Die Soldaten
Rather than engaging a librettist to adapt the original play for him (as was customary), Debussy chose to set the text directly, making only a number of cuts. Maeterlinck's play was in prose rather than verse. Russian composers, notably Mussorgsky (whom Debussy admired), had experimented with setting prose opera libretti in the 1860s, but this was highly unusual in France (or Italy or Germany). Debussy's example influenced many later composers who edited their own libretti from existing prose plays, e.g. Richard Strauss' "Salome", Alban Berg's "Wozzeck" and Bernd Alois Zimmermann's "Die Soldaten".
