Rocks and stones are frequently used by the musical industry, in names of genres, bands, and lyrics. The Jamky instrument – designed by Ján Šicko, Roman Mackovič and Jonatán Pastirčák – uses them literally. The wooden grid comprises of several holes with sensors connected to the loudspeaker. Its sound and rhythms are set by the location of stones in the holes.
The Electronic Beats website writes that it can be used also as a tool for children to learn musical processes.
