There's a part in D-Natural Blues (Wes) that no matter how "I" play it, it sounds wrong, but when Wes plays it, it sounds perfect.It’s funny when you slow it down and try to learn it, cause you have to gauge what’s a mistake and what’s intentional.
On giant steps at one point coltrane rams a D natural over the Bmaj sequence in anticipation of the Gmaj section, and it seems pretty intentional, but there are other points where he hits the maj 7th on the Bb7 and I think it’s just a mistake. In the latter case for your own sake I think you have to decide that it’s better to play the changes and not the actual solo.
Similarly Wes does some things like that as well, but then other times he’ll sub a min7 or min9 arp over dim or half dim, but it sounds cool and he’s doing it on purpose (maybe for facility’s sake?), so just roll with it and do it his way.
