I’m a musician and an economist. Sometimes you will find me playing acoustic folk rock and blues on guitar, harmonica and voice. And at other times I will be at work, where I apply my expertise in game theory to the computer modeling of social phenomena. I create simulations of people interacting – such as how people decide which way to vote on an issue such as a tax levy, or how people learn to sort objects given to them in an experiment. In these simulations, the user can set up characteristics of the environment, such as the number of people and their individual goals. After things are set up, users watch these interactions unfold. The simulation is a little story, and one need only tweak the inputs to see how the story changes.

As a musician, I was curious if a program that generates social stories could be refashioned to generate musical pieces. I wanted to build a music-generation engine that the listener could tweak in order to get a different piece each time. But not just any tune – a piece with some flow, some story. I like that tension between randomness and structure. On one hand, I want every song to vary in unpredictable ways; on the other hand, I want to create music and not structureless noise.

I created a basic story of predators and prey, whimsically naming the prey “Peters,” represented by rabbits, and the predators “Wolves.” My simulation depicts a plain in the savannah with a green oasis. The prey seek the oasis and the predators seek the prey. Each character has its own goals and the closer they are to achieving them, the happier they are. Both predators and prey want to have stomachs full of food, so naturally they want to be close to their target (be it prey or oasis). As they travel through the savannah, they learn what choices (directions of movement) make them happier, and use this experience to guide them.

So how does this story become music? To this question there are two answers: a technical one and an intuitive one. The intuitive answer is that in real life the story of predators and prey plays out geographically on the savannah, but musically this is a story that plays out over a sonic landscape. To elaborate, I abstracted the movement of the prey and predator on the geography of the plain into the musical geometry of a sonic landscape. The farther north an agent travels, the higher the pitch. And, the farther east an agent travels the longer the duration. In other words, as an agent travels to the northwest, she makes longer-lasting tones that are higher pitched. I also mapped happiness to volume, so that happy agents make louder tones. Finally, so that each agent would have a distinct voice as they traveled through this space, I chose different instruments for each agent.

In the video below I assigned the “church organ” sound to prey, and the “brass section” sound to predators.

Ultimately, there are some things that I like about this piece and others that I do not.

As a harmonica player, I improvise by creating and resolving tension. I think this piece does that well. The predator will pursue the prey into a quiet, low-pitch corner, creating a distant, rumbling sound – only to watch prey escape to the densely polyphonic northwest corner. There is an ebb and flow to this chase that I recognize from blues harmonica solos. In contrast to my experience as a harmonica player, however, I have found that some of the most compelling parts of the dynamics come from the layering of notes. The addition of notes yields a rich sonic texture, much like adding notes to a chord on an organ.

Unfortunately, for largely technical reasons, there is a lack of coherent rhythm and pacing. The programming platform (agent-based modeling software called NetLogo) is not designed to have the interface proceed in real-time. Basically, the overall speed of the piece can change as the processing load increases or decreases. I found that as agents learnt more about their surroundings (and more system resources are allocated to this “memory”), they became slower and slower. To fix this, I capped the size of their memory banks so that they would forget their oldest memories. The closest I have come to a rhythmic structure is by ordering the way that the agents play. This technique makes the piece have a call-and-response feel. If only the piece to had a coherent rhythm,  then I could imagine playing harmonica along with it.

One last comment on pitch: while an earlier version of this piece mapped each step in space to a semitone, things sounded too mechanical. Even though this was the easiest and most intuitive decision from a technical standpoint, it was aesthetically lacking, so I have now integrated traditional musical scales. The minor scale, in my opinion, is the most interesting as it makes the predator/prey dynamic sound appropriately foreboding.

You can play this piece yourself. Simply go to this link with Java enabled in your browser (recommended: Google Chrome). Pressing “Setup” then “Go” will create your own run of the piece. As it is running, you can adjust the slider above the graphic window to change the speed. Press “Go” again to stop the model, adjust any parameters you wish and press “Setup” and “Go” again to see how the piece changes. Here are some parameters to try: instA and instB to change the instruments associated with prey and predators; PlayEveryXSteps to change the pace of the piece (higher results in a slower paced piece); Num-PackAs and Num-PackBs changes the number of prey and predators; the vertical PeterVol and WolfVol adjust the overall volume of prey and predators.

