Duration 4 minutes. Schott Music - Digital #Q11265. Published by Schott Music - Digital (S9.Q11265). Latin.Heinrich Poos set to music Canticum Zachariae, one of the three most outstanding ones from St. Luke's Gospel, as a dense, speech-generated setting: The entirely homophonic Benedictus is followed by a contrapuntally ingenious Dona nobis pacem which brings the six-part a-cappella chorus to an evocative end.
