I have to say, I'm always amused by these discussions that broadly
outline the imprint of theoretical measurements on the phenomenon of
sound. If we look at all the factors, including thickness and
stiffness of string material, variability in trueness of dimension,
interference of temperature and humidity (and probably barometric
pressure) on the transmission of sound, proximate acoustical
deflections, damping caused by skin oils, distortion caused by finger
pressure, variability caused by thickness of fret material, wave
interference from nut, bridge, soundboard materials, etc. Then there
is the phenomenon that different ears hear the pitch differently. Where
do we stop? I say train your ears and tune to the best of your ability.
