This Sunday night on “The Lost Chord,” it’s music by French composers better known for their skill as orchestrators of others’ works. We’ll hear original compositions by Henri Rabaud (orchestrator of Gabriel Fauré’s “Dolly Suite”), André Caplet (orchestrator of Claude Debussy’s “Children’s Corner,” “Clair de lune,” “Le Martyre de saint Sébastien,” and “La Boite à joujoux”), Henri Büsser (orchestrator of Debussy’s “Petite Suite” and “Printemps”) and Charles Koechlin (orchestrator of Fauré’s “Pelléas et Mélisande” and Debussy’s “Khamma”).

These musical Cyranos emerge from the shadow of Roxane’s balcony, on “French Connections,” this Sunday night at 10:00 EDT, on WWFM – The Classical Network and wwfm.org.
