24 Pièces en style libre

Historical context

Vierne wrote his 24 Pièces en style libre - twenty-four short pieces in free style - in 1913-14, publishing them in two books in 1914. Unlike the towering symphonies, they are scored for organ or harmonium and are deliberately modest in scale and difficulty, conceived so that they could be played on the smaller instruments found in ordinary churches and homes. The twenty-four pieces run systematically through all the major and minor keys and range across a whole gallery of characters - Préambule, Cortège, Canon, Berceuse, Carillon, Postlude and many more.
