This thesis offers a brief analysis of the devotional music of India within the musical traditions of Hindustani and Qawwali. Beginning with an investigation into the nature of musical religious devotion, I trace concepts of sound cosmology and ontology in Hinduism and Islam then discuss the function and forms of modern devotional performances. In an effort to demonstrate the status of hybridity in Hindustani music to the global music market, I historically contextualize Hindustani and provide a succinct case study of one of the modern architects of the world music genre, Zakir Hussain.
