Franz Liszt transcribed all nine Beethoven symphonies for solo piano, and although he was known to perform at least some of them in concert, they were published with the amateur pianist in mind.
Just how many amateurs were actually capable of playing them is open to question. Listen to the Symphony No. 7 this Thursday and see what you think. After that, we'll have music from the Italian Baroque, and we'll conclude with a virtuoso work for cello by 20th-century Hungarian composer Zoltan Kodaly.
