Schuman went mad. He was kept away from his pregnant wife and collegue, Clara. Young Brahms consoled her with music. He played Schubert’s A Minor piano sonata for her as well as other pieces. And Brahms and Clara continued their professional collaboration during this period. Very sad.

I am reading a bio of Brahms. After reading about this period in his life, I played through the Schubert A Minor piano sonata myself. I like it.
