T. S. Eliot has interest in the popular culture genres such as dance music, minstrel show, ragtime jazz, Tin Pan Alley songs, vaudeville, burlesque and slapstick as well as in the classical genres. He employs the elements of popular culture, including minstrelsy techniques and jazz rhythm so that religious themes can be fused in his early poems and secular plays. However, only a few critics have intensively written on this aspect and the subject of jazz and its relation to Eliot's works deserve more attention. This study aims to analyze T. S. Eliot's early poems and Sweeney Agonistes by discovering the elements of jazz rhythm which play an important role in the works both as a poetic device and a sound value with religious and cultural connotations. Eliot took an experimental step towards reviving human natural rhythm in the poems by using jazz elements inherent in the primitive music in order to show the shallowness of civilization. For him such a revival was a matter of great cultural significance. In fact, they are devices not only to explain his cultural ideas but also to illuminate the rhythmic pattern of his poems and plays. He makes symbolic use of jazz elements in his early poems and Sweeney Agonistes, which itself as a genre may provide only the cheapest entertainment and are seemingly empty of any serious purpose. However, in fact, he did not employ them merely to entertain his audience, but managed to convey significant cultural meaning through them.
