The pianist's annual solo recital opens up 'small wonders' by Chopin, Bartók and Kaprálová. In his 1908 set of Bagatelles, Bartók flirts with diverse musical idioms such as folk music, Debussy-style Impressionism and atonality á-la-Schönberg. Kaprálova's Preludes of 1937, among her most-often performed works, evoke freshness and verve, humor and tenderness (they were dedicated and first performed by her Moravia countryman, Rudolf Firkusny). Lastly, Chopin's iconic set of 24 Preludes, written between 1835 and 1839, includes some of his most heartfelt and beloved music.
