The musical influence from Respighi's stay in Germany is discernable in his second operatic work, "Semirâma". The opera premiered in Bologna in November 1910 to considerable success; two years later, critic Giannotto Bastianelli wrote that the piece marked a transition in Respighi's style from verismo to Decadentism and praised his use of rich polyphony. Working on the opera, however, left Respighi exhausted and he wrote each individual score by hand to save money. At the post-performance banquet, the composer fell asleep. It is thought that Respighi's inconsistent sleeping patterns throughout his life may have been caused by narcolepsy.
