5th and sixth octaves, huh? Killer octave, huh? Now you've got me curious
and I've got to try this on a couple of different soundboard designs. You
don't suppose... Impedance, fundamental resonant frequency? It seems to me
that all this almost certainly connects. Del, did you ever notice a
correlation here? Well, anyway, when I get some pianos up to take some
measurements from, I'll take notes and see if I can eventually make sense of
anything.
