an interesting thing about Barnes

According to Paul Hahn...

...of well temperaments with 2 sizes of 5th (the
most popular kind, it seems), only the pattern
111110100000 lets you know what key you're in from
the size of the major thirds alone after hearing
any V-I progression in the scale. Barnes' 1979
'Bach' tuning is such a well temperament, and
perhaps the most natural one, since its 6 large
fifths are just.
