Music & Sound Installations:

  • Live-Performing “Leiyla and the Poet (1959) - Halim El-Dabh”

    16.2.2024 – Mizizi Ensemble performance at The Mist, Nairobi (KE) featuring the music of Halim El-Dabh, as well as their own compositions and improvisations. Performers: Nyokabi Kariũki, Monrhea Carter, Bernt I. Waærstad, Kostia Rapoport, Tim Grund, Labdi Ommes, and Alex Hofmann

    In the second research cycle of the FWF-PEEK project “Études for live-Electronics” (AR 743) we chose to work with an electronic composition in the format of tape music, called “Leiyla and the Poet” (1959) by Halim El-Dabh. “Leiyla and the Poet” was performed by the Mizizi Ensemble as a site-specific performance for the renowned underground venue, The Mist.



  • Live-Performing “Stria (1977) - John Chowning”

    29.6.2023 as Lecture-Recital at Orpheus Instituut, Ghent, BE.

    19.7.2023 Performance of ‘Stria’ by John Chowning as a live-electronics duo performance by Dustin Zorn & Alex Hofmann, Akademie der Künste Berlin, DE.

    As a case study within the FWF-PEEK project “Études for live-Electronics” (AR 743), the composition ‚Stria‘ by John Chowning (1977), was performed live, using a shared interface setup that is split up between two interpreters who control the sound synthesis. Through the concept of a duo live performance, the effort and the communication that are necessary to re-enact the piece become visible for the audience and each performance becomes a unique interpretation rather than a staging.



  • “Study for virtual keyboard instrument and hand tracking in a VR environment” (2021)

    Interactive Sound Installation // UA: 17.6.2021

    This sound installation explores the non-physicality of virtual environments and their impact on interactions with virtual musical instruments. Using hand-tracking technology, visitors of this virtual reality (VR) sound installation can play a virtual keyboard instrument displayed via a head-mounted display. Following an experimental approach to contemporary piano music, in this installation the entire instrument behaves differently compared to the real world. Due to the virtual-physical system, the expected quickly transforms into the unexpected. The implications of an instrument with free-floating keys that produce sound when they collide are to be explored by the visitors.

  • “Study for Saxophonist Avatar and two Loudspeakers in a VR environment” (2020)

    Interactive Sound Installation // UA: 9.9.2020 - SOUND CAMPUS/Metaverse -> Ars Electronica Festival 2020

    “Study for Saxophonist Avatar and two Loudspeakers in a VR environment” is an artistic research project in progress, that explores Virtual Reality (VR) as a performance space for experimental music. This experiment puts the listener into a scene with stroboscopic lights and dissolving walls of a large and almost empty hangar. A group of listeners can explore the scene that comprises both light effects and sound. The scenery contains a saxophonist avatar, two loudspeakers and a sofa, placed with enough distance for the listeners to move around between the sound radiating objects.

  • “65.4” - 3’30” (2019)

    Half-Physler, Cello und Live-Elektronik Live electronics including digital processing, embedded systems UA: 28.9.2019 - ICSC 2019 Cagli (IT), Alex Hofmann (Halfphysler), Sebastian Schmutzhard (Cello + COSMO Live Electronics)

“65.4” is a drone piece for live-processed Cello and Halfphysler. Inspired by the opening of the music podcast ‘Klangangriff’ by the Georgian artist Yakkushi, Hofmann and Schmutzhard teleport the sound atmosphere onto a live stage using the cello and physical modelling with Csound. The live processing of the Cello is based on effects of the COSMO library and runs on the embedded ultra low-latency platform Bela. The Halfphysler is a hybrid acoustic-virtual single reed instrument that has been presented at NIME 2019 the first time. This novel instrument is comprised of a sensor equipped clarinet reed and a virtual tube, simulated in realtime using Csound and the Bela board.
