In a letter written in the autumn of 1829, Chopin mentioned to a friend that he had just finished composing an etude "in my own style". Indeed, the author, then nineteen years old, would take distance from the compositions in the genre coming from the pen of his predecessors, with the production of his 24 Études divided into two volumes, Opus 10 (dedicated to Franz Liszt) and Opus 25 (dedicated to Marie d'Agoult, Franz's friend during those years).
Beyond dexterity
Both published in Paris, the first volume in 1833 and the second in 1837, Chopin's Etudes are much more than a set of technically demanding piano pieces aimed at achieving the indispensable dexterity on the instrument. On the contrary, the author's "own style" generated 24 pieces of inexhaustible melodic and harmonic beauty, full of colors, textures, and diverse moods. To these are added three studies without opus number published in 1840.
Etude Opus 10 No 4
Written in the key of C sharp minor, marked presto con fuoco (very fast, fiery), it is one of the most difficult of Opus 10, and perhaps of the entire work, despite its short duration. Nevertheless, it is possible to distinguish in it four sections. After introducing the first theme, the piece progresses rapidly to a second, brief theme at 0:20. The first theme returns at 0:30, and then at 1:15, progressing to the climax at 1:31, followed by the coda, with significant momentum. The piece ends with two dramatic chords, fortissimo.
The rendition is by the outstanding Chinese pianist Bruce (Xiaoyu) Liu.
