Chopin's Piano Concerto No. 2 in F minor, Op. 21 was actually composed before his first concerto (in E minor) but published later, hence the numbering. The exquisite Larghetto movement is often described as a romantic, nocturnal song without words, showcasing Chopin's lyrical genius. It is believed to be inspired by the composer's secret love for a fellow student at the Warsaw Conservatory, Konstancja Gładkowska.
