With projections generated by hyper-dimensional geometric movements that intersect a 3D hyperplane, this study addresses how unfixed and coeval interrelationships develop sonic-topographies, and activate harmonic and timbral spaces while undergoing hyper-dimensional transformations.
By visualizing specified timbral content in relation to harmonic movements within such hyper-dimensional spaces, this research puts the interrelationships of symmetry and self-similarity in motion beyond three dimensions in order to make harmonic networks, which would otherwise remain not seen, visible. Offering an approach to re-thinking how discrete mappings of a given tuning can be re-imagined within continuous and inter-dimensional terms, this research also engages with hyper-geometry to unpack expanded possibilities for simultaneity.
In relation to the research addressing specific architectural spaces, this approach to hyper-geometry is intended to give ways for thinking about space beyond enclosure as well as how modes of design can fade into being traces of themselves in between corporeal reach and architecture, ceasing to exist as points of origin.

Re-imagining what lies beyond documentation, this study is conceived in relation to a 3D acoustic model that I designed based on architectural structures no longer standing — namely the 6th-century Basilica of St. John in Ephesus and the Church of the Holy Apostles in Constantinople. Not intended for simulation or a fixed point of observation, this approach to 3D modeling is activated to develop sonic-temporal architecture emerging from two spaces as a way to visualize and re-imagine what lies in-between, through which embodied spaces of the pasts that are erased as well as the presents replacing them become simultaneously visible through the corporeal reach.

Coupled with "Thousand Dead Bodies..." (2020), a work written for three simultaneous chamber ensembles, this research sought ways to approach space as an interfacing medium without using electronics, through which sound and space communicate with each other to generate continually transforming illusionary spatial perspectives. By examining the concert hall acoustics of the WDR Sendesaal, this research also explored modes of subjectivity in relation to space, considering how a sonic event or a spatial sound practice can alter private auditory experiences created by concert hall acoustics within a collective listening experience.
