The composition consists of a long path or trajectory that unfolds through a large subset of the sounds producible by the instrument. The path is made up of many ascents to peaks of intensity, height and density of events and sometimes sweet and sharp descents from which to start with renewed tension. Each typology of sound is present in several sections of the work and, in at least one of these, is specifically developed. The electronics uses the sounds of flute to build live many timbric colours, stratifications and immediate answers to the instrumental gestures. The sounds of wind, which represent the primary energy of the sound of the flute, are widely used in the composition and begin and terminate the piece with intensity to the limits of hearing. The composition "Traiettoria tesa" is dedicated to the flutist Gianni Trovalusci. Short biographical notes.
