Re: Calculating harmonics of a vibrating guitar string

One thing that I wonder about: do the relative phases of the different
harmonics matter in terms of what you hear?

Wouldn't the presence and/or amplitude of various partials
also vary with the timbre of the "instrument"? Some strings will
be more sinusoid in timbre, some more triangular or square,
based on design, composition etc.

Then there's the exciter. If you excite the string with a
brass pick vs a human fingernail vs a human thumb flesh
vs a felt plectrum, wouldn't you vary the amount of amplitude
for all of the partials? And I don't think it would be even.
ie sometimes the 3rd partial might have a higher amplitude
when excited by a pre-war brass .018 plectrum and the 5th
partial might be hyper-excited by a late 50s .250 coconut shell plectrum.

Then there's the fulcrums. What's at each end of the string?
Brass? Nickel? Iron? Bone? Titanium? Wood? Micarta? Do one
or both of those fulcrums have some inherent resonant points
due to density or lack of?

Get that beginner guy back here. This stuff will make him
a guitarist in no time.
