A visit to Brazil resulted in the composition Impressioni brasiliane (Brazilian Impressions). He had intended to write a sequence of five pieces, but by 1928 he had completed only three, and decided to present what he had.
The first piece is a nocturne, "Tropical Night", with fragments of dance rhythms suggested by the sensuous textures. The second piece is a sinister picture of a snake research institute, Instituto Butantan, that Respighi visited in São Paulo, with hints of birdsong (as in Pines of Rome). The final movement is a vigorous and colorful Brazilian dance.
