comment Why is the highest frequency on a piano 4186 Hertz?
Well, I took a swing at a scientific answer below. I completely agree that instruments evolved by trial and error and not with physics. However, the laws of physics were their first and are the foundation of the "trial & error" even if the builders weren't aware of them. Now that we know these laws, we can understand this a lot better cut a out a few hundred years out of the process :-)

comment Why is the highest frequency on a piano 4186 Hertz?
Being a scientist and a musician, I completely disagree with this statement. Most things that happen in musical instruments are very well grounded (albeit mostly empirically) in scientific laws and principles and theoretical physics and math are very relevant. I'm not trying to be controversial, but this would be a fun discussion to have!!

comment What is the best software, to cut a loop out of a song, for rehearsal purposes?
I find it difficult to set loops in audacity so that you have, for example, exactly 8 bars, so that that I don't loose time at the wrap around point. Is there a trick or plugin to do help do this?

comment Spectrum of brass tones of same fingering
@Gauthier: I reference "G" as the root note in my example, not "C". "E" is not a (lower) harmonic of "G". Or maybe I mistyped and someone fixed it already.

comment Spectrum of brass tones of same fingering
@Gauthier: Technically speaking the notes are determined by the mechanical modes. For a string the modes follow nicely a harmonic series. For a tube that's open on one side and closed on the other, the modes have different frequencies (odd harmonics only). The mouthpiece and the bell are used to make make the tube non-cylindrical and so to dial in the modes to match the desired frequencies. The main difference to a string is termination: The string is equally fixed at both ends, the tube is open on one side and closed on the other.

comment Piano tuning just under the absolute pitch
@Gauthier: I wasn't implying that the clock drift itself is out of spec, but that at some point Apple switched vendors or parts with a slightly different nominal frequency (say for the CPU clock). They have no reason not to.
