Étude Op. 25, No. 11, in minor, often referred to as the Winter Wind, is a solo piano technical [bad word] by Frédéric Chopin in 1836. It was first published together with all études of Opus 25 in 1837, in France, Germany, and England. The first French edition indicates [bad word] time time signature, but the manuscript and the first German edition both feature cut time.[1] The first four bars that characterize the melody were added just before publication at the advice of Charles A. Hoffmann, a friend.
