The Chrism Mass is the annual celebration where the archbishop blesses the oils for use throughout the archdiocese and the priests renew their vows of service. It is one of the events that generally fills the Cathedral every year. As with other special diocesan celebrations, these are people that have chosen to be here, so are willing to sing and participate. Here’s the responsorial psalm (from the Audubon Park Psalter)recorded by my iPhone placed on the organ console in the balcony. Brass are to my right. Choir is on the left, and the cantor is in the pulpit half-way down the building.
The music for this composition is included in the Feasts and Solemnities volume of the Audubon Park Psalter.
