Brahms loved the rich, warm sound of the viola, and created a viola alternative for his Clarinet pieces (as he had earlier for the Horn Trio, Op. 40). Within days of sending the Clarinet Sonatas to his publisher, Brahms sent in alternative parts for viola. (They were published simultaneously in June 1895.) These were certainly commercial transpositions, about which Brahms was always ambivalent, but he did undertake the task himself in these cases and produced well-considered reworkings.
