Need help.</DIV> <DIV> </DIV> <DIV>Steinway D model, about 18 years old. This piano has always had a problem in the treble from about F5 to B6.  Tone is hard and sustain is short.</DIV> <DIV> </DIV> <DIV>Over the years I have tried voicing the hammers and can balance the tone, but, to the expense of the sustain, this drops of even more.</DIV> <DIV> </DIV> <DIV>Today I had a note left by the visiting European pianist,  Michael Leuschner (prior to my visit) asking that I voice the treble, especially between B & B. "The sound is hard and doesn't last long enough" B6 isn't bad.</DIV> <DIV> </DIV> <DIV>I needled the surface area to even out the tone through this area and the pianist was happy with the result (needs this area as he is playing Mozart & Chopin) but, I really want to fix this problem and because I now have a note from the 'teacher' I have an excuse to fix it.</DIV> <DIV> </DIV> <DIV>What is the problem ?  I have my thoughts but I only work on 1 Steinway, some one must know what is causing this to happen.</DIV> <DIV> </DIV> <DIV>Regards</DIV> <DIV> </DIV> <DIV>Tony Caught ICPTG<BR>Australia<BR><A href="mailto:caute@optusnet.com.au">caute@optusnet.com.au</A></DIV> <DIV> </DIV> <DIV> </DIV><FONT size=2 Arial></BLOCKQUOTE></FONT></BODY></HTML>
