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 align=baseline border=0 height=117 id=_x0000_i1025 src="cid:890033722@14062003-1c2a" style="HEIGHT: 36px; WIDTH: = 231px" width=583><o:p></o:p></DIV> <DIV id=hotbar_promo> <HR align=left color=gray noShade SIZE=1 width="100%"> <A = href="http://promos.hotbar.com/promos/promodll.dll?RunPromo&El=ho= tbar%5felement%3bst%3b&SG=&RAND=99399"><IMG alt="Upgrade Your Email - Click here!" border=0 = src='http://promos.hotbar.com/promos/promodll.dll?GetPromo&El=hot= bar%5felement%3bst%3b&SG=&RAND=99399"' title=""></A> </DIV></DIV> --- Incoming mail is certified Virus = Free.
