Waltz in E minor (Chopin)
It was the first of Chopin's posthumously published waltzes not to be given an opus number. It appears in Brown's catalogue as B. 56, in Kobylańska's catalogue as KK IVa/15, and in Chomiński's as P1/15. It was composed shortly before Chopin left Poland at the age of 20. Although this is the final (fourteenth) waltz in the older editions of Chopin (other waltzes being included in more recent editions), it is believed to have been composed before any of the waltzes published in Chopin's lifetime.
