“In Singin’ in the Rain, Lina Lamont provides both an effective “beard” for Don and Cosmo and a foil, representing both the reason for Don’s “unattached” state and the basis for their mutual contempt for women. Yet the signs are all there to be read for those interested in reading them: Cosmo and Don performing as a burlesque team, in which they sit on each other’s laps and play each other’s violins; Cosmo’s comment to Lina after the premiere of The Royal Rascal, “Yeah, Lina, you looked pretty good for a girl”;30 and their bullying, in “Moses Supposes,” of the fogyish diction coach, figuratively drawn out of his closet only to be ridiculed as an asexual “pansy” who can’t sing and dance (thus both confirming and denying homosexuality at the same time).31 On a broader scale, Kelly’s career as a dancer, offering a more masculinized style of athletic dance (in opposition especially to the stylized grace of Fred Astaire), represented a similar balancing act between, in this case, the feminized occupation of balletic dance and a strong claim of heterosexual masculinity. Significantly, the process of exclusion they use with the diction coach is precisely what Cosmo proposes they apply to Lina in converting The Dueling Cavalier into a musical: “It’s easy to work the numbers. All you have to do is dance around Lina and teach her how to take a bow.” But they also apply the strategy to Kathy, who is only just learning to “dance” in this sense (conveniently so, since Debbie Reynolds had had but little dance training, as noted).32 Early on, we see her dance competently in “All I Do Is Dream of You,” but she then seems extremely tentative in “You Were Meant for Me,” immobile for much of the number, not joining in the singing, and dancing only as Don draws her in (which is, of course, consistent with her character’s development at this point). With “Good Mornin’,” though, she seems to “arrive” as part of the Don-Cosmo team, even though for part of the number she serves as a kind of mannequin—much like the voice teacher in “Moses Supposes,” except that she sings the song proper while Don and Cosmo “improvise” tongue-twisting elaborations between the lines. As the number evolves, their emerging positions within the group become clear. Thus, during their solo clownish dance bits, using their raincoats as props, Kathy and Don present themselves as fetishized love objects, Kathy as an “Island girl” and Don as a matador, while Cosmo dances with a “dummy,” recalling his earlier solo turn in “Make ’em Laugh.”

“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.”
