[pianotech] ETD stretch vs pure (octaves)

[Richard Brekne]

Duaine...

I think what everyone is trying to tell you is that there really is no 
such thing as a <<pure>> octave. Nor is there any non relative 
definition of stretch. All octaves in pianos are stretched one way or 
the other.  Our sense of pureness varies  from person to person and has 
to do with just what "stretch" degree we as individuals find most 
pure/pleasing.

Cheers

    Example: how can checking C3 and C4 to be "pure" and "stretched" at the
    same time.
