In a career spanning 45 years, David Cronenberg’s filmography includes 22 films. Since 1979, Howard Shore has scored 15 of them. Though Cronenberg’s world is well known now, the weight of the contribution of his composer remains largely unmeasured. And this, despite the fact that music seems to play a primary role in the director’s process since Shore is involved very early on. This unusually early involvement of the composer is indicative of the central role held by Shore and his music: how to define it ? This paper does not seek to determine the functions of film music. Instead, it explores the creative processes that give rise to it. The creative processes of Cronenberg and Shore, who “learned everything together,” thus have similar characteristics. More precisely, they present common artistic figures that gather them into a single artistic vision: the autodidact, the experimenter, the improviser, the painter/sculptor, and the artist-artisan.
