Glass harmonica Franklin and a fellow of the Royal Society, extended the experiments of Pockrich, contriving a set of glasses better tuned and easier to play. During the same decade, Christoph Willibald Gluck also attracted attention playing a similar instrument in England. Benjamin Franklin invented a radically new arrangement of the glasses in 1761 after seeing water-filled wine glasses played by Edmund Delaval at Cambridge in England in May 1761. Franklin worked with London glassblower Charles James to build one, and it had its world premiere in early 1762, played by Marianne Davies. Writing to his friend Giambatista Beccaria in Turin, Italy,
Glass harmonica years of experimentation, Finkenbeiner's imitative prototype consisted of clear glasses and glasses later equipped with gold bands mimicking late 18th-century designs. The historical instruments with gold bands indicated the equivalent of the black keys on the piano, simplifying the multi-hued painted bowl rims with white accidentals as specified by Franklin. Finkenbeiner Inc., of Waltham, Massachusetts, continues to produce versions of these instruments commercially , featuring glass elements made of scientific formulated fused-silica quartz. French instrument makers and artists Bernard and François Baschet invented a modern variation of the Chladni Euphone in 1952, the "crystal organ" or Cristal di Baschet, which
