Harmonic Highlights:
- The progression adheres to a dominant 7th chord 12-bar blues form (I7-IV7-V7), firmly establishing a blues tonality in F.
- The F7 functions as a tonic dominant throughout the I sections, a hallmark of the blues genre rather than a traditional Imaj7.
- A distinctive chromatic passing dominant occurs with the C7-Db7-C7 movement, where Db7 acts as a half-step approach or a bII7 substitution to the V7 chord, enhancing blues tension.
Improvisation Focus: F Blues scale.
Difficulty Rating: 2/5 - The changes are a standard blues progression with a common chromatic alteration, making it accessible for intermediate improvisers.
