Perry's musical rendition of Jon's rocks breaking:

This is a 15 minute composition written in the Chuck audio programming language. There are 4 distinct sonic "scenes," beginning with the crackling of the granite breaking (multiple delayed and reverberated loops of this). Slowly, tapping sounds begin to augment, then replace the cracking sounds. These taps were Jon's actual hammering of the shims used to split the rock. This eventually grows into a rhythmic pattern, based on a meter of 17 grouped as 7 + 5 + 5 (there are 17 stones in the lithophone). The crackles return to replace the rhythmic tapping, then the piece concludes with hammering sounds that almost approach those of woodpeckers. These final sounds are isolated strikes of the impact drill Jon uses to make the holes that will eventually be used to split the rocks. All sounds heard in this exhibit are those of the stones and the tools used to break them. Thanks to Jon for letting me "look" into his rocks with my microphones.

About the Electronics:

Each "bar" of the Lithophone (stone xylophone) is affixed with a piezoelectric contact microphone. These transfer the vibrations to a box containing some simple digital signal processing equipment, which adds delays and reverb to the xylophone sounds (simulating a cave-like environment). Enjoy the sounds!!
