Juli us Schlitterlau, writing afterwards in her diary: "The piece is splendid, fresh and passionate, just as I like it!" Even Schumann himself was impressed with his new composition. He particularly drew the publisher KistnerŒÍs attentionto the "brilliant allegro", whose solo part is indeed sovirtuosic that opus 70 is one of the showpieces for horn players even t oday.?
