Hear a 45-minute program of early music in the small, English Gothic–style sanctuary tucked off Trinity’s nave. Trinity Choir and organist Avi Stein perform Musikalische Exequien, op. 7, by the great German composer Heinrich Schütz — a funeral piece that parallels the traditional Latin requiem in expressing mortality, comfort, and hope. The collection of motets, one of the finest choral cycles of the 17th century, had a far-reaching impact. Bach’s Der Geist hilft unser Schwachheit auf, an homage to this style, is also on the program. Repeated at 6:30pm.
