Debussy’s orchestral works are much loved for their exquisite orchestrations, poetically nuanced harmonies and almost magical evocations of time and place. He achieved his first significant success in 1900 with Nocturnes , which portrays in three movements clouds reflected in the sea, holiday festivals in the Bois de Boulogne and the fatally seductive song of the Sirens. The Pelléas et Mélisande Symphony was derived by Marius Constant from the orchestral episodes of Debussy’s famous opera, while the Trois Études are heard in a revealing orchestration of the piano originals by the contemporary Swiss composer, Michael Jarrell.
