These Three Mazurkas, Op. 63, are dedicated to Countess Laura Czosnowska. This collection is the last set of mazurkas published during Chopin's lifetime.

The first piece, in B major, is marked Vivace. It is a mazur with characteristics of an oberek. A Kujawiak is inserted midway through the piece. The middle section modulates to A major.

The second piece, in F minor, is marked Lento. It is a nocturne-like Kujawiak. The middle section becomes a mazur. Throughout the entire piece, altered chords are frequently used.

The third piece, in C-sharp minor, is an Allegretto Kujawiak. The middle section is a typical mazur. In the coda, the technique of octave canon is employed, creating a fantastical atmosphere. Similar to the preceding piece, it possesses a nocturne-like character.
