The Cambridge Companion to Jewish Music
As others in this volume have already noted, the deceptively simple question - What is "Jewish music?" - poses crucial questions about the nature of Jewish identities, musical experiences, and investigatory methods. The problem of "Jewish music" becomes more complicated, however, when combined with other terms that also resist easy postwar classification. From the vantage point of the late twentieth century, what qualifies as "art music"? Does the term refer only to highbrow extensions of serialism, or does it also embrace popular idioms? What does one mean when speaking of music "after 1945" or, more specifically, "Jewish music after 1945"?
