Harmonic Highlights
- Frequent deployment of diatonic I-vi-ii-V progressions firmly establishing C major.
- Strategic use of secondary dominants (C7 leading to Fmaj7, E7b13 to Am7) to extend harmonic movement.
- The iiø-V-i progression (Em7b5-A7b9-Dm7) temporarily tonicizes the D minor chord, the supertonic.
- Chromatic embellishments like Eb07 and E7b13 add color and require precise harmonic anticipation.
Improvisation Focus Navigating various ii-V-I progressions and their extensions, including secondary dominants and minor ii-V-i forms.
Difficulty Rating 3 (Intermediate) - The blend of common diatonic changes with secondary dominants and chromatic alterations demands moderate harmonic fluency.
