Chopin published his first études as his Op. 10 in 1833 when he was just 23 years old. By that time, however, he had developed a considerable reputation in his native Poland and in the salons of Paris.
He decided to dedicate Op. 10 “to my friend, Franz Liszt,” a fellow pianist-composer, two years Chopin’s junior, who would compose his own Transcendental Études a bit later.
Chopin composed the Op. 25 études, a set of 12, several years later, which he dedicated to his close friend Marie d’Agoult; He published his last entries into the genre, 3 Nouvelles étude, in 1839 as a part of a larger instructional volume titled Méthode des méthodes de piano.
