I'm not familiar with the numbering system that FM talked about in class last night. How would i find out more about it, on line, for instance? What would I "google"?

If it has anything to do with math, I'm in trouble!

I just searched the forum here, and found the answer: Nashville numbering system....Hope I can figure it out.....Is it as complicated as it sounds?

Not really. Say you're playing in the key of G. Take the G scale. There's 8 notes in it, right? So number each note in the scale 1-8; so in the G scale 1=G, 2=A, 3=B, 4=C, 5=D, and so on. It's easier to change keys if you're using numbers, cuz if you're playing G, C, D (1,4,5) in the key of G, then to switch to, say, the key of C, you would just have to think, "What is 1, 4, 5 in the C scale?"
I seriously need to work on this. I'm not good at making myself stop to figure out what the numbers are. But, 'practice makes perfect.' (or so they say)

See this website for an article on the Nashville Numbering System.

Go to Classroom

see Music theory

That was dificult to understand.....especially the minor and diminished things. Gonna keep trying, though....Wish me luck!

Not sure what you mean by diminished and minor in your post. In the classroom section of the website, I have an article entitled "Fretmentor Lesson - Nashville Numbering System" It is the Music Theory section of the Classroom. Go to the following section of the website. It can't get simpler than this (with a song example to boot):
