Purpose: In recent years, the interest in creating new educational spaces has increased substantially, aiming to influence the methods of learning of our students and to adopt new educational strategies. This article highlights the importance of the atmosphere when remodeling musical practices. Methodologically, when transforming a space, we do not only have to improve the physical architectures but also the pedagogical ones, as well as keeping the practices consistent with these changes. The MUSICLAB CR-209 'Sound laboratory' have been built in Valencia (Spain). This is a hybrid space designed especially for collaborative projects -teachers, artists, students and researchers- in which sound is treated as an element or raw material that can be molded and adapted to what each project demands. Methodology: The method used in our research was participatory action research. In order to submit the LAB to judgment, three artistic actions were designed and developed. Results: In this paper, the results showed the main strengths and weaknesses in the design of the space MUSICLAB CR- 209 related to the synergies generated through musical practices: the connections established at an interpersonal level, the methodologies and artistic actions developed, the participation and the coordination between the different participants agents. The weaknesses found are related, not so much related to the space itself, but rather to the lack of experiences such as the one described. In this sense, certain barriers and resistances have had to be overcome by all the actors involved. Implications: In conclusion, we close with a positive vision and we think that this is a novelty experience that stand out for their creativity in the development of contemporary languages and highlight the importance the atmosphere in the educational processes. Our ultimate aim is to provide a proposal that might inspire music and artistic educators when building a new school model more in line with the demands of society s. XXI.
