Acousmatic Lectures

Errant Sound
an ongoing lecture series

The Acousmatic Lectures have roots in discursive practices and propose a listening experience based on the Pythagorean acousmatic model: a mode of presentation in which the speaker is hidden from the public. Acousmatic Lectures encourage both orator and listener to focus exclusively on the acoustic space that provides a frame for the spoken word, its temperament and tone, without the addition of visual information or the speaker’s body language. For this series of lectures, all visual clues generated by the speaker’s facial and bodily expressions (which normally influence how information is received) remain hidden. Nevertheless, the speaker’s voice and its dissemination in the surrounding environment still convey the speaker’s physical presence. This approach underscores the dialectical conflict between abstract and sensorial information, confronting us with an array of decisions specific to the act of listening itself.

Acousmatic Lectures –view–

The term references a Pythagorean tradition according to which only Pythagoras’s most devoted students were allowed to see and visually perceive him during his lectures. By contrast, newcomers were made to sit before a curtain concealing the master’s physiognomy. Students were therefore left without any visual information and had to try to follow the lectures solely by attentive listening.

The lectures are academic in nature—a deliberate choice of the artist. The speakers are academics and scholars who talk about their specific areas of expertise. The intention is to observe what impacts the acousmatic settings have on participants, and specifically without the influence of any artistic or aesthetic sensory effects. In the Acousmatic Lectures held thus far, a performative character has been observed that condenses the classic academic lecture scenario into an acoustic experience that functions both informatively—on a linguistic level—as well as in an acoustically qualitative way—on the level of the voice as instrument—and is capable of transforming situations, content, and space. These aspects are made legible through the ways in which the acoustic characteristics of the voice interact with the surrounding space. As such, they might be experienced as a means for determining the interaction between and transfer of linguistic and affective sensory information.

What does a line think?

Statements – exhibition view Manière Noire, Mario Asef © 2015

Language is not a welcoming land, as much as we tend to forget about it in daily communication. Reality is also not a welcoming machinery, though it seems that we have grown used to its rusty hinges. Mario Asef’s work detains both language and reality (the cultural engine that produces it) with a minimal intervention that modifies their landscape. He respects the structural elements of language or cultural situations, he studies them. And then he introduces a slight modification that provokes a twist, a bristle that detains some elements of our cultural structure in an unexpected angle. Finally, he puts them back to roll into the structure, now affected and changed, and, most of all, exposed to our perception. The ground of facts is a spiderweb (Der Boden der Tatsachen ist ein Spinnennetz), we read in one of his statements, which could easily be understood under the logic of the aphorism. Common sense is a fragile territory, and our security cannot be anymore established in the ground of facts. Language also abandons part of its power here, and there is rarely a statement in Mario Asef’s work that is not slightly touched, brought back from its bombastic character into a natural move. This is also a general trait of his work. Again, something is modified, and our perception and thought are affected, but this is done elegantly. A scarce or apparently casual line drawn there where you would not need it or expect it, can be enough sometimes. In Asef’s pieces danger is not in tragic and dramatic exposures. It lies right before us, in a very small margin that has been taken out or changed.

A thesis is a Japanese Garden (Eine These ist ein japanischer Garden) says the writing on the opposite wall. It would actually be a relief to think that we can bring our walk through the garden to a memorable ending, the hill that offers us the harmonious view of our thoughts and actions. And we might need indeed a breath into this fragile (or solid sometimes) phantasy before going down back to the garden. This closeness and return to the material is a recurrent question in Asef’s work. Be it a brick, a cake, debris, a lottery poster or the ink of words on the page, the materiality of thought is always perceived. Thus, there is never a two-dimensional experience, space, even in a small caress of volume is present. And this is especially striking in his statements, where language thinks (as it happens with the aphorism) within a very small margin of space and through very few elements. But the weight of the word on the white page (which could turn this kind of writing into visual poetry or slogans) is too much, it unbalances sensitivity. And there is where the line appears. It is never a decoration, and its relation to the words is not clearly stated. But it seems to have the function of bringing back language a little closer to its materiality, even to remind this inked decisions that there is a void around them. Casual, programatic, or even ironic or playful sometimes, the lines that appear in Asef’s work create a relational tension that incorporates language but also goes beyond it. Those lines need to be handled with care, and cannot always be trusted. So the best thing we can do is to approach the ear, the eye, and ask them what are they thinking in there. For there will be no better clue to understand and enjoy the unbalanced garden they are part of.

