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 i<SPAN class=400250821-14062003>n</SPAN> 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.</SPAN></DIV> <DIV><SPAN class=390222716-13062003>   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.
