Bowed zither

"Heartshaped Petzmayer model. Asymmetrical heart-shaped body of rosewood, with two tear drop shaped soundholes. The three wire strings are tuned at a projecting head at the wide-end of the body, by enclosed worm-gear machines and ivory tuning pegs. The strings are sounded at the narrow end, with a bow which is now missing". Baines, Anthony. Catalogue of Musical Instruments in the Victoria and Albert Museum - Part II: Non-keyboard instruments . London, 1998, p. 71.
