Wave dispersion in stringed instruments: What makes tuning a piano so hard?

Ideal strings have wave speeds that are identical for all frequencies.  In real life, strings have some stiffness that makes higher frequency waves are faster.  This means building and tuning some stringed instruments, like pianos, is very tricky. This project aims to accurately measure wave speeds on piano strings.
