Aura forms part of an ongoing series of works exploring rhythm as a point of departure for the structuration of an entire piece. A metric skeleton based on a numeric sequence of numbers and proportions serves as the primary layer from which the whole organization of the musical material (in terms of pitch, form, density of events, etc.) is derived. Beyond that, the piece describes an expressive curve which is treated in an almost romantic sense, thus presenting a tension between the rational and the emotional forces of the composition.
The title refers to Walter Benjamin's concept of the "aura" of a work of art, and also suggests an idea of the piece being a sort of multilayered map of the thoughts and feelings of a person.
