“Flop Eared Mule” is a popular old-time and bluegrass acoustic jam session tune. Some fiddlers call it the “Blue Bell Polka.” The form of this tune is called a “cotillion,” which means you always end the tune with the “A” part. There is an interesting key change in this tune, from the key of D Major to the Key of A Major in the “B” part.
Jeanne Page offers below two arrangements of “Flop Eared Mule” from her Mel Bay book Bluegrass on Hammered Dulcimer. The first is basic version, and the second is more like a fiddle would play.
