[pianotech] [Pianotek] the big discussion

[John Formsma]

David,

I was meaning 4ths in general, and 5ths in general. If one makes all the
temperament 4ths too pure, it will make all the fifths too narrow. John Ross
said his 4ths were "too pure" -- not narrow. My example presupposes that a
person knows that 4ths must be somewhere on the wide side, and fifths must
be somewhere on the narrow side.
