Lucha Reyes and the ensemble Los Morochucos made a name for black performers among the leading interpreters of the vals criollo and marinera genres. The vals criollo derives from the Viennese waltz. The music is not originally Afro-Peruvian, but was converted by phrasing lyrics and playing the vals criollo with slightly off-beat accents. The addition of the cajón to the traditional instrumentation of two guitars served to give the vals an Afro-Peruvian dimension. Marinera songs honor the sailors who fought in the war with Chile and are played with two guitars, a cajón, and accompanied by hand clapping.
