If Debussy intended Pelléas et Mélisande as a deliberate anti-Tristan, Donizetti’s L’elisir d’amore perhaps stumbled into the role. Donizetti was of course not responding to Wagner’s opera (which would not be written for another three decades) but to the legend Wagner would also draw on, with results that were rather more... German, shall we say, than the sunlit uplands of L’elisir.
