Transcendental Etude No. 12 in B flat minor is an étude for piano written by composer Franz Liszt. It has the programmatic title "Chasse-Neige", (literally "snow storm") and is the 12th and last of the Transcendental Etudes. The etude 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 more difficult Transcendental Etudes.
Ferruccio Busoni stated that this is the greatest, most accurate example of program music, or 'poetised music.' He described the work as "a sublime and steady fall of snow which gradually buries landscape and people".[1]
