So what's the difference if it ends up at the same temperature it started
at?

You don't play it when it's cold, you let it warm up first!!



I've kind of been lurking on this question, but I've been tempted to ask the
same question that Digby asked. What >is< the difference if the instrument
ends up at the same temp it started at? It seems (obviously) that the very
structure of the instrument would have to change permanently if the
performance is to be changed by simply dipping it in liquid hydrogen.

By no means am I saying that this >doesn't< happen; it's just not something
that I'd expect.

It's the mechanical properties of the material the instrument is made of
which change, hence its resonances, etc. Makes a change in the sound
spectrum not the pitch of the notes unless the physical dimensions of the
instrument change. The sound of these instruments is somewhat more than
just a vibrating air column.
