I've always wondered about that.  I would presume the slant of the bridge
pins and the severe angle of the string between pins is intended to keep the
string pressed firmly to the top surface of the bridge, but wouldn't the
downbearing already achieve that?

Perhaps the downbearing isn't severe enough on a piano (vs. other stringed
instruments such as a violin) to maintain string/bridge contact during
intense vibration???  Perhaps the additional pressure is needed in the event
that the soundboard flattens and the downbearing becomes too slight???
Perhaps the consequence of not having the slanted pins and high lateral
forces is that the string would sometimes buzz against the bridge surface???

What performance benefit(s) does the current design offer?  What problem(s)
does it prevent?

What would happen if a string were passed straight over the bridge without
pins, like on a violin?  What would happen?  How would it sound?  Has anyone
experimented with this?  (The appendix was once a "good idea," but it's
become obsolete and problematic in our species.  Perhaps bridge pins are
also an obsolete and problematic relic from early in piano history???)

Thanks for any insights!

Peace,
Sarah
