Resumen
The present article aims to propose a method for composing polyrhythms using mathematics. To achieve this, we employ box notation and duration patterns to construct a rhythmic pattern with an accented pulse. This accented pulse, called the "axis pulse," moves along each position of the durational pattern notation, allowing us to obtain different rhythmic patterns. These patterns are grouped into a matrix, thus representing a polyrhythm. Subsequently, we propose matrix addition and subtraction as a creative resource to generate more polyrhythms. Finally, as a consequence of this composition method, we visually and symbolically represent the polyrhythms. A matrix can be analyzed as a system of linear equations, allowing us to graph it on the Cartesian plane.