In regards to my version of “Peter and the Wolf,” I have a number of things that I’m curious about.

First, how does this relate to what you think of as music? Do you like listening to it? Which elements do you like and which do you dislike? For example, what do you think about about the tension and rhythm – do you agree the first works and that the second could be improved? Would you listen to this for enjoyments’ sake, and what would it take for this to be more than a novelty? What do you think about the narrative that drives the piece? I chose the predator and prey narrative, admittedly, on a whim. Do you think there might be some other narrative or agent specific goals that might better drive this piece? Is there any metaphor that might better describe this piece? As a listener do you enjoy the experience of being able to customize and configure the piece? What would you like to have control over that is missing here? Would you like more interaction with the piece or less interaction?

Finally, and perhaps most importantly, what do you think of the premise? Can simple electronic agents (albeit ones which interact socially) aspire to create music? Is there something promising in this act of simulation? Is music-making necessarily a human activity and is this kind of work destined to be artificial and uncanny?

Thanks for listening. I look forward to your thoughts.

Norman Corwin: Radio at the Intersection of Art and Commerce

Editor’s Note: Today, Shawn VanCour continues our summer series “Tune In to the Past,” which explores the life and legacy of radio broadcaster Norman Lewis Corwin, the “poet laureate of radio” who died last summer at the age of 101.   Sounding Out!‘s three-part exploration of his legacy by radio scholars Neil Verma (June), VanCour (July), and Alex Russo (August) not only gives Corwin’s work new life (and critique), but also speaks to the growing vitality of radio studies itself. And now, a word from our sponsor, Shawn VanCour.–JSA

An experiment in radio is something nobody ever tries except strange people with a funny look. Good businessmen know better than to try experiments . . . . on account of you can’t play too safe when it comes to trying out new things.

–Unaired passage from script for “Radio Primer,” Twenty-Six by Corwin, May 4, 1941

The story of Norman Corwin is by now a familiar one: joining such illustrious figures as Irving Reis, William Robson, and Orson Welles, Corwin led a new generation of sound artists in developing pioneering techniques of radio drama that exploited the medium’s potential as a “theater of the mind” and inaugurated the celebrated “Golden Age” of network broadcasting. In death as in life, Corwin has been much praised for these contributions, and for his signature style so eloquently analyzed by Neil Verma in the opening volley of this SO! series.

Advertising dollars spent on network radio programming from 1935-1948, based on data compiled in the 2002 edition of Christopher Sterling and John Kittross’s Stay Tuned: A History of American Broadcasting. Advertiser investment climbed sharply, spurred by a corresponding growth in network affiliates.

However, as Erik Barnouw notes in his preface to LeRoy Bannerman’s biography of this broadcasting legend, Corwin’s story is also bound up with a larger economic history of radio, unfolding during a period of intensified growth in and controversy surrounding commercial broadcasting. From Corwin’s first show for CBS in 1938 to his last network broadcast in 1947, the percentage of affiliated stations in the country grew from 52 to 97, while investment by commercial advertisers more than doubled. To answer critics of commercialism and give its network signs of distinction, CBS dramatically increased its public service commitments (what David Goodman refers to as “radio’s civic ambition”), investing heavily in “sustaining” (unsponsored) shows that gave producers like Corwin room for unprecedented aesthetic experimentation.

This second, institutional dimension of Corwin’s story warrants further consideration. Observing the Marxist adage that history is made by individuals not in conditions of their own making, I propose that assessing Corwin’s legacy for radio and sound studies demands we attend not only to the what of that legacy–the techniques Corwin pioneered and programs he produced–but also to its how and why: the institutional context that spawned and encouraged these aesthetic innovations. How, in other words, did commercial concerns at the structural level shape and enable the rise of the “Corwinesque” as a viable mode of sonic expression? What peculiar set of economic relations undergirded these grand experiments in twentieth century sound art, and what lessons might this period offer for understanding creativity and aesthetic innovation in subsequent eras such as our own?

