FartBlakey: as far as I know, all of Hildegard's compositions were written for her monastery's officium services. So to answer your question: they were composed for monastic life, not for Symphonia armonie... which only collected them.
was the symphonia armonie celestium revelationum intended more as an album or a compilation? by which i mean were the songs listed in it composed specifically for it or not? sorry for the retarded phrasing of this question
