She did "Liebestraum" by Frans Liszt - = and did it well. BUT the poor piano - I should say the obscene piano - ZERO = dynamics (and I love Yamahas in many applications). She could play at = high and low volume (I think that has something to do with the action = mechanism.....), but it was 100% loud and less loud. ZERO tonal changes at all. This = was not a piano-forte - but rather as Del might characterize such a piano, it = was a forte! Yuck (for a classical application like this one)!</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Terry Farrell</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; = BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A title=quentin.codevelle@tiscali.fr href="mailto:quentin.codevelle@tiscali.fr">Quentin Codevelle</A> = </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Sunday, May 15, 2005 4:54 = AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Re voicing = hammers</DIV> <DIV><BR></DIV> <DIV><FONT face=Arial size=2>Hello Michael and Andre,</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>A few weeks ago, I learned the exact = formula used by the Yamaha concert techs to harden the hammers when the pianists = want a brighter sound.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Andre, you know this receipe, and I = wonder if it would help in Michael's case.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>It looks like plastic keytop with = acetone mix, but it is not exactly it.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>So Andre, what are the differences = between your method with collodion and the method I speak about?</FONT></DIV> <DIV><FONT face=Arial size=2>the Yamaha method seems to work in = only a few minutes although your method needs one day to get the final result.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial = size=2>Quentin</FONT></DIV></BLOCKQUOTE></BODY></HTML>
