two strings flatter than one,

[Richard Brekne]

If you can get a hold of a copy of "5 lectures on the Acoustics of Pianos" given
out by Askenfelt, you will find a really good article describing some of what
this is all about. Also Conklin has done some hardcore research into this matter.
Also this months Journal has a good article that touches on this a bit.
