Chopin’s output for piano falls in the majority of cases into specific categories: mazurkas, polonaises, nocturnes etc. There are in fact very few pieces that defy such classification. The more important of them, though varying in character, have been combined to form this present volume. Those works published during Chopin’s lifetime are arranged according to opus numbers. They are followed by the variations, issued posthumously, on the song “Der Schweizerbub” (“The Swiss Lad”) together with the Three Ecossaises Op. 72 No. 3.
