Asunto: Re: Perfect Fifths Tuning

--------------------------------------------------------------------------------

Dividing 3/2 into 7 is an interesting idea that I'd thought about some
time ago. I had previously dismissed as being basically the same thing
as 12-tet (in which the fifths are almost just), but with the octave
stretched a bit. It would be interesting though to see if there are
any properties of this scale that have been overlooked, or to run some
A/B comparisons to hear the difference musically between the two.

-MikeI agree Mike. As I told you, this idea and complementary details were defined in a short period of time.-----------------------------------------------------------------------Mike,Now that my "discovery" and calculations were done for nothing what about hiring a fellow to make a list ofscale discoveries since the XVII century? This way I don´t start investigating already patented subjects. Marpurg was the first with Piagui II, though I doubt that he got Piagui II because he never calculated the Piagui P and K semitone factors that are the exclusive doors to enter to the Piagui system. Now Cordierin France put me out of the "crowded" perfect fifths scene. With these experiencies there is no future for the inventors. Right?-------------------------------------------------------------------------------------------------------------------------------In my preceding message related to the perfect fifths tuning I included the twelve relative frequencies with respect to C = 1. One error was found in F#:
F# = 1,41558300612. The red number 0 must be replaced by 8.

-- The 88 tone frequencies given for the piano (Hz) seem to be correct. This set obviously does not consider the needed adjustments for cancelling the ear imperfection.
