John:
 
Would it be sensible to make a distinction between "tuning" touch, and  
"stabilizing" or "test" blows or touch? When I'm tuning, I use a  relatively 
light or medium touch to hear what I want, then give the key a harder  
(stabilizing) blow with a bit of sustain. I may do that twice or three times on  
each note. If the note stays where I want it to, or if it actually drops down  
that whisker of frequency i want in order to create the interval  or 
unison, then I'm doubly gratified. The quiet touch tuning works especially  well 
in the treble, as does setting the string with a short series of  stabilizing 
blows.

You can  try what someone from Steinway (John Patton perhaps?) taught.
Use a hammer  shank to see if the string is set. Apply lightish
pressure on the string at  about the same angle as the bridge pin.
You'll probably have to experiment  with how much pressure is needed.

If stable, the pitch won't  change.  However, this is cumbersome. I
tried this for quite a number  of tunings, and have since gone back to
a firm test blow merely for the  sake of speed.

My firm blow is usually no harder than the weight of my  hand and arm
falling on the key. One or two of those blows will prove  stability.  I
need to get into the habit of letting my arm fall on the  key to save
my joints. Hard to break old habits.
