I can't believe how easy you made this to comprehend.... Thank you. WOW. Usually the explanations I get on this are so bloated with over complexities and unnecessary exposition that I just say "forget it" and go play video games or cry myself to sleep.
I am very interested too. Yes, that is a good video. The teacher speaks slow enough, so that the student is able to follow. That's especially important for non-English or not-American students like me. Then there is sometimes a problem with spoken English language. How with me. Written English language is not the problem for me.but spoken language. If is spoken too fast, is it rather until hard to follow really. You lost your concentration and get tired. Ten you change to another video and hear some music, or you go to eat a bit or go to loo or do something else, but you do not listen to the video any more. Or - you look for another, better video. Or you try to write a fugue on the basic of them what you have already understood.
