Example8 Contrary motion through changes

We’re revisiting the ascending/descending seesaw idea that we first encountered in example 1, although this time by negotiating a set of harmonic changes. Specifically, this progression is a IV7-II7-V7-I7 sequence in D (G7-E7A7-D7) and much of the single-note vocabulary is drawn from these chord tones with appropriate extensions, such as the #11 on G7 (C#) and both flattened and raised 9ths on E7 (F F#, enharmonically equal to the much more readable G natural). Again, give the suggested fingering and articulation directions a whirl before exploring your own alternative options.
