Buckin Dun

Tobias Enevoldsen (fiddle) and Anders Færgeman (banjo) at 10:40pm. They have versions with five and four players.

A simple square tune in two equal parts. Key of A and fiddle might as well cross-tune (AEAE). Buckin Dun is also called Bobtailed Mule, but so are other old time tunes.

Dun?

It is fun to say Buckin Dun at a jam.
A bucking dun is a grey-brown mule who bucks.
Bucking Mule is a completely different two-part old time fiddle tune in key of A.
