Carl Maria von Weber was a composer of the early romantic, meaning he came after Beethoven but before Chopin/Liszt/Mendelssohn/Wagner/Schumann. Basically a similar timeframe to Schubert. He was prolific, wrote in just about every format/genre, and was very popular in his lifetime. For whatever reason, he is basically forgotten today and I never see him mentioned or hear performances of his works.
I have recently been looking at his first piano sonata in C major, and I think it's a very nice piece. Maybe not the most profound music ever written, but definitely well-written and effective. It seems like some pianists perform the 4th movement as a standalone piece (in my view, this is a big no-no for a sonata) but the only famous pianist to record the whole sonata was Arrau.
Is anyone here familiar with the works of Weber? Has anyone played anything by him? Why has he been so ignored and not included in the standard repertoire?
