Book excerpt: Throughout history, music has been a fixture of Jewish religious life. Musical references appear in biblical accounts of the Red Sea crossing and King Solomon's coronation, and music continues to play a central role in virtually every Jewish occasion. Through 100 brief chapters, this volume considers theoretical approaches to the study of Jewish sacred music. Topics include the diversity of Jewish music, the interaction of music and identity, the emotional and spiritual impact of worship music, the text-tone relationship, the musical component of Jewish holidays, and the varied ways prayer-songs are performed. These distillations of complex topics invite a fuller appreciation of synagogue song and an understanding of the ubiquitous presence of music in Jewish worship.
