 12 in B minor is an étude for piano written by composer Franz Liszt.It has the programmatic title "Chasse-neige" ("impetuous wind which raises whirls of snow"), and is the 12th and last of the Transcendental Études.The étude is a study in tremolos but contains many other difficulties like wide jumps and fast chromatic scales, and it requires a very gentle and soft touch in the beginning.
