A saxophone without its vibrating body, loses all the elements of timbral recognition, it becomes little more than a perforated tube. I wanted to explore this "limit" by drawing living material. The air flows freely through the instrument, while the tapped bell creates a resistance that prevents it from dispersing, forcing it to creep into the slots of the keys. The sound comes out from different points of the instrument, creating a spatialization of the sound source. The two microphones point in the direction of the palm keys and the curve of the sax, they amplify the subtle sounds and distribute them respectively in the right and left channel, returning part of the acoustic spatiality.
