I knew R Lee Ermey.. the man was very kind. I get the army drill sergeant being this way. He is preparing men for war.
But music coaches or sports or anything else.... I cannot fathom being talked to like this.
fwiw,
The sad reality is people see movies like this and think that these people exist. They even think it's common.
I am sure the acting was amazing. But, I have no desire to watch this kind of movie for entertainment. I don't watch horror films either though.
No, read the Peter Erskine link I sent. He said "
they wouldn't last beyond their first class/lesson they had... " I mean, even back then. Watch the movie, and see what happens to "that guy". BTW sports, is war, if you don't mind me saying, your competing
against a protagonist/enemy anyway. And if you think "hey, it's not violent" well then, look at all MMA, boxing, karate, judo yada yada... it's instead of words...
I do think very well such people has existed in one form or another way back. In music education too. Note I say this in past tense. When I saw these scenes in the movie, I just giggled, and I would do that in real life too. I giggle and would be amused by the poor fellow turning out a laughing stock, instead of "ruling by fear". Sad git. His demeanor is counter productive. And if someone would've laughed at him, he would just got worse, and the laughter would grow. BTW I agree with the Peter Erskine interview, that the instructor himself wouldn't be able to find the right tempo himself with just two beats count in. You must have four. He flubs the countdown himself. If I was the dean, or his superior I would yell that into his ear too, see if he can taste his own medicine. He would have turned deaf on that ear perhaps, but such people shouldn't do music anyway....

J.K. Simmons himself did have a music background if I can remember properly. His father was a music teacher

. Maybe he took inspiration from his old man...?

This with count ins, a symphonic orchestra conductor waves his baton ONE beat ahead, no tempo, no four count in. A 4th note ahead. Suck on that for a while.
He got an Oscar for it, and this is that you have to portray, and play so convincingly, that the audience should feel a certain "unpleasantness" within them, although all is a well executed pretend. You should feel that this is real. Played villains, nasty people gets Oscars all of the time. Otherwise you'll lose all the drama.
Now, we're derailing the thread. I was only suggesting to OP that if you blow your top, it is sooner or later coming back and bite you in the butt. If the OP thought that playing that gig will put him in bad light afterwards for it being a really bad gig, and no one would hire him again afterwards, it's nothing compared to what this demeanor and manner will do. This would hurt him more.
Rightly so, he reached out here, and did have doubts on this matter, and it seems solved by now. He did sense a "maybe I went too far..." feeling anyway, and that's what counts in the first place. This sense of him doubting his own manners should not be underrated. You make amends, apologize, and do not hold grudges, and moves on.
Remember, Charlie Parker got thrown a cymbal at him, on stage, live, in front of an audience.
