Architecture éphémère

Architecture éphémère is a fixed-media work aiming to create an immersive experience, allowing the listeners to become lost in the time and space created by the music. The title refers to the idea that through spatial music, it is possible to create an ephemeral, constantly evolving architecture that overlaps the physical environment.

The piece explores the tension between opposite spatial sensations — such as proximity and distance, intimacy and immensity— and the sonic depth of field. Most of the materials are created using synthesis to fill the concert hall with sound shapes of different sizes and characteristics. Moving through distinct atmospheres, Architecture éphémère shifts from explosive, detailed passages, where trajectories can be pinpointed, to soft, diffuse, hypnotic spaces that verge on disorientation.

Architecture éphémère was initially composed during the workshop series Composing Fixed-media Multichannel Music on a Hybrid Loudspeaker Array led by Pierre Alexandre Tremblay from September 2022 to April 2023 at the Multimedia Room (MMR) of the Centre for Interdisciplinary Research in Music Media and Technology (CIRMMT). The piece was then reworked in 2025.
