In this paper we examine the meaning of “folkloric objectivity” (and, thus, of direct folklore and diluted folklore), an expression coined by Brazilian composer César Guerra-Peixe (1914-1993) between the 1950s and 1970s. Attempting to detect the presence of folklore in his compositions for the classic guitar, we also consider the genesis of the works Sonata for Guitar (1969), and Characteristic Duet for Violin and Guitar (1970).
