This dissertation is comprised of two musical works that set the poetry of Matthea Harvey. These songs explore themes of terror, contingency, complacency, and the grotesque. The first musical work presented here is "as if to hold the hemispheres of their own heads together (black; dahlia 1)" for flute, oboe, tenor saxophone, soprano, violin, violoncello, and double bass. This piece sets Harvey's "How We Learned to Hold Hands, " from the poet's collection Modern Life. Ensemble Dal Niente premiered "as if to hold the hemispheres of their own heads together (black; dahlia 1)" in January, 2014. The second musical work presented here is "the future of terror, " for flute and soprano. This song cycle sets Harvey's series "The Future of Terror, " also from her collection Modern Life. Liz Pearse and Élise Roy — for whom this work was written — premiered "the future of terror" in May, 2014.
