“Mari’s it is a commissioned by the clarinetist and friend António Rosa, to whom I dedicate it. This sonata is divided in three movements. The first one tries to symbolize a “constant fight” between Clarinet and the Piano. The second movement, calmer, represents the exhaustion of the first movement, being the piano the dominant instrument, symbolized by the rhythmic and harmonic ostinato. The third movement begins with solemn introduction which evolves, afterwards, into a rhythmic game created by the constant metric alterations”
