O Ildephonse is a double-choir motet published in 1600. It is arranged for SSAT / SATB recorders. The separation and imitation between the two unequal choirs makes this excellent for recorder orchestras. Ideally, this sacred motet could be performed from opposing choir lofts in a large cathedral. Conductors score and individual parts. Rich and resounding piece for recorder orchestras, workshops, and recorder society meetings.
