ピエトロ・マスカーニ
Guglielmo Ratcliff is a tragic opera in four acts by Pietro Mascagni to an Italian libretto by Andrea Maffei, translated from the German play "Wilhelm Ratcliff" (1822) by Heinrich Heine. Mascagni had substantially finished the composition of "Ratcliff" before the success of his first opera, "Cavalleria rusticana".
