B flat Clarinet and Piano. Contrived as duos for Bb clarinet and piano, Preludio No.1 and Preludio No.2 are exemplary of one of the diversified creative tendencies within contemporary Cuban chamber music, demanding the revelation of the varied spectrum of technical and interpretative possibilities of both instrumentalists. These compositions feature the use of polytonality, the simultaneous application of various modes and complex polyrhythmic passages established between the clarinet and the piano; yet, they also show those huge intervallic leaps and the existence of fragments of improvisational or cadence-like character determining the clarinet's melodic discourse.
