Experiment: string termination / duplex / Calin

[CalinTantareanu]

Hello Joe,

I didn't do any tension calculations, but I would say the tension was high
enough for a brass string. I even managed to break two strings while playing
around with the monochord.
Anyway, the experiments were done at similar tension, so the overall value
shouldn't influence my conclusions too much, I hope.
