koechlin was enormously prolific, as the worklist below (by no means exhaustive) suggests. he was highly eclectic in inspiration (nature, the mysterious orient, french folksong, bachian chorale, hellenistic culture, astronomy, hollywood movies, etc.) and musical technique, but the expressive core of his language remained distinct from his contemporaries. at the start of his career he concentrated on songs with orchestral accompaniment, few of which were performed as intended during his lifetime. a recent (2006) recording of a selection (hänssler classic cd93.159) shows he was already master of an individual impressionism deriving less from debussy than from berlioz and fauré. thereafter he concentrated on symphonic poems, chamber and instrumental works.
