Siberian Temperament

As I was reviewing Mark Lindley's article on Pythagorean intonation in the
1980 Groves Dictionary Music, the concluding sentence, which I'll quote
here, caught my eye: "But even though all sophisticated Western composers
and performers since the Renaissance have taken for granted the use of
tempered tuning on normal keyboard instruments, Pythagorean
intonation has persisted in the West as a rustic or provincial practice."
The slightly modified Pythagorean tuning of the piano in Tomsk, with
most of the wolf spread over the fifths Bb to F and F to C may be
a present day example of this practice.
