why you are tuning this instrument @ 390cps? For that time, in Paris, (which
was the mecca for Erard), most pitches were in the 400cps to 443cps range? I
would have chosen 425cps as a pitch that would put the instrument close to it's
designed pitch/tone and yet not overstress the structure too much. What you are
hearing @ 390cps is NOT the true sound of the instrument, IMO.</span></font></b></strong><font
