The Waltz in C♯ minor is a piano waltz composed by Frédéric Chopin in 1847, the second work of his opus 64 and the companion to the “Minute Waltz” (Op. 64, No. 1). Chopin dedicated this Waltz to Madame Nathaniel de Rothschild.

The Mazurkas, Op. 7 are a set of five mazurkas by Frédéric Chopin. The mazurkas were mostly written in 1830–1831 and were published in 1832.

The first mazurka, set in B-flat major and marked Vivace, is the most well-known mazurka of the set and perhaps, one of Chopin’s most popular mazurkas in general. The second mazurka of the set, A minor is an intimate piece. Despite the Vivo, ma non troppo marking, the mazurka has a slow tempo with a very delicate and melancholy main theme. The third mazurka, in F minor, has a folkish and rustic atmosphere.

The Polonaise in C-sharp minor, Op. 26 No. 1 was composed by Frédéric Chopin in 1836.The Polonaise opens with a fiery Allegro appassionato in C-sharp minor, the primary theme preceded by descending octaves. The section climaxes with a series of virtuosic arpeggio figures which give way to a tender melody. This is then followed by a repetition of the theme. After this opening section, there is a new theme introduced in the enharmonic D-flat major. This new theme is then developed and followed by a new left hand melody, which increases the tension until a repeat of the meno mosso. The piece ends in abrupt quietness.
