Disputes concerning the origin of the term bambuco persist among scholars in Colombia, as well as controversies regarding the process of notating the traditional bambuco (3/4 or 6/8), when it penetrates the written tradition of popular music. Composers writing popular and salon bambucos increasingly perceived the advantage of notating it in 6/8. This study investigates the traditional bambuco and its assimilation into nineteenth and twentieth-century cultivated tradition, with emphasis on piano pieces by representative Colombian composers of art music. I include specific analyses of Cuatro preguntas (ca. 1890) by Pedro Morales Pino (1863-1926), ChirimÍa y bambuco (1930) by Antonio MarÍa Valencia (1902-1952), Bambuco en si menor by Adolf o MejÍa (1905-1970), El bambuco by Manuel MarÍa Párraga (c. 1826-1895), and Trozos Nos. 6 and 158 (1927-1970) by Guillermo Uribe HolguÍn (1880-1971).
