Most notations are used to mean a dozen different things, so you can't even be sure, if you read about it, you are reading about the right one, if you do find it. And if you find the right one, it still won't say how to pronounce it, so you can't even ask without sounding like a dummy.

It is all very insular. Or, maybe, was, before Youtube.
