As a noted composer and critic, and later an editor and composition teacher, Paul Dukas (1865-1935) was a major figure in fin-de-siecle and early twentieth-century French music. Although his catalogue of published scores was relatively modest in quantity, he was internationally recognised as an artist and intellectual of distinction who contributed significantly to Parisian musical cultures and critical debates as they evolved from the 1890s until the 1930s Moving in the same circles as Debussy and Faure, as well as networking with trailblazers such as the Ballets Russes director Sergei Diaghilev and the conductor Serge Koussevitzky, Dukas created works that reflect French sensibilities but also resonate with transnational audiences. L'Apprenti sorcier is still his best-known work, while the opera Ariane et Barbe-Bleue has been revived and remains relevant for the twenty-first century. Works such as the Piano Sonata and the ballet La Peri respectively exemplify the twin attractions of tradition and progress for the composer. Intensely self-critical, however, he ended up destroying many of his scores. This book is the first full-length Anglophone study of Dukas. It perceives his critical essays as a form of creative, philosophical thought that synthesised the riches of the Parisian music scene yet also represented the formation and development of his own artistic voice. Investigating Dukas's interrelated identities as composer and critic, it seeks to explain his broad aesthetic motivations and artistic agenda
