At Choral Evensong on April 2, guest organist Dr. Patrick Scott (from the Cathedral of St. Philip in Atlanta) will improvise in the French alternatum tradition. That is, members of the choir will sing to plainsong a verse of the Magnificat and Nunc dimittis, and then the organist will improvise the next verse. This movement back and forth between the choir and organ will continue until the end of each of these canticles. A winner of the 2014 American Guild of Organists Competition in Organ Improvisation, and a student of Dr. Gerre Hancock, Dr. Scott is recognized as one of the country’s leading improvisers on the organ. He will play a recital beginning at 4:40 and then accompany the service beginning at 5:00 p.m.
