A beautiful, transcendent setting of the Latin text 'O mysterium ineffabile' ('O ineffable mystery'), a text which exclaims the greatness and divinity of the eucharistic feast. Commissioned in 2023 by Cantiamo Sonoma, California, this accessible but captivating setting by Norwegian composer Kim André Arnesen employs the composer's characteristic singable melodies and rich harmonies, and is suitable for intermediate choirs.
