Good stuff, Will! Very straightforward and understandable demonstration of what's going on.

The early part, such as "thumb-fingers, thumb-fingers" is what I refer to (or have heard referred to) as "Burl Ives Basic." In fact, he did little else. Then you have some arpeggio patterns and what Pete Seeger referred to as the "lullabye lick."

Then, in "7 – Basic Fingerpicking," is what I was taught as a basic pattern for learning "alternating bass plus melody," followed by "8 – Basic Clawhammer" and on into—yup—Freight Train.

Anybody who wants to learn this should bookmark your demo! I wish I'd had an intro like this when I first started to learn it. Excellent!

What I was whining about above is that some people use "fingerpicking" to refer to anything done with the fingers and thumb, while others reserve the term for "clawhammer" and beyond. Get's confoosin'!

P. S. I'm going to have to investigate the rest of the stuff you've put on YouTube!
