Ah yes, Beethoven composed one sonata in F#, and it is, by most accounts
I have gotten from musicologists, somewhat odd. I had one accomplished
pianist try a WT with this piece and she remarked that it was the first time that
it had ever made harmonic sense to her!
Chopin's music makes much use of the juxtapostion of a very active
harmony against a pure melodic line,(those fifths in the remote keys are pure). Our
recording in a DeMorgan temperament(effectively a reversed order well
temperament), was strictly an academic excercise, but many people have thought it
sounded really fine, too.
When we compile a list of classical compositions, by key, we see that
usage of a key depends on where on the circle of fifths it is, with the key of C
used most, and the key of F# used least. The order of ascent in usage mimics
the amount of tempering in a WT, too.
When compared to the tempering of WT's , we see that prevelance of key
usage directly correlates to the amount of tempering in the tonic key. This
linkage was most pronounced prior to 1700, where we see the meantone wolf keys
completely avoided by most. As the 18-19th centuries passed, we see a general
trend of less and less contrast in the temperaments that directly correlates
with the increasing democracy of key usage. By the time of Rachmaninoff, Ravel,
Gershwin, etc. the temperament has become equal, and the use of all 12 keys
almost even. However, Beethoven, Mozart, Haydn and otheres of their day
certainly did not use the remote keys nearly as much as they did ones with less
dissonance.
Anybody care to offer an explanation of why composers chose the keys that
they did, if not differences in temperament? (Rita Steblin's book should be
required reading for all tuners).
