A verrophone ("glass-euphonium") is a musical instrument, invented in 1983 by Sascha Reckert,[1] which, "uses tuned glass tubes,"[2] open at one end and arranged in various sizes (usually in a chromatic scale, arranged from large to small, like the pipes of a pipe organ).
Every piece composed originally for glass harmonica can be played on the verrophone.
The verrophone is capable of louder dynamics than the glass harp due to its larger radiating surfaces.
An example can be heard in a work entitled "Crystal Bones" composed and played on Prophet's microtonally tuned glass instruments.
