Sever Tipei / Illinois Composers’ Forum

October 21st, 2009

Yesterday afternoon, Professor of Music Sever Tipei presented at the Illinois Composers’ Forum on recent projects and research.

Sever offered a demonstration of SoundMaker–an additive sound synthesis engine with a web-based interface–which readers can explore at http://aurel.music.uiuc.edu:81/SoundMakerWeb/Login (requires that users establish a free account).  The program, written in C++, enables composers to generate sounds “from scratch,” which Sever prefers over sampling already-created sounds.

Sever’s method of composition is to combine these sounds (data) with algorithm (programmed rules) to create compositions without further human intervention in the loop.  Artistic “intuition,” Sever says, thus occurs in the sounds created and chosen as data, in the composition programming, and in any adjustments to the programming that occur after its results, its compositions, are heard — never in the altering of the composition so generated itself.

Sever also discussed a course in Musical Informatics that he developed over the Summer with the aid of a small grant.  His goal in the course is to revolutionize the teaching of music theory: to teach through primitive, abstracted concepts rather than higher-order concepts that are associated with particular musical styles and examples.  This new approach to musical theory helps to orient students to composition more independently, so that their sense of what is possible in music is not pre-determined by historical technique and example.  In his teaching as well as in his own practice, Sever is after achieving a truly contemporary aesthetic.  His aesthetic has been most strongly influenced by the theory of John Cage (e.g., Silence, A Year from Monday, M, Empty Words, X, 1961-1982) and Iannis Xenakis (i.e., Formalized Music: Thought and Mathematics in Composition: Pendragon Press, 1992).

Sever’s defines his own contemporary aesthetic as inherently secular, broadly along the lines of a modern, intellectual scientific worldview.  Art, he says, whether one admits it or not, whether one of self-conscious of it or not, always expresses a “worldview.”  This worldview is communicated through the structure of the “parallel reality,” the “imaginary,” the artist creates in his or her work.  This parallel reality reflects the artist’s view of an actual real, which is significant for at least three reasons.

First, it means that mathematics becomes an ideal “tool” for creating a parallel reality, since mathematics is the best tool for studying an actual real.  Mathematics serves as a basis for abstracted musical theory, the kind Sever uses to teach and create composition.

Second, it means that the parallel realities that artists create express an ethics and artists are responsible for the ethics their creations express.

Third, it means that a parallel reality is, like an actual real (what Sever might call “the” actual real), a complex, dynamic system.  In such a complex, dynamic system, Sever believes there is no inherent hierarchy, no inherent destiny.  Yet, there are laws of consequence, “laws of physics,” of action and reaction, that determine how one object or event acts upon another.   In his computer-aided composition, Sever represents this principle as a “template,” or “framework,” of “static symmetry” that runs throughout a “version” (what might more traditionally be called a “piece,” except that Sever intends to designate an ongoing composition over the past 20 years that generates new versions of the whole rather than separate and distinct pieces of original matter).  On “the surface” of such static symmetry, Sever creates one or more layers of “probability,” of “chance,” that follow only “statistical laws of distribution.”  These top layers represent his sense of the probability governing regular occurrence in addition to the “laws of physics.”

The ephemeral nature of such an existence, of sensation and of human life, is captured in Sever’s desire to treat the public performance of each version (of the Manifold as a whole) as a singular event that, after it is done,  is not to be repeated.  Such repetition would reify (and could lead to the commodification of) the piece, turn it into a fetish object, rather than allow it to affect in the moment and be no more.

Ultimately, Sever’s dream is to create a Brewing, in which a composition would be continually created computationally, never ceasing.  The composer might open the lid of the “black box” of the programmed environment to occasionally reveal what is being made and remade along principles of interaction as inexorable as physics and as unpredictable as chance.

eDream Affiliate IUPUI to Co-Host Intermedia Festival

October 20th, 2009

Intermedia Festival will be co-produced by eDream’s affiliate program at IUPUI.  The Festival will be held right in our backyard, too — just 2 hours east, in Indianapolis, this coming Spring, from April 23-25, 2010.

The Festival will focus on “emerging artistic trends in telematic and media arts,” in which telematic art is understood as synthesizing “traditional arts with networked, interactive hypermedia and performance content. The resulting productions connect media-rich spaces using modern communication systems to create powerful and evocative experiences.”

Some participants (from dancers and theorists to scientists, musicians and videographers to technologists) will engage live, while others will participate in exchanges in realtime online, through “multi-site, high fidelity communications technology developed in the Telematic Lab at the Donald Tavel Arts Technology Research Center, Indiana University Purdue University Indianapolis (IUPUI).”  The Indianapolis Marion County Public Library is co-producing the event, which is supported by an Indiana University New Frontiers grant from the Lily foundation.

Stay tuned for further news of eDream’s involvement!

