missing photos / individually looped strings, etc.

[Jerry Cohen]

Actually, the individually looped string is less stable when the piano has
recently been strung. This is because the string is still tightening and
forming around the hitch pin. After some time, the stability of the
individual and the shared string method is the same.

Recently I spent 3 weeks at the Bosendorfer factory working on voicing. I
was working with recently strung pianos. The difference in stability between
a standard model (individual loops) and a Conservatory (shared strings) was
dramatic. At that early stage, the lower cost Conservatory was much more
stable, even though it is identical in design except of the shared strings.
After some time and enough tunings, the stability is the same.

Hi Dave,

Yes individually tied strings are less affected by pitch drop when raised
to pitch. My personal theory is that the plate flexes much less with
individual hitch pins.
