This article argues that Brecht’s unique musicality as a poet led to a rich and rarely paralleled collaboration with musical composers. While the young Brecht sketched out his own music for his early poetry and songs, he soon turned to professional composers as partners. The article focuses on Brecht’s three major musical collaborators, Kurt Weill, Hanns Eisler, and Paul Dessau. In addition to the innovative works that Brecht created with these composers, they also stimulated important theoretical writings that led to new forms of opera, as in Brecht/Weill’s Mahagonny and The Threepenny Opera, or a revolutionary aesthetics of film music, as in Eisler/Adorno’s Composing for the Films, which is strongly influenced by Brecht.

Bertolt Brecht, the most influential playwright of the twentieth century, is unthinkable without music.Many of his poems, as well as his forty-eight completed dramas and roughly fifty dramatic fragments, are connected to music.There is hardly another writer or dramatist of the twentieth century who based his work as clearly and decisively on the complex relationship between music, text, and drama.Brecht worked with some of the most important composers of the twentieth century, in particular Kurt Weill, Hanns Eisler, and Paul Dessau.Although Brecht rejected some of the aesthetic ideas and ideology of Richard Wagner, in his ambition to combine the arts together and to leave a major legacy, he nevertheless in some respects ultimately came to resemble Wagner.The music connected to Brecht‘s texts is performed and passed on in the media throughout the world, from the early recordings made by the young Brecht himself all the way to innumerable versions of his “Ballad of Mack the Knife” created and spread by the globalized music market.
