In a letter to his friend Erwin Rohde in October 1868, Nietzsche described his reaction to Tristan's prelude: "I simply cannot bring myself to remain critically aloof from this music; every nerve in me is atwitch, and it has been a long time since I had such a lasting sense of ecstasy as with this overture".
Nunha carta ao seu amigo Erwin Rohde en outubro de 1868, Nietzsche describiu a súa reacción ao Preludio de Tristan: "Eu simplemente non me atrevo a permanecer criticamente apartado desta música; cada nervio meu está encantado, e ten pasado moito tempo dende que tiven unha sensación de éxtase tan duradeira como con esta abertura".
