..................They also compress
the outer surface of such components by shot peening them (bombarding them
with steel shot)but this does not look like a feasible strategy for
harmonica reeds.

Bead-blasting, the same peening process but with very small glass beads,
might be feasible on reeds. Tuning to lower pitch would spoil the effect,
if any. Do you think that peening might alter pitch?
