The dramatic strategy of the show provides a simple and effective means to blend melodrama with farce (which Sondheim claims as his “two favorite forms of theatre because … they are obverse sides of the same coin”).37 Starkly put, the show develops a pattern of first scaring the hell out of its audience and then rescuing the situation through humor, each time by introducing Mrs. Lovett into a situation saturated with Sweeney Todd’s wrenching angst. This scare-rescue pattern happens twice to great effect, at the beginning and end of Act I, but its real payoff is the devastating conclusion, where there is no comic rescue. The denial of this previous pattern greatly intensifies the darkness of the supremely bleak ending, making the show’s musical profile seem operatic to Broadway audiences even though, ironically in this respect, the denouement unfolds with only intermittent singing.38 But the musical dimension of the show is also deliberately operatic, as it interweaves, Wagner-like, a host of recurring motives, mostly related to each other through a common origin in the Dies Irae, from the Catholic requiem mass. The Dies Irae (literally, “Day of Wrath”; see example 7.1) was taken up as a symbol of death and retribution in music throughout the nineteenth century and continuing into the twentieth (the most important early such use was by Berlioz in his 1830 Symphonie fantastique). Most scene changes bring back “The Ballad of Sweeney Todd,” which includes both fast and slow versions of the Dies Irae (example 7.1) and builds up to a frenetic, obsessive chorus of “Sweeney, Sweeney.
