Visualising the Voice of Maria Callas

VR Exhibition – Installation 

Visualising the Voice of Maria Callas


A Greek National Opera (GNO) partnership with the Digital Media Lab (DmLab) of the Technical University of Crete. The event forms part of the Greek National Opera’s tribute programme marking the centennial anniversary of Maria Callas’ birth. It is also part of the 2023 UNESCO Maria Callas Anniversary proposed by the Hellenic Ministry of Culture. The VR exhibition follows an intensive educational workshop that took place between 1-7 December 2023 at the Greek National Opera, Athens, Greece.

 As part of the ongoing collaboration between the Greek National Opera and the Digital Media Lab – Technical University of Crete, a pioneering educational workshop titled Visualising the Voice of Maria Callas was jointly organized by the two institutions. On the occasion of the celebrations marking 100 years since the birth of Maria Callas this workshop focused on further broadening the relationships between architecture and music, space and sound, and –through the use of new digital media– sought to experimentally visualize the very sound of the greatest soprano.

More specifically, the aim of this workshop was to offer participants the opportunity to understand the use of creative new media tools. Participants experimented with the three-dimensional models (3D point clouds) of the scanned interior spaces of the GNO building designed by Renzo Piano that resulted from the preceding research project by DmLab, and sought ways of capturing interactions between the voice of Maria Callas and the spaces of the Greek National Opera. This lead to the creation of virtual installations that, taken as a whole, illuminate this iconic figure from an entirely different perspective. The software used was TouchDesigner by Derivative.

 The first VR exhibition has opened inside the foyer of the Stavros Niarchos Foundation Cultural Center, one of the best contemporary opera houses in Europe, on December 7, 2023, and the second one will open in Chania in Spring 2024.
