That is very true, Fran. If I get a request for a song I don't often do, I may do it in C, or G, but it usually follows normal progressions.

I was told by a great musician years ago, that you have to learn to trust your ear. When you do, you can throw away your crutch. Of course, it helps to have at least a little theory, or know the circle of fifths.at least.
