Composed in 1988 in Santa Maria for the birth of the composer's son, Ricardo, this piece requires a very high level of technical and musical maturity for its interpretation and also introduces the technique of playing with five mallets. The first theme that is presented in the opening section is developed in several variations throughout the piece and is usually accompanied by a rhythmic, polytonal ostinato. In the final section, two other small motives appear with the same rhythmic, polytonal ostinato: the first in the style of the Bachianas Brasileiras from Brazilian composer Heitor Villa Lobos, and the second is a quote of a melody from the gauchos of Southern Brazil, referring to the birthplace of Ricardo.
