I hope this email finds you all in = good health.   <o:p></o:p> <div>    I have ran into several pianos that all have the same problem, which I = believe is caused by something that may require major repairs, but I am at a = loss as to what the real problem is. The problem is this. You can play all the keys = to check all the notes, and you'll come to a section of notes that won't = play. The hammer hits the string, but the only sound it makes is, BONK! The = strings do no resonate as they should. You can pluck the strings, and they sound okay. = You can hold the damper off the strings, but when the note is played, the = only sound it makes is, BONK! It sounds almost as if the hammer is hitting = wood, instead of the string. This is only in a section of notes, and in the = case of the U1 I inspected today, it was a little over an octave's worth of = notes in the upper tenor section, just before the treble break. All the bass and = all the treble was okay.<o:p></o:p> </div> <div>    Is this a problem with the bridge somehow? I have seen this problem = where only two or three notes are affected, and another piano where the entire = tenor section was dead, and I have had no solution. I feel bad that I have = studied and been in the practice for so long, but have no solution to this = problem. Can someone help me out? Thank you.<o:p></o:p> </div> <div>  <o:p></o:p= > </div> <div>  <o:p></o:p= > </div> <div>  <o:p></o:p= > </div> <div>  Richard Strang<o:p></o:p> </div> <div>  <o:p></o:p= > </div> <div> <img width=583 height=117 id="_x0000_i1025" = src="cid:image001.gif@01C33290.D464C880" style='height:36px;width:231px' align=baseline = border=0><o:p></o:p> </div> <div id="hotbar_promo"> <o:p> </o:p= > <div class=MsoNormal style='margin-left:.5in'> <hr size=1 width="100%" noshade color=gray align=left> </div> <a href="http://promos.hotbar.com/promos/promodll.dll?RunPromo&El=ho= tbar%5felement%3bst%3b&SG=&RAND=68533"><img border=0 = width=416 height=72 id="_x0000_i1027" src="http://promos.hotbar.com/promos/promodll.dll?GetPromo&El=hot= bar%5felement%3bst%3b&SG=&RAND=68533%22" alt="Upgrade Your Email - Click here!" = title=""></a><o:p></o:p> </div> </div> </body> </html> --- Incoming mail is certified Virus Free.
