The glasschord (French: fortepiano à cordes de verre) is a struck crystallophone resembling the celesta.

[1] The glasschord was invented circa 1785[2] by physicist[3] M. Beyer of Paris.

[4][5] It creates sound by using cloth covered wooden hammers to strike glass tubes laid on a cloth strip, with no dampeners.

[1] The instrument was largely inspired by the glass harmonica created by Benjamin Franklin,[6] and was given the name glasschord by him.

[7] On 6 July 1785, Thomas Jefferson that Franklin carried a version of the instrument with him, describing it as a sticcado.
