Harmonic Highlights
- Dominant 7th chords are extensively used for primary functions (C7 as I, G7 as V), defining the blues tonality despite the C major key center.
- The D7 chord functions as a secondary dominant (V7/V), creating tension and leading directly to the G7 (V7) chord.
- The consistent use of dominant qualities for the tonic (C7) necessitates a blues-centric approach to chord-scale application.
Improvisation Focus C Blues Scale.
Difficulty Rating 3 (Intermediate). The core progression is foundational, but effective improvisation requires navigating dominant 7th chord tones and incorporating blues vocabulary over both primary and secondary dominants.
