The Nigerian musical landscape changed significantly following the advent of Christian missionary activity and British colonial administration in the later nineteenth century. New idioms of musical practice which have evolved as a result of this historical process include a new tradition of religious, Christian, music, urban syncretic popular styles, new operatic forms and European-derived art/ classical music. This article focuses on one of these emerging styles, Nigerian art music, as reflected in the life and works of its most notable pioneer, Fela Sowande. After a brief historical background, the article discusses the circumstances of Sowande's life and the beliefs which shaped his composing career and his compositional style. In discussing elements of style in Sowande's works, it examines the nature of the interaction between African and European elements, a stylistic feature which constantly recurs in his works. The article ends by discussing the need to consolidate the growth of this new idiom by putting in place institutional structures within which it can develop.
