One of my early childhood recollections in Jerusalem during the 1973 YomKippur War is how my close playmate from the apartment next door froze in her place when the alarm siren sounded instead of rushing down to the shelter. 1 It turned out that she confused the rising and falling sound of the siren activated during times of emergency with the steady siren sounded on memorial days, when the whole country is brought to a standstill for a moment of silent communion with the dead. In what follows I suggest that underlying my friend's naive mistake is more than simply a matter of inexperience, but rather a deep-rooted association between modes of national emergency and modes of collective commemoration in Israeli-Zionist culture. I shall do so by analyzing a site of music production, which, on the face of it, is far removed from the sounds of sirens, that of radio broadcasting. Informed by an ethnographic study of national and regional radio stations in Israel (Kaplan 2008b), I examine how the growing use of music programming presents new ways for engineering national identification. 2 The structure of Israel's radio scene and its music broadcasting policies regulate collective time in a uniform manner, attempting to abruptly alter the public mood in response to national events, in a sense extending the function of the siren. Alternating between ordinary life and times of commemoration or emergency this occasioning of collective time follows Jewish-Zionist temporal regimes perceived as sacred. Consequently, it produces a parallel between times of emergency and sacred time. I shall argue that times of emergency are represented through and subordinated to sacred, mythic
