Example BLUES SOLO 6 ...CONTINUED
The notes in the country-influenced line in this bar are taken from E Mixolydian, and most of them are E7 chord tones. The first seven notes in this bar are all notes of a D major triad, thus outlining the underlying chord. Even though the remaining notes are a return to an earlier musical motif, note how only one note isn’t a chord tone of D7. Finally, the bulk of this section is devoted to the A7. Again, most of the notes are chord tones: even the C notes are trying to inch their way back to the more ‘correct’ C# notes ‚ occupying that harmonic no man’s land that gives the blues some of its grit. Customarily, although there are many chord tones to choose from over the E7, the root is the only one played here; conveniently, it also belongs to each of the various prevailing A scales used throughout the solo (Mixolydian, major Blues scale, minor blues etc).
