The Des Moines Vocal Arts Ensemble will close its season with “A Celebration of Psalms.” Western choral music is frequently composed to texts from Christian traditions, and this program features music written to Psalms, a majority of which are knows as the “Songs of David.” The English word psalm is from the Greed word psalmos, which is a translation of the Hebrew word mizmor, meaning “song.” The 150 Psalm texts express a variety of emotions and have provided inspiration to composers from ancient to modern times. The concert will feature Leonard Bernstein’s Chichester Psalms, a work commissioned for the Chichester (England) Choral Festival in 1965.
