Ges-Dur
Étude Op. 25, No. 9 in G-flat major, known as the "Butterfly" étude, is an étude by Frédéric Chopin. The title "Butterfly" was not given by Chopin (as is true for all Chopin pieces with such titles); however Arthur Friedheim said, "while some titles were superfluous, this one is inadequate."
