This chapter demonstrates that Jean Cocteau’s interwar musical-theatrical endeavors with “Les Six” were significant sites for coping with postwar trauma. Letters, diaries, memoirs, and performance reviews illustrate that pieces like Le Bœuf sur le toit et Les Mariés de la Tour Eiffel offered traumatized playwrights, musicians, and audience members opportunities for bodily pleasure and laughter. Examination of archival sources—from period texts on laughter to accounts of humor’s importance for front-line soldiers as well as Dada and Surrealist artists—reveals that absurdist interwar musical theater was intertwined with contemporary ideas concerning the importance of laughter as a tool for emotional release, social bonding, and political expression. Analysis of the music, scenario, choreography, and stage design of Le Bœuf and Les Mariés illuminates that Cocteau and his collaborators incited laughter by drawing on common tropes that resonated with broad audiences, and through staging inside jokes based on real-life instances of music making.
