My guess/experience is that it's a tunability issue. I don't experience problems in tunability where the difference represents such a small percentage of overall string length such as are found in the bass sections of many pianos. The same thing can't be said in the case of the Steinway "ringing bridge" where the speaking differences in the capo section represent a higher percentage of speaking length. That being said, when redoing a piano/bridge, I would equalize the lengths.

I have notched the new bass bridge in the bicord area. However, the pinned-cast-iron upper termination is in a horizontal line, whereas the strings are at a fair angle - hence, the left string of each bicord is a few millimeters longer than the right string. I should think it fair to assume then that redoing this upper termination to produce equal string lengths would be of some benefit. > > My question is: would the benefit/difference be audible - would it make for a better piano to the discriminating ear? > > I should think the difference would be much the same as on a grand that has agraffes in the bass and the bicord area of the bass bridge is at a fair angle to the strings and is upgraded from a continuous single bevel to proper notching. Does this upgrade on the small grand result in an audible improvement? > > Terry Farrell > _______________________________________________ > pianotech list info: https://www.moypiano.com/resources/#archives
