The composition Three Czech Dances for piano (Obkročák – Dupák – Polka) was completed on November 9, 1926, in Paris, around the time when he first met Charlotte Quennehen. It was his first explicit musical reminiscence of home. The autograph copy of Obkročák, dedicated to Jan Heřman, is dated “Paris December 1926”. The premiere took place on March 7, 1927, in Paris, performed by Jane Mortier.
