Computational Design of Metallophone Contact sounds by Columbia engineering shows how to optimize a customized instrument with computational design and digital fabrication. For each sound spectrum, the computer optimizes the surface with isotropic scaling optimization. I found this project very interesting because computer technology will continue to develop and will produce more accuracy than ever, which means that musical instruments will eventually be more intertwined with computers. But how will technology have more influence on classical instruments than now? Until when will classical instruments remain as the most prestigious instruments?
