Marcel Dupré, a student of Charles-Marie Widor and Alexandre Guilmant, was one of the great French organists of the 20th century. He performed over 2000 recitals around the world during his life and was famous for his improvisations. From 1906 until his death, he was organist at the church of St Sulpice, Paris. While most of his compositions are for the organ, he did write for other media as well. This beautiful setting of the familiar Latin text was published in 1917 as one of his four motets, the others being for chorus.
