Deep or wide? (No double entendres HERE, eh? where's Cletus when you need him)
for myself, deep in some areas, wide and shallow in others. I've tried to dig in pretty deep and learn how to sound like Charlie Poole (or like AP Carter, which means I have to do that with two women. . .but that's another story) deep for brother duets (Louvin Bros, Blue Sky Boys, Delmores, Monroes, etc) and the more I learn the more I want to learn.
Wide because there's some areas I just dont know all that well and only think of a song in that area when I hear somebody sing something else RELATED.
Got my first guitar in 1959, banjo six months later, and it's been all downhill ever since.
I think it was Freeman Dyson who gave a very simple geometric analogy on why you never run out of things to learn. Consider a circle-- that represents the things you know-- and the circumference of the circle is the boundary between what you know and what you don't. . . as the circle gets bigger so does its circumference. . . works for me! nt PETE
