I was thinking of those little niggly things which don't quite add up, no matter how much thought is given to it. That one question on one little point, rather than a discussion of the whole subject.
It could also be a place to talk about one's own light-bulb moment/moments when something suddenly became astoundingly clear. Too late to change the thread title though.
One of my bulb moments was when I realized that chords were generally made up from the odd-numbered notes in a scale. A batch of such tales of revelation in one place might be helpful to some, I thought.
Regarding the example I gave of my own frustration in the past, I've never seen anything in a web music forum which directly asks: Why does a piece of music sometimes contain notes not in the key scale?
Perhaps there are people studying theory who haven't got to the point where they're aware that this happens. Perhaps some lack the confidence to enter into a full-scale forum discussion on what seems quite advanced stuff.
You are right in what you wrote, but maybe questions/revelations will come in and spark something interesting and helpful.
