Re: over-all tuning discussions, was How we hearokay, I want to watch the
movement of the rubber mute. How do you tune the whole piano using one
rubber mute? From start to finish, please please.

    David Anderson -
    Apologies if my original question sounded at all terse; didn't think
about it until I saw it in reply-mode. Please bear with me if you've already
covered this, as I'm sure I've probably missed some bits of this
conversation in places until recently. When you say "15 seconds" - could you
go into more detail? IE, are you listening for 15 seconds to the unison each
time you're moving the pin until it's in place, or is the 15 seconds the
final "test" listen?


  Hey Ilex---I certainly don’t listen to every single 2 or 3-note unison for
15 seconds----I should have been clearer: When the unisons are what I call
“coupled,” the note picks up the “bloom” of the soundboard and actually
sounds or feels like it swells, and there is absolutely no phasing or
movement of any kind until the note dies. It is a priori that the strings
must be seated and lifted properly, and that the speaking length
terminations are solid. Yes, you can hear most of what you need to, most of
the time, within 5-7 seconds.
  In actual practice---as with everything else---you get so quick and so
good at moving the pin in teeny increments, and then have it rock-solid
where you put it, with whatever settling blow you’ve given it---that you
move a little quicker, but in a good rhythm. I’m tuning as I go, with just
one rubber mute, so everything is pretty clean and precise.

  I take what most people would think is a horrifically long time---about 30
minutes---to really ideally, precisely, and firmly set the temperament,
with all 3 strings per note tuned. It takes me from 50-60 minutes to tune
the rest of the piano. Many, many tunings have I done for monster players,
who WILL move the note if it can move, so I’m pretty confident of ability to
produce a stable tuning.

  But I’m old, and kind of eccentric, and diminished by years of what one
friend has politely called “rugged living,” so I belong out in this old
school pasture of has-been Jurassic geezers.
  (The above is irony; not intended for less than mature audiences.) <G>

  Hope this helps....

  David Andersen
