Diamond by James McCartney
Partch "otonalities" (i.e. a set of ratios with the same denominator
and changing numerator, i.e. overtone series) run horizontally.
Partch "utonalities" (i.e. a set of ratios with the same numerator and
changing denominator, a.k.a. undertone series) run vertically.
The ratio between a pair of buttons in any two columns is the same for
any row in those columns.
The ratio between a pair of buttons in any two rows is the same for any
column in those rows.
..there must be a less confusing way of stating that...
a set of buttons pressed in one row will be a transposition of the same
columns' buttons pressed in any row.
a set of buttons pressed in one column will be a transposition of the
same rows' buttons pressed in any column.
