myths

[Dean May]

Anecdotally, my experience is that marginal tuning pins are at their worst
in mid winter. I am aware of someone on this list experimentally proving
that holes shrink in dry wood. These two things seem contradictory.

Perhaps the moisture content does more for gripping the pins than does the
actual interference fit.

Does adding moisture to the block tighten or loosen the tuning pins?  Now
there's grist for the mill.

"Water should be kept in a jar in the bottom of the piano"

Actually, I have recommended just that on two or three instances when people
were in difficult financial straits, and I had some marginal (at least)
tightening of tuning pins over a space of about two months.  They were, of
course, bad pianos and the folks couldn't afford the good humidity control.
