What scale does he base his first arpeggio on? He uses what seems to me an augmented C chord here as well as at 22:41. How does this relate to the D minor pentatonic bass line? Is thie arpeggio based on the whole tone scale? But he also has a B as the first note - pickup note-of the improvisation - this is not part of the C whole tone scale. Much of his solo seems based on d minor pentatonic licks, but then he breaks out in these spots to get out of that key. What scale does he get those "out" notes from? I hope I am asking a legitimate question here.
I am referring to the duet he does with Jerry Jermott that starts around 21 minutes into the video.
theres a c maj 7 arpeggio he plays if we're looking at the same spot. theyre not "out" notes.
