?? Taking Mozart as a convenient example (since I have CD's to hand
from the same performer and orchestra)

Concerto 26 for piano and orchestra K.537 - the "Coronation" !=
Rondo for piano and orchstra K.382 - though both are in D major.

Piano concerto 18 != piano concerto 27 though both are in B flat major

_Which_ well tempered temperaments? [Shades of Walter/Wendy Carlos and
Switched on Bach 2000 :) ]
