The Polonaise No. 6 in A-Flat Major, Op. 53 was called Polonaise Héroïque (heroic) by Frédéric Chopin‘s French lover, the writer Georges Sand. This piece for solo piano, was written in 1842. This composition is one of Chopin’s most admired and has long been a favorite of the classical piano repertoire. The piece requires exceptional piano skills and great virtuosity to be interpreted at a high degree of proficiency. It is also very physically demanding, and according to his student Adolphe Gutmann, Chopin played it more gently than most performers. – Vladimir Horowitz
