Dissertation on Stalactites
What do stalactites sound like when you hit them with a mallet? Physical simulation, cave field recordings, and a playable virtual instrument
I wrote my dissertation on “Ancient Rock Music: the sound stalactites” make when hit by a rubber mallet. The project was inspired by a visit to Luray Caverns, Virginia, home of the “Great Stalacpipe Organ”: an instrument that plays the cave itself.
The work had three parts: a physical simulation of struck stalactites using finite-difference and modal methods (approximating them as cantilever bars of variable diameter, in Matlab), a field trip to record real stalactites, and a virtual instrument built in C++ with JUCE so anyone can play a cave from their Digital Audio Workstation.
