Stefan Kisielewski, nicknames Kisiel, Julia Hołyńska, Teodor Klon, Tomasz Staliński, was a Polish writer, publicist, composer and politician, and one of the members of Znak, one of the founders of the Unia Polityki Realnej, the Polish libertarian and conservative political party.

Neoclassicism in music was a twentieth-century trend, particularly current in the interwar period, in which composers sought to return to aesthetic precepts associated with the broadly defined concept of "classicism", namely order, balance, clarity, economy, and emotional restraint. As such, neoclassicism was a reaction against the unrestrained emotionalism and perceived formlessness of late Romanticism, as well as a "call to order" after the experimental ferment of the first two decades of the twentieth century. The neoclassical impulse found its expression in such features as the use of pared-down performing forces, an emphasis on rhythm and on contrapuntal texture, an updated or expanded tonal harmony, and a concentration on absolute music as opposed to Romantic program music.
