Thalberg performed in Brussels in fall 1840. He then travelled to Frankfurt-am-Main where he stayed until January 1841. It had been announced that Thalberg would give concerts in Paris again in spring 1841, but he changed his plans. In Frankfurt he only took part in a charity concert on 15 January 1841, playing his fantasies on "La Donna del Lago" and "Les Huguenots". He was busily composing new works; his "Second Don Giovanni Fantasy" op.42 and the fantasy op.51 on Rossini's "Semiramide" date from this time.
