Learsfool, I don't want you to leave this thread, but if you and Frogman make an absurd statement in unison, the fact that you both are accomplished musicians, will make it no less absurd.
You can not practice "improvisation"; how can you answer a question that has not even been asked? And you are saying that you can practice answering questions that have not been asked. If that's not absurd, I would like to know what is. "Improvisation" is spontaneously playing music, the right music, that fits in after the soloist before you. Now explain to me, how you can practice that?
You go on to state,
"Honestly, O-10, any good student musician, and certainly all professionals, can do what you are talking about here, no matter what type of music they play. Your last sentence above is truly absurd for this reason."
That statement was too "wack" for words. You are saying any student musician can do what Oscar Peterson, Sonny Rollins, and J. J. Johnson wished they could do; they wished they could transfer their thoughts to their musical instrument.
That last paragraph is almost comical: You are bothered by my "anti- intellectualism", and Frogman is bothered by my arrogance. As they used to say in USAF, My heart pumps purple panther piss for the both of you.
Enjoy the music.
