There is an interesting article (I don't think its on sneezy but
its referenced from there) on the fact that the instrument walls are 30db
(that 10000 times) softer than the air column. Therefore, wall vibrations
are negligble, and therefore in terms of sound, material. The main pro to
grenedalia, as I understand it, is its relatively low cooeficent of
thermal expansion, and low specific heat compared to metals.