Sounds of Commerce

Corwin’s 1941 play, “A Soliloquy to Balance the Budget,” opened with the sounds of an adding machine and voice of a “soliloquist” tabulating the cost of each musical note and on-air gag. Such is the secret soundtrack of every broadcast since commercial radio’s inception, as one of the past century’s largest and most successful industries dedicated to the business of packaging and selling sounds for corporate profit.

Excerpt from script for “A Soliloquy to Balance the Budget,” broadcast on CBS’s Twenty-Six by Corwin series, June 15, 1941.

Rather than seeing the flowering of the Corwinesque as a brief but “golden” reprieve from an otherwise dark history of commercial mediocrity, I propose we use the case of Corwin to critically interrogate presumed antipathies between opposing forces of art and commerce in U.S. broadcasting, and seemingly intractable tensions between competing goals of public service and corporate profit. Might we see in Corwin, instead, an instance where concerns with profit margins in fact facilitated aesthetic innovation, and where goals of public service and commercial success entered into strategic (if temporary) alignment?

This perspective is by no means intended as a neoliberal apologia for the commercial system. Yet, at the same time, the modes of aesthetic experimentation in which Corwin engaged were never so antithetical to run-of-the-mill commercial forms as traditional histories have implied. Corwin contributed to both sustaining and commercial programs, and the techniques he developed were eagerly copied by radio ad-writers. Moreover, public service programming for CBS was no mere loss leader, but rather offered opportunities for financial profit both in its own right and as part of a larger system of coordinated transmedia flows. Listening for the sounds of commerce in these programs demands  a more sophisticated grasp of industry economics than the reductive binaries of traditional histories allow, beginning with an interrogation of the Romantic ideology of art on which those binaries rest.

De-Romanticizing Radio Art

Unlike other radio greats such as Robson and Welles who worked extensively on commercial series, what distinguishes Corwin in traditional accounts is his alignment with a protected sphere of noncommercial programming. Hired by CBS to work on sustaining series such as the Columbia Workshop, Corwin was celebrated by contemporaries like Richard Goggin as “pleasantly isolated from ‘commercial’ broadcasting,” with its “struggle for sales and maximum audiences” (63-4). His official biographer similarly praised him as an artist who “flourish[ed] in a freedom of ‘sustaining’ programming [that was] the hallmark of the Golden Age” and “refused to forsake this liberty for commercial earnings, although corporations clamored for his talent” (5).

Corwin himself directly contributed to this anti-corporate mythos. In a 1944 book on radio writing, he advised those aspiring to work in radio to “Do the opposite of what a sponsor or an agency executive tells you, if you want to write originally and creatively” (53), while including regular jabs at network and advertising executives in scripts for sustaining shows such as his “Radio Primer” or “Soliloquy to Balance the Budget.”  But by 1947, Bannerman explains, “the contest for higher ratings” had won out, and Corwin exited the network arena for greener pastures and a new job with the United Nations (10). In a 1951 article for The Writer, Corwin now recommended that “the writer who wants to do the best work in his power, in defiance of formula,” simply “forget radio,” and “until such time as [it] returns to a constructive attitude toward public service and the esthetic values in writing, look upon [it] as a trade outlet, not an art” (1, 3).

Opening lines of February 1951 essay by Corwin for The Writer, in which aspiring writers who wish to exercise their creative freedom are advised to “forget radio” and look elsewhere.

Setting aside the dubious merit of a narrative that denies any real aesthetic achievements for the 15 years preceding and 65 years following Corwin’s ten-year run in network radio–the apogee of a tragically brief “Golden Age”–we may recognize the conception of creativity espoused here as a distinctly Romantic one.  Within this view, so-called “true art” flouts the rules and formulas on which commercially driven mass art depends, and is pursued for purposes other than financial gain. This Romantic ideology of art has been repeatedly challenged, from earlier work by M. H. Abrams, to more recent critiques by Noel Carroll and R. Keith Sawyer. My own concern is not with its veracity per se, but rather with the historical exclusions needed to sustain its underlying binaries of art/commerce and public service/commercialism vis-à-vis the work of Norman Corwin. These exclusions (acts of forgetting on which remembrances of Corwin’s legacy are grounded) may be grouped into three basic categories: the selective operations of canon-formation, cross-fertilization of techniques in commercial and sustaining programming, and profitability of public service within the CBS business model.

