[pianotech] ETD stretch vs pure (octaves)

[Richard Brekne]

Hi Duaine

Yes I remember some of that when I was last able to join in as well.  It 
got hard to separate thoughtful posts from hype there for a while :)  
There IS a sense of pureness to be had. And this can be created in a 
variety of ways.... indeed, sometimes what works for one piece of music 
is not quite so wonderful for the next. But all that is very closely 
allied to the whole perspective of partials matching. Whether one does 
this consciously or has some more intuitive approach that brings them 
home is not really so important.

I'm working on a publication about morphing the P-12ths approach I've 
been using these past 10 + years or so with octave types.  I'll post a 
link to it when I get it done.  It works really well in just about every 
situation.... predictably enough because it utilizes the exact aural 
testing methods, (translated to visual feedback of Tune-labs screen) 
that has pretty much always automatically taken care of any pianos 
inharmonicity.  And you get to use your Ears right along side to tweak 
as you go.

Cheers

    Richard,

    Thank you... I've been thinking that all along. However, there was so
    much talk a while back about <<pure>> octaves and the next time I used
    my RCT, I saw the selectable amount of stretch, it didn't make sense any
    more.

    To recap, so when I do a real check of octaves ~(A2 + A3), I just adjust
    based on what sounds good on that piano.

    Thanks, again,
    Duaine
