This collection of essays by scholars of nineteenth- and early twentieth-century French music has been assembled in homage to the influential and inspirational French musicologist FranAois Lesure who died in 2001. Lesure's immense erudition was legendary and spanned music from the sixteenth to the twentieth century. Two French composers who were particular foci in his scholarship were Berlioz and Debussy and this collection is based on scholarship around these two composers and the sources, contexts and legacies relating to their work.
