Chopin Prelude No 8, in F Sharp Minor, counters the calm simplicity of the seventh with a broad stream of sonority of peculiar beauty, diffused in rising and falling waves of airy figuration. Among its admirers was Witold Lutosławski, who called it a ‘wonder’. Chopin 24 Preludes, Op. 28, are a set of short pieces for the piano, one in each of the twenty-four keys, originally published in 1839. Chopin wrote them between 1835 and 1839, partly at Valldemossa, Majorca, where he spent the winter of 1838–39 and where he had fled with George Sand and her children to escape the damp Paris weather.
