| Sumario: | The thesis resolves the geometry of and elicits a model for hyperboloid spindle bells, which allows for the creation of the exterior stop for the large organ carillon in the Sagrada Familia that Gaudi designed for placement in the Nativity façade towers. The stop has been sized to fit a minimum of 84 bells, thereby demonstrating the feasibility of obtaining the lowest notes in a conventional manual. This was a problem that could not be solved with the traditional shape of the bells, leading Gaudi to research and work on his own design for these bells. The results were obtained through extensive research and review of documents, some which were previously unpublished, on the musical design of the Temple developed from a cross disciplinary perspective including projective geometry, algebraic geometry, organology, acoustics and across the history of architecture and musicology. The research also documents and resolves geometry of the only remaining bell from Gaudi's extensive efforts to solve the problem of the carillon, which began with the considerably large cylindrical tubular bells that were invented at the end of the 19th Century as an alternative to the liturgical tower bells. The hyperboloid surface provided in Gaudi's design responds to the needs for setting the geometry parameters for its formation in the workshop. This is in order to optimise its dimensional scaling and enable resolution of each of the notes on the manual. It has also been analysed in the reflective and emissive areas, resulting in the discovery of the surface as an optimal resonance tube, which makes it both suitable and effective as organ façade reeds whose resonance exceeds the conical and even the classical exponential horn. This discovery also resolves the façade reeds and reed stop design of the Passion façade while at the same time providing an ordered distribution of the highs and lows and consonant families in the bells of the Nativity façade. In this way the sound of the higher notes further from the floor are successively amplified by the lower bells, thus bringing its sound, in a certain way, closer to the position of the listeners immediately outside of the Temple and reinforcing the effect of the abat-sons, which Gaudi incrusted in the towers for this purpose. The road taken to determine the geometry of the thickness of the Gaudi models also provided a profiling model of the traditional cup-shaped bell, which, with a normal thickness variation, obtains the main aliquots converted into major-third harmonic and fifth harmonic, thus exceeding the irregular contemporary shapes obtained by calculating the finite elements and techniques of shape optimisation. The path of the work also provides for the discovery of different sources that derive from science dissemination that Gaudi so ingeniously applied to architecture and the techniques and trades that it involves. In the area of geometry, this work also contributes to the knowledge and the adaptation by Gaudi of the projective devices of the period and the techniques that analyse the geometry of these surfaces by ruled generation or torsion in the same way that we can currently analyse the geometry of these surfaces through infographic software. These contributions allow for updating and reinterpreting Gaudi's philosophy. Lastly, the thesis also contributes to the knowledge and analyses, unknown until now, of a new ruled surface discovered by Gaudi and to which he even attributed a constructive application. Gaudi defined the surface obtained as a general hyperboloid, beyond the Scalene hyperboloid (general hyperbolic hyperboloid), which is why I have named this surface Gaudi's supra-hyperboloid. |
