Wilhelm Mohr's Psalm 24 "Machet die Tore weit" (Lift up your heads, O ye gates) op. 3 for mixed choir, large orchestra and organ with children's choir ad lib. is a powerful music in the late romantic tradition. Its grandly structured line leads finally in the well known Advent carol "Macht hoch die Tür" (Open the Door High), to sing optionally by a children's choir but even accompanied by the congregation.
