Luthiers who build Hurdy-Gurdys (as spelled in Wordweb) go to considerable trouble to MAKE them buzz, in several fashions. Otherwise they sound like Cellos with the wrong rosin on the bow. And within the buzz, a player can set up a rhythmic element with fine handle control.
A friend of mine built one. A piece of woodworking artistry, even undecorated.
I seem to remember reading that Samuel Pepys complained, after a musical evening, that "The Hurdy-Gurdy could not be fixed in tune."

A mild buzz never hurt anyone, unless they were driving home. Twangs, though, can drive you mad. Plucks come from inside a pig, and are made into sausages. And faggots. Bows are what little girls wear, and there are too many fiddles in the world.

I think I'll stop now.