 The Author

Ernesto Estrella Cózar is an educator, poet, and musician born in Granada who  has lived in New York between 2000-2012. He completed his Ph.D. at Columbia University, and between 2007 and 2011 he was assistant professor of Contemporary Poetry at Yale University’s Spanish and Portuguese department. Since the spring of 2012 he has turned to Berlin as a second base for his artistic and academic work. As a musician, he concentrates on the voice’s potential to explore the poetic process through sound. In this vein, he has created a wide array of performances that have been presented at international festivals in Argentina, Uruguay, Austria, Germany, Spain, Croatia, Russia, Finland, Latvia and the U.S.  Since his arrival to Berlin, he has been teaching seminars at Potsdam University. Moreover, in 2014 he launched The Voice Observatory, along with sound and conceptual artists Mario Asef and Brandon LaBelle. Funded by Berlin’s Senate, this laboratory of investigation offers regular seminars, workshops and performances related to the voice in its acoustic, communicative, performative, and socio-political dimensions. Most recently, his work in cultural management and civic education has led to the creation of the Nomadic School of the Senses.

Urban space and its appropriation by the people who use it is the source of Mario Asef’s artistic work. In his videos, photographs, sound installations, and interventions the artist deals with architectonic as well as socio-political discourse and investigates how they are represented spatially. Like a researcher he examines the constructions of public life by working against the dominant order in subtle ways. This occurs by reordering things without notice or by removing elements specific to the location and adapting them to the art context. Accordingly, these urban objects are first apprehended as artworks when they are documented in photographs or written about in texts.

Asef’s group of works Empirien (1998-2006) presents an entire series of interventions documented in this way. For instance, in the work Fragile—handle with care/appropriation (2004), the artist placed cardboard boxes in front of the Covent Garden Theater Museum in London, which were then taken over by individuals and used as sleeping spots. By converting packaging into housing, Asef indirectly draws attention to the negative spaces of the city, which make life (survival) possible, but also to the present absence of the homeless. Like illegal immigrants or street musicians, the homeless also count among the—for the most part—undesirable users of public space.1 The artist stages this situation like an experiment. That vagrants then make use of it in practical ways undermines the efforts of local authorities.

In and of themselves the unforeseen and the ephemeral are inherent to Mario Asef’s interventions. He never knows how long his rearrangements will last or whether or how passersby will take them over and put them to use. This participation is the trigger for a non-verbal communication outside of cultural institutions. For the most part the users of the locations involved quickly grasp the initiative, deconstruct the intervention, and reestablish the usual “normal order” of things.

Raumprothesen (spatial prosthetics) can be viewed in many respects as a further development of this creative process. In this case, urban phenomena are actually translocated into the art establishment. Here Asef manifests his socio-critical stance by inviting street musicians to play at his opening. The performative evening was consciously designed to provoke interaction between the art-going public and individuals who operate primarily within the urban locations outside of cultural institutions.

In contrast to Empirien, the participation of everyone involved takes place within the exhibition space. As a result of this appropriation beer bottles, cigarette butts, and trash pile up on the floor and imprints from fingers and people sitting are pressed into the sculptural elements—the “Raumprothesen”—that the artist has integrated into the exhibition. “Prothese” (prosthetics) means here, so to speak, the artificial extension of the room that fulfills a specific function. As such the objects don’t even stand out at first. Rather, their white color and inconspicuous positioning on the margins allows them to be seen as a fixed component of the exhibition space.

A central aspect of this work involves returning the purported sculptures to the public locations where the elements that inspired them formally are found. For his work Asef initially pilfers material from the city. In this case polystyrene insulation board for acoustically isolating homes is used. In the context of his exhibition this building material is transformed into sculptures. Through their use (disintegration), mostly by the musicians to whom the sculptural elements were assigned as stages, they are, in turn, viewed as everyday objects. Throughout the entire duration of the show the viewer can observe the process of using the space along with its Prothesen. In addition the brief musical performances have been captured in a documentary video as staged memory, and are continuously on view. Here the quality of the recording plays a secondary role. Asef films more like an anthropologist who attempts to understand the circumstances from a distance. After the presentation in the art context is over, the objects and musicians alike make their way back onto the streets. Once there, people will again use the “Raumprothesen” as seating and eventually dispose of them. With this, a cycle of varying translocations and ascribing of meanings apparently comes to its end.

Whether in urban public space or within the space of an exhibition, the experience of those involved in Mario Asef’s interventions go far beyond the actual participation. Rather, through his subtle interventions, the viewer is sensitized to the processes at work in urban, social surroundings.