Siebel Scholars at eDream

October 15th, 2009

Two of Guy Garnett’s graduate students have been named Siebel Scholars, Class of 2010: Brett Jones and Rajinder Sodhi.  This major honor was established by the Siebel Foundation “in 2000 to recognize the most talented students at the world’s leading graduate schools of bioengineering, business, and computer science.”  Siebel Scholars  “form an active, lifelong community among an ever-growing group off leaders.”  Each year, just 80 students across the globe are chosen, based on their academic excellence.  Brett and Raj represent the best in Engineering at UIUC, which is ranked with awarded Colleges of Engineering at Johns Hopkins, MIT, Stanford, UC-Berkeley, UC-San Diego, Carnegie Mellon, Harvard, Tsingua (Beijing), and MIT.  We are all very proud of them!

Astral Convertible Blog

October 13th, 2009

On October 2nd, John Toenjes debuted an Astral Convertible blog (see eDream’s Projects page for more details), which will follow his and our collaborators’ progress in pre-production work for the restaging of this contemporary American dance masterpiece.  The blog provides special insight into the complex technical challenges such an arts-technology saturated production faces as well as into the importance and nature of collaboration across disciplines.  To date, the Astral Convertible team has, with John’s lead, nearly completed assembling all of the foundational performance technologies: from networked sensors to a trained machine learning program to tower construction (a physical stage element), with only a circuit left to complete.  What’s more, this work will be completely documented by the end of October.

Here is a taste of Astral Convertible blog’s first entry, written by John Toenjes:

“I and a wonderful team of collaborators at the University of Illinois Urbana-Champaign have been working for over a year now on this project, ‘reimagining’ and ‘restaging’ the dance work Astral Convertible, by choreographer Trisha Brown…Today’s post concerns yesterdays work, which was done at the wonderful Digital Performance Laboratory at NCSA. At noon, Mary Petrowicz and I met to view the video of the run-through of the dance, which was held in the Krannert Dance Rehearsal room on Friday Sept. 18. The aims of this session were to

  1. Identity both qualities of movement, and specific gestures in the dance, that would lend themselves to the machine learning algorithms Mary has developed for use in the performance,
  2. Identify group dynamics and behaviors that could also work in her machine learning system,
  3. Determine the best location for a second sensor attached to the dancers’ bodies.
We identified a list, and next rehearsal we will hopefully get some dancers to wear the sensors and try to train the computer to recognize the qualities and gestures. In the meantime, Mary will be working on updating and extending her machine learning models to incorporate these new observations.”

Therese Tierney

October 13th, 2009

We eDreamers were delighted to meet so many interesting and talented colleagues at the recent Illinois Informatics Institute’s Open House. Among them was Therese Tierney, a professor who has just joined the School of Architecture and whose work and interests readily evoke the brave new arts-technology space in which we work. As an example of her interests, Therese cited Murmur, an archival audio / documentary oral history project that has so far taken place in a number of cities / locations in Canada, the US, and Europe.

What captures Murmur’s orientation for me is this portion of its project statement: “It’s history from the ground up, told by the voices that are often overlooked when the stories of cities are told. We know about the skyscrapers, sports stadiums and landmarks, but [murmur] looks for the intimate, neighbourhood-level voices that tell the day-to-day stories that make up a city. The smallest, greyest or most nondescript building can be transformed by the stories that live in it. Once heard, these stories can change the way people think about that place and the city at large.”  Evoked here is a sense of space caught up in time–shot through with impressions of life undergoing swift transition, yet also meaningful change (i.e. story)–somehow preserved in the “heard moment,” even as some digital techs hope to capture the ephemera of a web community or an urban painter a day at the park or marketplace.  To make a still more figurative leap of analogy, I am led to think the effort of psychics to gather “sense impressions” of place–a whispered word or snatch of song, even as Murmur seeks to name and fix our urban ghosts through the sounds of their passing.

Therese’s own interests are even more strongly expressed through her publications.  She’s the author of Abstract Space: Beneath the Media Surface (Routledge, 2007), which, according to editorial copy, “engages discourses from architecture, visual and cultural studies to computer science and communications technology to present an in-depth multi-media case study. Tracing a provisional history of the topic, the book also lends a provocative and multivalent understanding to the complex relations affecting the architectural image today.”  Along with Anthony Burke, Therese also edited Network Practices (Princeton Architectural Press, 2007), in which the essays, again according to editorial copy, “capture this unique moment in the evolution of design, where crossing disciplines, spatial interactions, and design practices are all poised to be reimagined. With contributions by architects, artists, computer programmers, and theorists and texts by Reinhold Martin, Dagmar Richter, Michael Speaks, and others, Network Practices offers an interdisciplinary analysis of how art, science, and architecture are responding to rapidly changing mobile, wireless, and information-embedded environments.”  Therese has also published articles in Architectural Design and our affiliate Leonardo.

Needless to say, we’re thrilled to find Therese has joined us on campus, and are looking forward to learning from one another and working together!
