David writes: << Just to add, there is also a Beethoven Sonata in F# and many Chopin pieces in 4 and 5 flats, not to mention the Brahms B major Trio, that I personally prefer in ET. >> 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).
