12 Bar Blues in D#7 (Jazz Variation)
The Jazz variation of the 12 Bar Blues in D sharp adds some extra chords. The 12 Bar Blues structure remains the same, but certain chords are substituted. For example, the D#7 chord in the fourth bar is substituted with an A#m7 moving to an D#7 chord.

For example, technically in bar 8, there should be a Fxm7 (F double sharp minor 7), followed by a B#7. Although technically correct, these labels are a little bit awkward and impractical, so they have been replaced with their more common equivalents.
