It's a nicely organized exhibition with many Chopin's manuscripts, his correspondence with Eugène Delacroix and George Sand. There are plenty of drawings, many of which emphasize Chopin's constant feeling of being in exile despite the fact that his father was French. He grew up in Poland and most of his work was in one way or another dedicated to Poland.
Fred loved Norma by Bellini, and especially Act 3 of Robert le Diable by Meyerbeer. Since his work is intimately related to the Pleyel pianos, there is a section describing his contact with Pleyel (the son). In one section of the exhibiting hall there is a large Pleyel piano and there was a man playing various pieces by Chopin, who'd explain the details concerning the variety of structures in Chopin's music, relating them to various periods of his life.
