Shnauffer closes his Tennessee Music Box CD with a bowed song. The name of it escapes me; not that it's so forgettable, but I wouldn't want a steady diet of excessive drone. I think Arkie's got it right -- it's a novelty.
Lorraine Hammond has done some bowing and I believe she has worked with Duane Wilder of Bear Mountain Dulcimers on some design elements for bowing. One is the addition of four small semi-discs that function as legs so you can set the dulcimer on a table to bow it.
I sure would like to hear more about Blue Diamond Mine. I think my grandfather worked there before he moved to Pinetop, Ky., from Allock, although his section of Pinetop was known as Spider before they closed the post office.
