Nobody is perfect. Good to know. And that’s also a point in a discussion between Kafka Tamura and Oshima in Kafka am Strand (on the Shore, (海辺のカフカ, Umibe no Kafuka). They talk about Schuberts sonata while Oshima is driving his car at 140 km/h (87 miles/h) on there way to Oshimas domicile in the mountains. Oshima thinks, that there is no pianist in the world, that can play the difficult all parts in d-dur in four sentences, maybe two in a row. “Weil es das Schwierigste ist, die Sonaten von Franz Schubert vollkommen zu interpretieren.” (p. 154 g.e., most difficulties lay in the interpretation of Schuberts sonates.). Kafka himself is bored by listening to that music. As Oshima mentioned: you have to get a feeling to listen to that kind of music, get used to it. That kind of feeling needs pratice in listening to it - over and over again.
Because there is no title told in the story, we are here listening to Alfred Brendel. The pianist is playing Schubert Sonata D. 958 (1988).
