P12 in Tunelab Pro

[Richard Brekne]

Hi Dave

Ah yes... well the only one tossing a P12th tuning around on the list 
these past couple years has been myself with my Tunelab rendering.  
Bernhard has jumped in more recently and claims origin of  the idea, but 
I rather think it predates him as well. No biggie really one way or the 
other as I think its probably one of the more natural tendencies in 
tuning to get 5th variants as quite as possible. More then likely there 
have been folks doing more or less this kind of thing for quite some time.

The thing about insuring as pure a 12th as possible for the entire 
tenor/treble region is that it takes over as the determinant for the 
tuning, aligning octaves as a consequence, not directly.

Ric,

Can't say as I learned one precisely. I got some advice from a mentor on 
this list, used much of it, and it seems to work. But I was curious 
where "it" originated(not realizing many different theories were being 
tossed about...:-). I jumped into this discussion a little late, and 
have since backtracked and read most of the posts. So I'm guilty of not 
actually having followed the first part of the thread. My method--and I 
blame nobody else-- 5ths and 12s as close to perfect as possible without 
making the octaves unlistenable, particularly in the treble from g5 up.. 
I do it by ear, as in the end, it is judged by ears. Don't know where it 
originated, but I am curious... I will try a P12 tuning and see how it 
differs. I think what we're all after is a really an open, expansive 
sound. I don't know how else to describe it. There seem to be many ways 
to achieve this.
