New Orchestral Instrument Held in Rack While Played
A scarcely recognizable, but truly lineal descendant of the humble cigar-box fiddle has made its maiden appearance on the American vaudeville stage. It resembles in shape an overgrown banjo, but is constructed throughout like a violin. Only one string is used. The instrument is not held between the knees like the cigar-box fiddle, nor under the chin like the violin, but is supported at about 35° from the horizontal and four feet from the floor, by an ornate brass rack. Standing beside his instrument, in this position, the inventor-musician plays it with a modified cello bow.
If anyone can dig up more information on the instrument, the inventor and especially the show it appeard, please send it to Shane Speal at shanespeal@yahoo.com
This is so typical of the Gimmick Age (1880 -1925). A one string cello mounted as such is very easy to play. I have been designing and building musical instruments all my life so I have tried this. I will post a new instrument using a cigar box at CB Gitty soon.
I’d like to see that in action!
