World War I, however, was a nightmare for Wolf-Ferrari. The young composer, who had been dividing his time between Munich and Venice, suddenly found his two countries at war with each other. With the outbreak of the War, he moved to Zurich and composed much less, though he still wrote another comedy, Gli amanti sposi (1916). A new melancholy vein appeared in his post-war work; his operas grew darker and more emotionally complex.
