The piano cycle titled Borová celebrates a village near the composer’s birthplace; in the manuscript, it is originally titled Polky 1–7, and the collective title Borová was added later for publication. Martinů began to work on the composition in 1929 in Paris. He completed it during August and September 1930 in Polička. The autograph includes the dedication “To Mrs. Anna Špačková in Paris, May 1931.” Polka No. 1 has also been arranged for a small orchestra (see H 195 A). The cycle continues the series of Czech dances begun with Three Czech Dances for Piano, H 154, in a somewhat simplified and less demanding way.
