The title Trajektorie has several meanings: In mathematics it is the graphic solution of a differential equation, in physics it is the path of an object, in social science it is a social development curve. Thus it always describes a process whereby something is changing. Dinescu assigned this term to her composition, because “on the one hand extensive correspondences emerge as well as constant changes to the goal-orientated musical substance, and on the other static structure-types appear, melodic contours which circle around one another and suggest a feeling of endless lingering.”
