Does von Otter have "symmetric" chords. How can we tell if any differences
are due to chordal symmetry? Are there other explanations?

Does all of this presume that we fully understand exactly how a chord
actually generates a soundwave? Is the waveform parallel to the entire
length of the chord with each chord vibrating in perfect synchrony to
generate a pitch. Or are there one (or more) nodes in the vibration
pattern? Or is the wave generated in the apposing surfaces of the chords
(in which case chordal symmetry would seem to be to be of little
significance)? Or is the wave form even perpendicular to the chords and
generated at several contact points between apposing surfaces?

Is there an engineer in the house?

Openly ignorant,
