The definition of lithophone is "any of a class of percussion instruments (such as the qing) that are made of stone and whose sound is produced by striking" Pretty dry and dull when you see it in print. However, if you have audio capabilities on your computer, I recommend you crank it up and cut-n-paste the link below (I added a space between the first and second W in the "www", just in case there was something commercial about this video) This young lady "rocks".
Anyone gonna make one of these?
