Speculum Musurgica

My new installation Speculum Musurgica had its première a few days ago, August 18 2015, and is exhibited in Antwerp Cathedral till November 22, 2015.

Speculum Musurgica, 2015 - detail

I made this new installation for an exhibition on Petrus Alamire, with as content two seven-voice compositions from Petrus Alamire’s sixteenth century music manuscripts: the motet Memorare Mater Christi of Matthaeus Pipelare, and the anonymous chanson Proch Dolor, an elegy on the death of Emperor Maximilian, performed by Paul Van Nevel and the Huelgas Ensemble.

The heptagonal media installation Speculum Musurgica consists of ingenious mirror structures and sound projections that invite visitors to take a physical walk through the rich polyphonic texture of the music.
In a spatialized setting, each of the seven singers is projected individually, for both sound and vision. In the centre of the installation the multiple auditory layers coalesce into a surround sound. On the other hand a more analytic listening mode is possible by physically approaching one of the performers. For the visual layers I use the technique of cylindrical anamorphosis: a distorted image can be observed in its reconstituted form through reflection in a cylindrical mirror. Observing one single anamorphosis brings the visitor closer to the projected image (and sound) of one individual musical performer and amplifies the analytical listening mode. The multiple use of anamorphosis however forces the visitor to make choices and invites to spatially and physically explore and experience the polyphonic texture of the music. In this multi-layered universe, visitors choose for themselves which individual musical lines to emphasize. They go in search of interesting perspectives – whether auditory, visual or a combination of the two – and create their own individual experience of the polyphonic music performed.

Speculum Musurgica is part of my practice-based PhD in media arts, wherein I focus on the appropriation of cylindrical anamorphosis. Using a media archaeology inspired methodology of short-circuiting past and present, I gauge the affordances of this seemingly obsolete seventeenth century media technology and its significance for how we engage with the techno aesthetics of contemporary society.

To wet your appetite: Belgian television had a newsitem on the exhibition & the Laus Polophoniae music festival – also with Petrus Alamire as theme this year – in which my new installation Speculum Musurgica features prominently:


MULTIPLE voice/vision @ Bach Academie 2014

Concertgebouw Brugge has a tradition of a yearly Bach-festival;  BACH ACADEMIE BRUGGE. My installation MULTIPLE voice/vision is part of this year’s edition, that runs from thursday January 30 till sunday February 2. I decided to limit the audiovisual materials to only the Ricercar a 6 from Johann Sebastian Bach’s  Musikalisches Opfer (BWV 1079), performed by Roel Dieltiens and Ensemble Explorations.

MULTIPLE voice/vision is permanently on display during the mini festival, so don’t miss this opportunity to spatially experience Bach’s Ricercar a 6 between the series of live concerts.

At a previous exhibition of MULTIPLE voice/vision I made a time-lapse recording of people spatially exploring the installation, to give you an idea:

Text from the BACH ACADEMIE BRUGGE brochure (in Dutch)

MULTIPLE voice/vision

De media-installatie MULTIPLE voice/vision van Rudi Knoops nodigt de bezoeker uit tot een fysieke wandeling doorheen het rijke contrapuntische weefsel van Bachs Musikalisches Opfer, uitgevoerd door Roel Dieltiens en Ensemble Explorations. In een ruimtelijke opstelling wordt elke musicus apart geprojecteerd, beeld en klank samen. De spatialisatie van de verschillende klanklagen maakt naast een meer immersieve luisterervaring vanuit het midden van de installatie, waar de verschillende sonore lagen samensmelten tot een surround klank, ook een meer analystische beluistering, dicht bij één van de musici, mogelijk. Voor het visuele luik gebruikt Rudi Knoops de barokke techniek van anamorfose; een vervormde weergave die met behulp van een spiegel in de juiste proporties kan worden waargenomen. Het observeren van een enkele anamorfose brengt de bezoeker dicht bij de projectie van één individuele musicus en versterkt de analytische luisterervaring. Het meervoudig gebruik van anamorfose dwingt de bezoeker echter keuzes te maken en zet aan tot een ruimtelijke exploratie van de polyfone gelaagdheid van Bachs muziek. In een universum van barokke beeld- en klankstructuren legt de kijker/luisteraar zelf accenten op individuele muzikale lijnen, zoekt naar interessante perspectieven – auditief, visueel, of een combinatie van beide – en creëert zo zijn eigen perspectief op de uitgevoerde muziek.

