[CAUT] [pianotech] ETD stretch vs pure (octaves)

[Paul T Williams]

Then again, some visiting artist like a big stretch.  I'm tuning now for 
Pablo Ziegler.  We'll see what he likes. 

Any of you tuned for him???  He seems like a nice man, but haven't 
discussed the tuning for tonight yet.  Off I go..

For the most part, the smaller the piano, the more I stretch.  All you all 
in that sort of mind set?  there comes a point where too much of a good 
thing hurts the whole project!  I still stretch the Steinway D a tiny bit, 
more it sounds better to keep it a bit more pure.. My stretches are not 
very huge in the D, but my ear tells me to still stretch the octaves a bit 
around the killer octave on up, but again...not too much. 

just my 3cent stretch to c-8

Hi Duane...

As long as I'm checked in for the moment.

I'd have to answer your question by saying everyone stretches octaves 
one way or the other... Its just a question of how much. We can not 
escape from the fact that an <<octave>> in the piano is comprised of a 
whole slew of 2:1 relation overtones.  2:1, 4:2, 6:3, 8:4 etc.  These 
mesh together one way or the other no matter what your gut feeling sense 
of what is right or not tells you.  "Stretch" per definition is really 
nothing more then what balance of these, or what accent your place on 
one or more of the coincident orders.  You could, I suppose call it 
"Squeeze" instead as it amounts to the same in reverse.

A well tuned piano is nothing more then how well the tuner 
executed/achieved his/her conscious tuning objectives... which more or 
less precepts the tuner is conscious to begin with.  An ETD is so in the 
sense that the pre-programmed parameters reflect the programmers 
conscious tuning decisions.  To some degree the ETD user can influence 
this by what tweaks he/she imposes on the ETD.  And in the end an aural 
final pass can be significantly reflected in the end tuning if the tuner 
knows intellectually exactly what he/she is after and how to go about 
achieving it.
