How We Hear

[Don]

Hi,

I believe in as clean as possible unisons. Ideally no partials should be
beating. If it were not for the coupled motion of strings that would be
impossible, instead of difficult. Humidity change takes care of them being
not pure fast enough where I live.

If as I said, I "tune" a 7th partial, using an etd, then the unison is
*not* clean, or rarely is. I have not taken the time to investigate which
partial the "noise" was in, nor tried to measure "widths".
