For choir of four-part mixed voices. The original published score states “with organ accompaniment ad libitum.”
Messiaen later in life designated the work for mixed choir a cappella, but the score was not revised.
Thus the piece is often performed without accompaniment.
The text is by St. Thomas Aquinas (1225-1274), used as an antiphon for the feast of Corpus Christi.
