Transcendental Étude No. 12 in B♭ minor is an étude for piano written by composer Franz Liszt. It has the programmatic title "Chasse-Neige", 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. The piece gradually builds up to a powerful climax. It is one of the most difficult Transcendental Études, being ranked 9 out of 9 by publisher G. Henle Verlag, one of the six in the series to receive the highest possible difficulty ranking.
