Book excerpt: Paul Dukas wrote about Debussy that the strongest influence he experienced was that of the poets, not that of the musicians. This book undertakes to demonstrate that thesis by studying Debussy's settings of songs by Banville, Verlaine, Baudelaire, Mallarmé, Louÿs, and Debussy himself. A particular insight may be gained in the comparison of six poems by Verlaine set to music by both Fauré and Debussy. The book includes a poetic/musical analysis of Debussy's Prelude to the Afternoon of a Faun, based on the poem by Mallarmé.
