Last night, at the age of 57, I played my very first orchestral New Year's concert. The inspiration for most orchestral New Year's concerts is that of Willy Boskovsky and the Vienna Philharmonic, and there are usually Strauss Waltzes on the program. I have played quartet transcriptions of Strauss Waltzes, but last night was the first time I ever played the viola part of a true Viennese waltz as nature intended (as originally orchestrated).
At the first rehearsal my stand partner told me that one of her past orchestras devoted a whole year to playing Viennese music of all stripes, and the conductor was very meticulous about the way he wanted the after beats to fall. In Viennese fashion the second beat of the three-quarter-time measure falls a fraction of a bit sooner than it would fall when playing the second beat in a non-Viennese waltzes.
I had ample opportunity to experiment, and I found that if I simply let my bow drop to the string from above on the first of the after beats, and then allowed the second after beat to rebound gently on the up-bow stroke, I could get that lilting feeling that I understand to be stylistically appropriate. Since a mixture of gravity and Gemütlichkeit was at play, it seemed to require no effort. No effort is good when your evening is populated mostly by off beats.
Another day, another off-beat.
This morning I played a bunch of waltzes arranged for string quartet. One was Viennese, but most of the pieces in three-quarter time were not. I tried my dropping bow technique on the Strauss, and it worked nicely. Then I tried the dropping bow technique on some non-Viennese waltzes, and it made them feel mannered and awkward.
