Not only that, but you put in some more jive bs that will blend in with Learsfool's jive bs.
Herbie played a wrong chord, had Miles not previously "practiced" playing over that type of (wrong) chord, that moment would not have been possible. That knowledge became part of his arsenal which he could draw upon in order to be spontaneous.
If that ain't some jive BS I don't know what is; but it matches Learsfool's jive BS about practicing improvisation, which is "impossible"; that's like saying you're going to practice a "tennis match" without anyone on the other side of the net.
You have gone so far with your "diatribes" (that are not supposed to be diatribes to prove me wrong) that it's gotten to be a habit.
Call him out on this "aficionados", and maybe he'll quit.
Enjoy the music.
