Greetings,

 

           I should know this, but I forgot; approxamately (ballpark) how
many tons of tension is on a harp plate when the piano is tuned to A440?
Does this tension increase per size of piano? In other words, is there more
tension on a 9 foot concert grand than a spinet? Also, on grands, do plate
nose blots ever loosen, that a tuner would ever have to tighten them?

 

Thanks in advance,

Julia Gottshall,

Reading, PA
