Kryptogramma: what is written in secret characters, in code, in encrypted language. Indeed, this work (written for the Percussions de Strasbourg) is constructed from rhythms borrowed from classical masterpieces which are codified in such a way that they become indecipherable. At the beginning of the score, a certain number of simple rhythms are exposed and then, as they develop, a canvas of ascending movements and large fluctuations in density begin to appear. From then on, the work develops through a series of variations (continuous or interspersed) on the relationships of intervals and rhythms arising from the ascending movements.
