In Rupturas for vibraphone and piano, I try to establish entropic relationships between frequencies, rhythm and harmonic structures as if they were part of structures undergoing various kinds of physical-chemical transformations. In this sense, each note is treated as an atomic particle. After a brief introduction where the sonic material is still being investigated, the atoms are condensed into chords (or molecules) that are synchronously arranged and submitted to different kinds of 'forces'. Further procedures of echoing, colliding, super-positioning, expanding and compressing, will delineate the formal aspects of the work. Throughout the entire piece, vibraphone and piano constitute one single meta-instrument of various layers, rather than two different entities. Also, as an important part of most of my works, I use more abstract techniques to dissect elements found in various cultures around the world. For example, the last section of the piece makes use of repetitive structures that can be referred to the fast-pacing music genre coming from the Northeast of Brazil known as Frevo".
