[pianotech] Finger Cymbal Sounds

[Steven Hopp]

David,

 

My voicing experience is minimal at best.  I have practiced reshaping hammers for RPT test and have done hammer sanding with great care and caution on my own piano and a few others.  I have done some needling according to andre' and some others sources.  All very carefully and with what my musical ear says have been good results.

 

This piano got a light sanding of all hammers and the results are good.  The tone is generally even and with some needle work should be good for the age of the hammers.

 

What happened is where I am confused.  The three aformentioned notes are ringing as if there are some very high partials sounding??  Now mind you it is not as if you can not here the fundamental anymore it is just some extraneous noise that pings rings or whatever.  I did check on the B4 and if I mute the left string the sound is much less to almost gone.  I did not have time until tomorrow to deal with this.  I hope this helps.

 

Any suggestions?

 

And thanks to those who have provided them so far.  I am going to take the consensus before I proceed.

 

Thanks,

 

Steven

Do you mean they are pinging?  Or is there some other extraneous noise?  What kind of voicing experience do you have generally (sorry, I don’t mean this question to be offensive)?

Sorry about the lack of info.  
 
Yamaha C7.  Offending notes:  B4, C5, B6.  Piano is 30 years old and has original hammers.  Hope that helps.
 
I am going to check the string mating and my filing.  
 
Thanks again,
