From an ethnographic research work with llano workers (cowboys) in cattle ranches and farms, and the implementation process of the Special Safeguarding Plan for Llano Work Songs (PEScU), this arti- cle proposes a reflection on the problems that have involved the fragmentation of the cultural world of this expression. The problems are represented in the way of thinking the songs, loudness, sound objects and knowledge as intangible cultural heritage, and the objects, tools and associated places as tangible cultural heritage. While the PEScU talks about knowing, revitalizing and communicating as safeguarding strategies, its local management has been limited mainly to the dissemination as a music practice. As a result, the tangible universe has been underrated in the implementation of the safeguard. It is concluded that the sound and the tangible, are thought as independent worlds by the cultural institutions and their safeguarding processes, and common points are proposed to comprehend integrally what in practice seems not to need integration, to form a single sociocultural universe.
