The composition "1.X.1905", commonly known as "Sonata", was developed during the autumn of 1905, at the height of the unrest between the Czech-speaking and German-speaking communities of Brno, home of Janá?ek. In response to the violent death of a Czech worker, Janá?ek wrote a three-part piano composition, originally entitled "From the Street, October 1, 1905". Dissatisfied with this work, he would, before the first execution, first burn the third movement in the chimney, then threw the two remaining movements in the Moldau. A copy of these first two movements, according to which the first edition was later published, has also disappeared. This is why the G. Henle and Universal Edition urtext edition is based exclusively on its first publication published in 1924, carefully analyzed and commented on for this edition by the expert Janá?ek Ji?í Zahrádka.
