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?
