Was OnlyPure not P12ths Tunings

[David Ilvedson]

Bernard,

I suggest you write to Don Gilmore, who is developing a self-tuning piano.   That way if your "patented" tuning becomes the standard for that piano you can really rake in the $...

>intervals. That means much more plasure at work and much more precision of
>the tuning. Although in practice, intervals like major thirds or sixths and
>tenths etc. are still useful for control purposes.

>It is not possible to reach this precision with the usual electronic tuning

>The ear has the possibility to analyze pitch and beats nearly in realtime.
>Analogous to the function of the stereocilies and the hair cells of the

>There will be also consequences for the understanding of the musical theory

>the tuning matter from two dimensions to three (and more) dimensions the
>octaves/fifths problem dissappears, the mighty octave must be asked in

>The OnlyPure method is patent pending and registered as mark and will be
