To the tuning list,

I made a mistake in my preceding message, in the following lines I used de words "comma fraction" instead of "common fraction":

It is true that between 12 TET constant step size and the variable progression
cell size there is no much difference, however the whole set of 12 TET steps
doesn´t show "comma fraction consonances" like (25/24)= 1.041666...., (9/8)=
1.125 due to the step size of [2^(1/612)]= 1.00113323506. In no case
(1.00113323506)^N gives a number that can be exactly equivalent to a common
fraction provided N is a round number.

Thanks
