Jonathan L. Friedmann and John F. Guest document and analyze Sonderling's experience and expression of Judaism through music. Rabbi Sonderling's vision yielded liturgical commissions from exiled Viennese Jewish composers who arrived in Los Angeles in the 1930s and 1940s. Through these musical settings, activities at the Fairfax Temple, and involvement with the Los Angeles campus of the Hebrew Union College-Jewish Institute of Religion, Sonderling made an indelible mark on the city's Jewish community and the wider musical world.
Songs of Sonderling focuses on the commissions Sonderling made from 1938 to 1945: Ernst Toch's Cantata of the Bitter Herbs, Arnold Schoenberg's Kol Nidre, Erich Wolfgang Korngold's A Passover Psalm and Prayer, and Eric Zeisl's Requiem Ebraico. Through musical analyses and an examination of Sonderling's career in Los Angeles, Friedmann and Guest contribute to the study of Jewish liturgical music, to Jewish history in the American West, to Jewish identity in the twentieth century, and to Jewish diaspora writ large.
