The project is placed on the two axis. The axis of hearing sense and sight. Both of them are intersected in the experience of movement in the space. It is stage on which will take part a audiovisual performance-action. The design has as central axis the attribute of human brain to conceives the point that is found a sound source in the space, from three parameters: pan, delay and pitch. The performance will be given from three members. Each one will take his place on the scene, depending on the instrument that will play. More analytically will take his place according his instrument’s timbre, that it is depend on the three above parameters. The movements will be also in connection with the sound as it changes place the sound source. The music will be in the bigger part improvisational, which means that will be composed instantly in front of the audience. Also what will play the musician, will determine also his movement on the stage. Stage it was drawn as n object in the space, on which will take part the whole action. Aim and bet of planning is the object not only to fulfills the above condition but also to be drawn in such a way that the intervention in the space is in the limit of intervention that would not become end in itself and would not compete what would be supposed it supports, the representation itself.
