[CUM5]> THE 5TH-OF-MAY URBAN CORRIDOR IS A STREET THAT MARKS THE BORDER OF THE HISTORIC CENTER OF PUEBLA AND SAN FRANCISCO NEIGHBORHOOD. AN URBAN RENEWAL ORGANIZES THE SPACE AND PROVIDES PEDESTRIAN ELEVATED CROSSWAYS, NEW LIGHTING, ART SCREEN AND AN ICONIC PIECE THAT SIGNALS THE PLACE. THE LANDMARK PIECE IS LOCATED IN A DIVISION TERRACE ON AN EXISTING STREET. THE IDEA IS TO CREATE A TRANSPARENT BARRIER DESIGNED AS AN ABSTRACT ARTIFICIAL VEGETATION STRIP. ITS DESIGN, A SEQUENCE OF CURVED STEEL BEAMS, IS BASED IN A DIAGRAM OBTAINED OF THE GRAPHIC REPRESENTATION OF A CHORD. DIFFERENT FREQUENCIES CORRESPONDING TO D#DIM, ARRANGED AS A GRAPH, REGULATE THE ARC SEQUENCE OF THE SCULPTURE.
