Harmonic Highlights
- Features an extended cycle of secondary dominants (
Bm7-E7-A7-D7) functioning as V/A, V/D, and V/G, driving momentum towards the tonic’s dominant. - Frequent use of
Dm7/G(G7sus4) as a substitute for G7, adding a temporary suspension and modal flavor before dominant resolution. - Incorporates an altered dominant
G7#5for heightened tension and chromatic color before resolving to the C tonic.
Improvisation Focus Mastery of dominant scales, including Mixolydian and altered dominant options.
Difficulty Rating 4 (Advanced) – The extended dominant chains and recurring suspended dominants demand sophisticated harmonic understanding and agile navigation.
