Saturday, January 12:
Around lunchtime R. plays me what he has composed of Amfortas's Lament; the modulation on the words "nach ihm" ["after him"] occupied him the whole morning. Talking about it at lunch, he says, "I sit there, looking at your portrait, [illegible word], I am an idiotic composer, it's all such an effort."
Very cold weather. Worry about Fidi, whose room has become damp; we move him to the nursery. In the evening the history of the Arabs. Then R. sings us some of the recitatives from Jessonda, in which the "interchange of feeling" and similar absurdities make us laugh a lot. "Such things never occur with French composers," says R.
