of altered dominants (C7#5, F7#5, C7b9) to heighten tension and drive resolution.
- Features a chromatic shift from IVmaj9 to iv minor (Bbmaj9 to Bbm9) creating a lead-in to the V chord.
- Includes instances of tritone substitution (Db7 for G7) and descending chromatic dominant sequences.
Improvisation Focus Targeting chord tones and extensions, especially altered scales (e.g., Altered, Lydian Dominant) over the frequent altered dominant chords.
Difficulty Rating 4 (Advanced Intermediate). The complex altered dominants, temporary modulations, and chromatic movements demand a sophisticated harmonic ear and technique.
