Visualising the Voice of Maria Callas


A six-day workshop in Touchdesigner, using point cloud data and virtual reality headsets. The aim of the workshop was to offer the opportunity to the participant artists to understand the use of creative new media tools. The participants experimented with the point cloud data of the scanned interior spaces of the Greek National Opera building designed by Renzo Piano that resulted from the preceding research project by DmLab, and looked into ways of capturing interactions between the voice of Maria Callas and the spaces of the Greek National Opera. The culmination of the workshop resulted in a VR installation exhibition held at the foyer of the Greek National Opera from December 1st to 21st, 2023.

This installation focused on exploring the long-standing relationship between architecture and music through an experimental approach that makes use of virtual reality tools. The ten select participants experimented with sounds drawn from specific opera excerpts performed by Maria Callas to mark the centennial anniversary of her birth.

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.
