This is going to be a quick post as I have to go teach this afternoon and then rehearse with the IU Southeast Orchestra tonight. But I had come across what’s called a “pogo cello” just a bit ago. The wikipedia entry for the instrument states:
The pogo cello was created in the 1950s in Brooklyn, New York by a chemist, Mack Perry, the husband of a music educator, Sylvia Perry. Perry patterned it after a similar instrument called a bumbass (boombas, boomba, or boom bass) also known as a stump fiddle (or stumpf fiddle). Pogocellos were manufactured in Brooklyn and Far Rockaway, New York and in New Jersey. The pogocello was sold in the United States for decades as a musical instrument for children, but many adults also bought them for themselves.
Pogocellos have been seen in marching bands in Iowa and in the Mummers’ parade in Philadelphia, PA on New Year’s Day. Similar instruments may be found today in Australia, Czechoslovakia and in Sweden (a Devil’s fiddle or Devil’s stick) and in other countries, for example at Oktoberfests. They have been played in blues, soul, bluegrass and other kinds of musical groups. Television show host, Garry Moore, played one on his show in the 1950s. Since 1975 the Gloucester Hornpipe and Clog Society, an American traditional music group which plays Celtic, French Canadian, Appalachian, nautical, and other kinds of folk music, has featured a pogocello made by woodcarver Rita Dunipace, and pogocello player David “Doc” Rosen.
A great video describing and demonstrating the instrument:
