Ulvi Yurtsever quotes Charles Rosen:
>the coda to the first movement of Beethoven's Sonata in D Major,
>opus 10, no. 3, is exactly the same as the beginning of the song "How
>Dry I Am," and is also the exact inversion of the opening of the F
>major second theme in the finale of Brahms's Sonata for Piano, opus 5.
Which reminds me that the transfiguration theme from R. Strauss's Death
and Transfiguration is the inversion of the big opening theme from
Tchaikovsky's 1st Piano Concerto...
