Have just returned from Lohengrin. A good opera, very good, but I place it below Tannhäuser and even The Flying Dutchman. The other day I visited a now-convalescent Myaskovsky and met there another officer who is also a musician. I have just met him again and had a talk with him. I said that there is much more material in Tannhäuser; he said that this is because Tannhäuser is a finished work of art while Lohengrin is, so to say, a sketch for the Grail, and it is very possible that Wagner put a great deal more into the first than he did into the second.
