Glad to hear Gordy Hinners mentioned -- he's great -- met him when the Ramblers were running a string band class at Augusta Heritage Workshops in West Virginia in the early 90s.

Far as I can tell, Arkie, there's no consistent, clear definitions that distinguish between clawhammer, rapping and frailing - I've read definitive statements from various sources that contradict each other. Best not to get too serious about the banjo. The operative word relating to the instrument is "play."
