Resquício/Síntese is a performance that crosses the methods of sound production and the extension of the technique with corporal expression. The object is improvisation, creative freedom is given to its participants, where there are only 4 key points / movements, which act as the guiding thread. Through the use of the piano with the extension of technique, sound manipulation (recording and real-time reproduction) and the use of the analog synthesizer, textures and soundscapes are recreated, which act as the motor force of the dancing entity. The sound entity of dense spectral character and extremely extensive harmony creates space for the emergence of the melodic lines that guide the entire performance. The sonority is characterized by admittedly classic passages and by influences of jazz third stream. The bodily expression, concretized by contemporary dance, is the breaking point between aesthetic thinking and musical creation. The dancing being represents the exteriorization, the physical and visible part allowing the music not to be just an auditory stimulus. The artistic communication between the two elements is conditioned by the acting of the third active subject in the performance: the moment, the instant, this is the room where the performance happens, the audience, the pre-disposition, no less important is this who drives the moments of improvisation.