English text from a previous exhibition of MULTIPLE voice/vision:

In Rudi Knoops’ media-installation MULTIPLE voice/vision ingenious mirror structures and sound projections create a tension that encourages the visitor to explore music spatially. The installation invites visitors to take a physical walk through the rich counterpoint texture of Brackx’ Ricercari and Bach’s Musikalisches Opfer. In this universe of baroque and contemporary sound structures, viewer/listeners choose for themselves which individual musical lines to emphasise. They go in search of interesting perspectives – whether auditory, visual or a combination of the two – to create their own perspective on the music performed.

Media Art Histories 2013: RENEW

The highlight of my research and writing in 2013 was my paper for the  MEDIA ART HISTORIES 2013: RENEW conference. The 5th edition of the International Conference on the Histories of Media Art, Science and Technology took place in Riga, Latvia, October 2013. The venue for the conference was in the art nouveau district, at walking distance from the old city centre.

In my paper I specifically discussed cylindrical anamorphosis. I focussed on how it differs from the perspectival type of anamorphosis, and in a layered approach I outlined why it is of a completely different order. My paper was accepted for the Media Archaeology theme, and my session would be chaired by Erkki Huhtamo, also the keynote speaker opening the conference. I really looked forward meeting this renowned media archaeology theorist, of whom I’ve read quite a bit, for example the excellent  Media Archaeology. Approaches, Applications, and Implications that he co-edited with Jussi Parikka. Erkki Huhtamo’s feedback on my presentation was stimulating: he thought it was a very deep and thorough approach of a subject that is often treated in a very shallow and superficial way.

The abstract of my presentation:

Cylindrical anamorphosis: thaumaturgical origins and contemporary workings

In this paper, I will trace the origins of cylindrical anamorphosis and analyse why, also today, it manages to weave its uncanny magic. The relationship between anamorphosis and linear perspective is considered indisputable, although it ranges from anamorphosis being a logical consequence of the rules of linear perspective to anamorphosis being a corruption of these rules. Holbein’s ‘The Ambassadors’ is the archetypical example of perspectival anamorphosis—where the distorted image can be viewed correctly from a particular vantage point. Often, anamorphosis is equated with perspectival anamorphosis, and the group of catoptrical anamorphosis—where the reconstituted image can be seen in the reflection from a cylindrical of conical mirror—is usually mentioned as just another type of perspectival anamorphosis.
I will argue that cylindrical anamorphosis, as one type of catoptrical anamorphosis, is of a completely different order than perspectival anamorphosis for a number of reasons: its ghost-conjuring lineage from artificial magic or thaumaturgy through the phantasmagoria (Niceron 1638; Baltrušaitis 1977; Gunning 2009); its being based, not on linear perspective, but on the transformation of data from one coordinate system to another (Holländer 1984); its double visual order (Stafford 2001; Clark 2007); its adherence to the scopic regime of the baroque (Buci-Glucksmann 1986; Jay 1994).
This layering of meanings might help explain the almost natural integration of cylindrical anamorphosis in a contemporary black box media-environment with multiple projections of moving images, an environment where the phantasmagoria becomes part of a contemporary technoaesthetics (Buck-Morss 1992).

I currently have a PhD fellowship at KU Leuven, Associated Faculty of the Arts. This blog documents my PhD research, where I explore the workings of cylindrical anamorphosis in audiovisual media. My practice based arts research shows an evolution towards installation-based works.
