1. X. 1905, sometimes referred to as Piano Sonata 1905 or From the Street, is a piano sonata in two movements written by Leoš Janáček in 1905. He intended the composition to be a tribute to a worker named František Pavlík (1885–1905), who on 1 October 1905 was bayoneted during demonstrations in support for a Czech university in Brno. In the work, Janáček expresses his disapproval of the violent death of the young carpenter. He started to compose it immediately after the incident occurred: the première took place on January 1906 in Brno. Janáček also wrote a third movement, a funeral march, which he cut out and burned shortly before the premiere. He was not satisfied with the rest of the composition either and later tossed the manuscript of the two remaining movements into the river Vltava. He later expressed regret over this. The composition remained lost until 1924 (the year of Janáček’s seventieth birthday), when the pianist who first premiered it announced that she owned a copy.
