Until his recent retirement, Cantor Davidson was the Nathan Cummings Professor of Nusach at the H.L. Miller Cantorial School, where he taught since 1977 and earned a Doctorate in Sacred Music. Davidson also served as the cantor of Congregation Agudath Jeshurun in Elkins Park, Pennsylvania from 1966 to 2004. Cantor Davidson has also been a prolific composer and arranger. His catalogue contains more than three hundred works, including of dozens of synagogue pieces, songs, choral cantatas, entire services, psalm settings, musical plays, theatrical presentations, instrumental works and a one-act opera based on Isaac B. Singer's story "Gimpel the Fool." His powerful holocaust cantata, "I Never Saw another Butterly," a setting of children's poetry from Terezin, has been performed all over the world. HUC-JIR/New York's School of Sacred Music Choir will perform a selection of his works as Cantor Davidson discusses them. This Master Class is presented through the generous support of a fund established by Cantor Harold Orbach.
