Does anyone have insight if the traditional exposed metal part of a harp (tuning pins, nuts, pedals, discs, etc.) can be made with a carbon based material?
I did notice that the tuning pins on the violins, violas, and cellos are made of a carbon based material.
There is an interesting story at the Luis and Clark website (under Natural Disasters) that explains the success story of a cello surviving two weeks under water after Hurricane Katrina.
I also have noticed that the instrument insurance policies exclude intruments within a certain distance from the ocean. I’ve heard horror stories how the metal parts of a piano along the coast have been destroyed within a year. I’m sure the harp would be the same.
