Muting high treble

[Jay Mercier]

I have found that my muting felt does not add enough tension to the strings 
to PHYSICALLY change the pitch, but will indeed change the pitch a tad sharp 
when muting trichord unisons.  I know there's an explanation for this but 
let someone else explain.  Many pianos don't allow my muting strip to make a 
difference - there's too much bleedthrough.  That's when I use the black 
rubber.  Someday it will be nice not to have to use any muting strips.
