Hi,
What did Tomo play Lesson 43 7:55 to 8:00?
It was a descending run. It sounded like it might have come from a the diminished run inside of a B#7 (b9), or maybe related to a GMaj7 arpeggio...I couldn't identify it...And then the run seemed to change into an E chord sound (?).
Tomo is playing over the chord changes. The chord, at 7:55, is B-7, moving to E-7 at 7:59. So, just listen, and you've got this!
Tomo would like to add this: "The scale is E Harmonic Minor, which has a B Mixolydian (b9) (b13) sound."
