Edinburgh collection checklist
Folder 39, image 177
An annotated page of A Check-list of the Percussion Instruments in the Edinburgh University Collection of Historic Musical Instruments by James Blades, published in 1982. Baines has drawn a glass bar and the hammer mechanism of the jeu de timbres, a keyboard instrument rather like the celeste, but where the hammer strikes a glass bar rather than a metal one.
The instrument, also known as a fortepiano à cordes de verre, or glasschord, was invented by Beyer of Paris around 1785. The Bate Collection holds a glasschord made by Chappell & Co. (no. 896).
