[pianotech] ETD stretch vs pure (octaves)

[David Love]

For me smaller pianos get less stretch and a narrowing of the octaves.

This has long been a point of confusion for me.  Smaller pianos typically
have higher inharmonicity, requiring more stretch in the octaves in an
attempt to match the higher partials.  And yet on RCT, the higher OTS
(Octave Tuning Styles) are recommended for bigger pianos.  We had Karl
Lieberman out a couple of weeks ago and I think he recommended using OTS 7
or 8 on Steinway D's.  

 

I'm assuming OTS 8 has more stretch in the octaves than say OTS 4.  Do I
have this backwards or am I missing something else?

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
