Expansion of the 900 museum | Arch Francesco Arrigoni

Can the harmony of a physical space be calculated? Beauty is a subjective concept but pleasant music is an almost universal and much more intuitive expression. One could therefore try to establish a relationship between melody and architecture as there is an experienced metric relationship between geometry and musical harmony. In fact, if you divide a string into 3 parts (fifth interval), into 4 parts (fourth interval) and subsequent fractions, the vibrations emitted by these sections and by the whole string produce different but consonant sounds.
The modules of the three most significant buildings close to the project area were then analyzed in search of a minimum harmonic common denominator. By dividing the Arengario module into 3, one finds a measure that fits all buildings. Imagining to bring this proportion back into music, a solution is added to the context that visually sounds like a fourth interval, that is, a new, different but consonant note.
The search for continuity of the exhibition itinerary requires a physical connection between the two Arengari. As an initial operational assumption, the existing path in the first Arengario is kept unchanged, which will be complemented by the project through an aerial connection and an underground connection (HYPOTHESIS A) or only with an underground connection (HYPOTHESIS B). Both uses the rhythmic modular element that marks the orderly succession of the new intervention and serves functionally both as a structural reinforcement and to channel the systems. In hypothesis A, this motif is present outside and inside the museum complex, in hypothesis B it is only inside.
