Known as Étude Revolutionary, Chopin Étude Op 10, No. 12 in C minor is dedicated “à son ami Franz Liszt” (“to his friend Franz Liszt”). The 12th Étude appeared around the same time as the November Uprising in 1831 and its first chord sounds like a gunshot. Frédéric Chopin poured his emotions on the matter into many pieces that he composed at that time, the Revolutionary Étude being the most notable example. – Vladimir Horowitz