1 Asef’s socio-critical stance goes back to the artist’s own personal experiences. He himself migrated from Argentina to Germany twelve years ago.

Shifting the Focus

The opening of Mario Asef’s exhibition Raumprothesen für frei zusammenwachsende Sozialorganismen (Spatial Prosthetics for Freely Integrated Social Organisms) at arttransponder was a big celebration. As announced on posters in the exhibition space, various Berlin-based street musicians, invited by the artist, played one after the other. The musicians hailed from northwest Africa, Turkey, and Russia, and also included a World Music DJ from Argentina. Toward the end of the night the musicians spontaneously improvised together. For viewers the gallery visit became a musical journey through world cultures whose sounds and voices became increasingly mixed over the course of the evening. At first the musical event seemed to be the focus here, however, during the remainder of the exhibition the essential conditions and multi-layered referential structures of the project became evident.

The “Raumprothesen,” which give the exhibition its name, served as individual stages for the musicians. Made out of insulation board, the abstract geometrical shapes in the form of ledges and steps inconspicuously extended the stark architecture of the White Cube into the space. While the artist-designed objects that add to the existing architecture are certainly a focus of the exhibition, their designing points more significantly to a symbolic shifting of the categorization-defying architectonic remains—which Mario Asef groups under the neologism “Raumprothesen”—from the realm of urban public space to the (institutional) art context. In the sense of the dualism of Site (here: public space) and Nonsite (here: gallery room), once formulated by Robert Smithson, a kind of displacement also occurs here that changes our perceptions. Both of Smithson’s terms also explicitly refer to their respective phonetic equivalents of Sight and Nonsight: what consciously enters our field of vision first affects us and holds our attention. Shifting the Raumprothesen from urban space to the gallery space leads therefore not only to a revaluation of these elements, which are completely neglected—if not repressed—by city planners and architects, but generates literally and figuratively a platform for street musicians. In one’s perception of public space, illegal immigrants are—like some of the participating musicians—often degraded to objects that seemingly belong to the cityscape. Shifting the location of the musicians also signifies for them, in analogy to the Raumprothesen, a revaluation of their musical playing and their recognition as subjects of our society. If insulation board typically functions to isolate rooms acoustically, the voices of immigrants are now the focus of attention on top of them.

This new form of public appearance didn’t seem to put all of the invited guests at ease; the fact that the Romanian musicians didn’t even show up for the opening night might be an indication of the explosiveness that goes along with this shift. The White Cube as an exclusive space closed off from the outside world becomes itself a far more open platform here; the borders between the experience of art and the urban everyday are permeable. Thus everything that transpires in the exhibition space also always points to its external reality. At the same time remnants from the opening night, such as scattered beer bottles or candy wrappers, become a part of the work as much as they are an index of a prior and potentially missed event. These can be appreciated during the concert-free period with a video from the opening celebration that plays on a small monitor in a corner of the room. Via this shift in medium a direct relationship is made to the video work Violinparis (2007)—presented at the same time in the exhibition—whose symbolism forms the point of departure and the basis of the questions being addressed here: with very little concern for technical effects and no subsequent editing, Violinparis presents the portrait of a Parisian street musician who plays her Turkish Rebec undisturbed and uninterrupted in front of the Centre Georges Pompidou while museum workers busily measure the square around her without paying her any attention. Over the years she has, as a matter of course, become a fixed element of the square, the sound of her instrument has become the constant soundtrack to local events. If, at best, she makes waiting in line for the Centre Georges Pompidou easier to deal with as a result of her playing, then in an exhibition context she is granted a presence and recognition that she hardly ever benefits from in everyday life—even if, or precisely because, a surprising number of visitors remember her from their visits to Paris.

In a final action at the end of the exhibition, Mario Asef converts the here-mentioned shifts into a circular flow, thus turning the previously ideal repercussion of this project on external space into a material. As an art object, but mainly as prototypes of architectonic blank spaces, he places the slowly disintegrating insulation board-constructions in central locations around Berlin such as Potsdamer Platz, Alexanderplatz, and Mauerpark, reintegrating them (back) into urban space. They become a part of skateboard ramps, incorporated into graffiti, or used for seating. Now it’s only a question of time how long the impermanent material can hold its own ground.

Via this intermingling of two distinct spaces, each with their own inherent social customs and unspoken rules, Mario Asef’s exhibition project Raumprothesen für frei zusammenwachsende Sozialorganismen ultimately becomes itself a test case for urban development. A test case that demands a new way of looking at our architectonic surroundings and social interactions—both in the urban environment as well as the exhibition space.
