Ben Schwarz reflects on the demise of the Songbook, "a notional catalogue of classic popular songs, a body of refined, complex work that stands at the apogee of this country’s civilization, mostly written for the musical theater from roughly the 1920s to the 1950s":
The Songbook, a product of a fleeting set of cultural circumstances when popular, sophisticated music was aimed at musically knowledgeable adults, was the crucial wellspring of jazz. Both jazz and its progenitor are worthy of radical—indeed, reactionary—efforts to preserve them. But despite [musician and scholar Ted] Gioia’s ardency, there is no reason to believe that jazz can be a living, evolving art form decades after its major source—and the source that linked it to the main currents of popular culture and sentiment—has dried up. Jazz, like the Songbook, is a relic—and as such, in 2012 it cannot have, as Gioia wishes for it, an "expansive and adaptive repertoire."
