 Chopin dedicated it to Friederike Müller (1816–1895), one of his favourite pupils, who studied with him for 18 months (1839–1841).Franz Liszt gave her the nickname "Mademoiselle opus quarante-six" ("forty six", the work's opus number, in French).The "Allegro de concert" includes certain devices which reflect a more virtuosic technique than that required by most of his other works.
