"Pago" is Greek for ice, and "phone" is Greek for "sound", so "pagophone" means "ice sound", in much the same way that "xylophone" means "wood sound" ("xylo" is Greek for "wood").

The pagophone is an instrument invented by Steve Mann, and intended to add a unique musical texture to a hydraulophone performance.

These pictures are self-portraits, before and after a pagophone performance by Steve Mann, the inventor, pictured here, playing the pagophone.
