Within the close collaboration of an architectural design studio and a studio in musical composition, the students were asked to work in mixed groups of both disciplines to develop both a composition as well as an architectural design project. Starting from the analysis of an existing composition, the groups developed design and composition methodologies that could be utilized for the generation of both sound and geometry. Through the interdisciplinary projects we were able to identify possible relationships between the two fields on the levels of concept, methodology, composition and experience. While this interdisciplinary method of working may be less applicable for real-world projects, the required engagement with the other field and its ways of working and thinking has led to a challenging and fruitful questioning of the student’s own disciplines’ paradigms.
