With Elsner, composition studies began with the polonaise, but it was immediately followed by rondos and variations (Tomaszewski)
The rondo appeared in the Chopin oeuvre as an autonomous work on five occasions, in his youthful years in Warsaw and subsequently in his early Parisian period (1833). It is this musical form that carries the opus number 1: the Rondo in C minor, by the fifteen-year-old Fryderyk, written and published in 1825. So the rondos composed by Chopin are on the one hand testimony to the young composer acquainting himself with one of the basic classical forms (the rondo of the Viennese Classics: Haydn, Mozart, Beethoven and their imitators), but on the other hand a way of composing in the dazzling and then fashionable style brillant, which for the young pianist Fryderyk was a matter of considerable importance.
