(my original question) I am well-educated. I'm new to, and trying to learn, music theory, but the constant hedging on what things mean is frustrating. Can you say ANYTHING that is 100% reliable about any of these musical terms? For example, in science, if you have an atom, then you have at least one proton, and that's certain; in math, if you have 2 plus 3, then you have 5, and that's certain. In music re scale, key, chord, tonal, note, etc, is there anything on which I can rely, from which I can use to reason or predict another reliable fact or definition?

Hello, and welcome to Musical Practice & Performance. This site uses a structured approach to asking and answering questions, which you can read about in help center. This space is used for answers to the question at the top of the page, so this post will be deleted. New questions can be asked using the button at the top right. I will let you know that a question like what you've written here would probably be closed as "too broad" -- my suggestion would be to start at some of the excellent wikipedia articles about Music Theory and then ask here where you need clarification. – NReilingh♦ 11 hours ago
(my reply) I've already been to Wikipedia. The info there, or more specifically, its self-admittedly confusing nature, is what prompted my google search, which brought me to this web page, which, having provided further similar confusion, prompted my question, which remains unanswered. The dismissive non-response I did get only adds to the confusion. My question really is straightforward and easily answerable. Really, it is. Just answer yes or no, and if yes, then please give an example or two. In fact I, gave two examples, from different subjects, of how you might answer it.
