The Ocho pequeñas piezas para piano (Eight short piano pieces) were composed from February 8, 1984, to December 26, 1992, and were premiered by pianist Alicia Correas in 2016. The first one, Preludio (Prelude), characterized by the use of polychords, flows between scintillating, rough and neutral harmonies. The second one, Quintas (Fifths) explores harmonies based on the progression of fifths and their inversions. The third piece is a three-voice fugue which features a diminished mode scale. The fourth is reminiscent of an old train lost in some dream. It begins with a gentle melody with intended harmonic ambiguity hovering upon an obstinato. The train stops somewhere but starts again, moving into darker regions until it reaches its final destination: the abrupt awakening. A Sonatina follows, in which the first theme is rhythmic and features frequent metric changes and the second theme is lyrical and expressive. The short development is based on the second theme. The sixth piece is a moto perpetuo in which the melodic line creates iridescence with an ever-changing harmony. A brief piece titled Homenaje (Homage) follows, capturing the impressionistic atmosphere of Debussy. The final piece, Passacaglia, is a theme with five variations. The theme borrows a non-thematic harmonic sequence from each of the preceding pieces, creating a harmonic kaleidoscope that is then developed in the variations.
