[CAUT] More on Single String Beats

[Otto Keyes]

Had one of the 5' 7" Sohmer grands.  Styling was very nice -- one of the
prettiest grands of its size I've ever seen.  It could be voiced to
sound pretty good, but anything over forte got pretty
wrangy....downright nasty at fff.... and there didn't seem to be much
you could do about it.  Nice idea, but there's usually a reason why they
don't make certain stuff anymore. (eg:  squares)

By the way, Thanks to those who responded to my last post.  I appreciate
the encouragement.  I will get back to you all at some point!
