Despite its “regional” label, the 1937 Exposition offered meagre support for folk-related art music written by regionalists, suggesting that the tempering of folk music’s power was just as important here as in its popular sung and danced forms. Consistently across the century from the 1830s, provincial career paths for composers offered many more opportunities for decentralized or centralist activity (secular or as a maître de chapelle) than for regionalist expression, and the Schola Cantorum was not the catalyst for change to the extent that has hitherto been assumed. Discussion of the influence of the “Russian Five” on French music, and the contrasting ways regions (native and adoptive) are presented in new music, leads to case studies of operas by Bruneau, Séverac, Ropartz, Canteloube, and Leroux to show how French local and regionalist content played out in Paris during periods of changing nationalist intensity, including during World War I. The allegorical tactics of creative anachronism (Ropartz) prompt a broader discussion about the folk-historical nexus in French music from Chabrier to Poulenc, underpinned via modality. This nexus is what explains why France emerges with one of the few European modernisms to eschew folk sources except as folded into an upper-class patrimoine—the balletic dance that underpins much French neoclassicism.
