In this article I wish to consider a particular instance of the world-disclosing abilities of music in cinema: its capacity to flesh out states and events in a fictional world.This is the celebrated ostinato motive underpinning the first shark attack in Jaws (1975), shown in Ex. 1 in its stripped-down, most widely remembered and, indeed, iconic version.An exploitative 'horror flick', Jaws misrepresents sharks and their behaviour. Ironically, such a misrepresentation is contingent on the ability of music to represent. Throughout the film, to adopt Kendall Walton's terminology, John Williams's notorious motive makes it fictional that the shark is about -and about to attack. 1 Jerrold Levinson writes (1996, p. 261) that 'the musical "shark" motto is the only reliable signifier of the shark and so has an ineliminable fact-conveying function'. Kevin J. Donnelly, in his discussion of the power of music to convey presence, claims of Williams's music that it does not merely signify the presence of the shark -'it is its presence' (Donnelly 2005, p. 93). Although they focus on different aspects of the score's impact, these statements are symptomatic of a broad agreement that the music of Jaws is representational. Taking stock of this consensus, my intention in this article is to investigate the conditions of the score's widely acknowledged representational force. In particular, I will review in some detail the sequence of the first shark attack and argue that selective attention is the pivot around which representational film music of the kind employed in Jaws revolves. Revisiting the remarkable early stages of the film will also bring to light an element of representational excess in the music, which I will go on to interpret as an attempt at capturing the world as seen, as it were, from the shark's own vantage point.Let me begin by reviewing the moment in which the shark attacks 'the first victim', as the relevant music cue calls her. 2 The attack is shown in a handful of simple yet terrifying shots that exemplify the moments, and attendant moods, which define the horror genre: tension (or suspense), shock and horror-inducing action. 3 The music reflects this trajectory: a suspenseful motive is followed by a shocking stinger and finally a climactic tutti. 4 The first image is a moving shot of a young woman, Chrissie, seen from under the water -a shot that we gradually associate with the point of view of the approaching shark (Figs 1-3). For this image, Williams has devised an ostinato motive consisting of the alternation of two notes, moving a minor second apart (E-F) at moderate speed, and played both staccato and marcato in a low register (Ex. 2). This is interrupted by a tone cluster, its sinister sonority tempered by a hint of Figs. 1-4 The shark approaches Chrissie Ex. 2 Musical cue which accompanies Figs 1-4 308 giorgio biancorossoMusic Analysis, 29/i-ii-iii (2010)
