This chapter will analyze Campos’s poetic prose masterpiece, galáxias, as a break with the visual poem as such and instead a focus on the possibilities of sound. Unlike in the concrete poems of the early phase, space is not the main structuring agent here, but rather sound. Negating the illusion of instant communication that visual ideograms produced, galáxias presents itself as a performance text that unfolds in time, emphasizing sequence and musicality.
