Trichords tuning

[Roger Jolly]

Hi Richard,
                 Yes it will, IF the unicorda position of the hammer is
correctly voiced, and the strings are not striking back into the grooves.
When doing a refined voicing job a lot more time is spent on the centre
string, this I think is caused by the hammer being denser in this area, due
to the way the hammer is cut. ( Most hammer makers slice from molding to
strike point, therefore releasing a lot of tension from the outer shoulder
of the hammer.)  Advanced pianist tend to be quite fussy with unicorda
voicing, particularly when half pedalling.  Centre line needling will even
out quite a bit of the partial spectrum differences from string to string.
Ari Issac a Canadian hammer maker makes his cuts in the opposite direction
to help over come this discrepancy. I have not tried his hammers but it
makes sense to me.
Regards Roger