Canon-Formation

The received view immediately works to remove Corwin from the sphere of commercial programming, marginalizing his contributions to sponsored series such as the Cresta Blanca Carnival—whose ad agency Corwin himself commended for checking the customary “fear of anything suggesting artistic endeavor” (402)—or Dupont’s Cavalcade of America, for which he wrote his “Ann Rutledge” play, better known from its later revival on the Columbia Workshop. So, too, does it single out among his many production credits a comparatively small list of broadcasts for which he wrote his own scripts, while limiting its purview to his radio works at the expense of his contributions to other media. (For a comprehensive list of Corwin’s creative works, including his many commercial film and television productions, see the appendix in this volume.) As with all processes of canon-formation–a crucial component of what Michel Foucault calls the “author-function”–bids for Corwin’s artistry thus entail a series of selective filtering operations. The totality of the individual’s creative labor is negated within a synecdochical logic of “best” works that renders the exceptional as typical and relegates the typical to the realm of historical oblivion. What other “Corwins” might further scrutiny reveal?

Cross-Fertilization

Efforts to preserve the purity of Corwin’s art by maintaining its opposition to and inherent tension with commercial broadcasting also ignore the extent to which the advertising industry itself embraced Corwin’s techniques. In 1942, trade magazine Broadcasting reported with much clamor Corwin’s acceptance of a bronze medal at New York’s Annual Advertising Awards Dinner, given to honor an “individual, who by contemporary service has added to the knowledge or technique of radio advertising” (22). Authors of popular radio writing manuals noted, in particular, the impact of Corwin’s technique of “choral speech,” which Barnouw in his 1945 Radio Drama in Action claimed was “so successful with listeners that . . . producers of dramatized commercials . . . [now] use [it] for spot announcements to sell soap flakes” (204-5).

Omitted from later accounts, such lost tales of cross-fertilization suggest not simply blind spots in the received view, but a fundamental abnegation: the separation of art and commerce as much an achievement of historical memory as historical fact.

Profitability of Public Service

Positioning the art of Corwin in contradistinction to growing tendencies toward commercialism also ignores the tremendous profitability of public service programming within CBS’s business model, both in its own right and as part of a system of carefully coordinated, cross-platform media flows. As Barnouw notes in Vol. 2 his 1968 History of Broadcasting series, CBS ramped up its investment in sustaining programming during the 1930s as part of a race with NBC to attract affiliates and expand its national network. Whereas NBC charged affiliates for sustaining shows to defray production costs, CBS provided stations with sustaining programs at no charge in exchange for guaranteed carriage of its sponsored series. (NBC stations, by contrast, were given right of refusal for any sponsored shows they wished to opt out of.) For CBS, sustaining shows presented not a financial burden but a path to commercial profitability. Attracting stations eager for free “quality” programming, the network drew fresh revenue in membership fees for each new affiliate it added. Eager to capitalize on these expanded economies of scale and willing to pay the corresponding ad rates, sponsors in turn flocked to the network, giving CBS valuable new accounts and further revenue boosts.

Recognizing their economic value, CBS heavily promoted sustaining stars like Corwin as talented auteurs who represented the network at its best, while working to parlay their products across multiple media platforms. In a 1942 Broadcasting ad promoting Corwin’s newly published script collection, Thirteen by Corwin, the network highlighted his artistry while tracing its corporate signature into his own, reminding readers that these plays were “written and produced under the sponsorship of the Columbia Broadcasting System,” as a new “literature of the air . . . . [whose] first editions . . . [are] printed in decibels instead of type” (62-3).

Images of a well-oiled network publicity machine at work. Newspapers such as the New York Times frequently printed network-supplied publicity stills and promotional copy in their radio sections. Here’s a publicity still of Corwin with actor House Jameson preparing for the the “Soliloquy” episode of Twenty-Six by Corwin (6-15-41).

Corwin’s 1945 VE-Day celebration, “On a Note of Triumph,” was released not only in print, but also on disc by Columbia Records, converting an otherwise ephemeral sustaining feature into a source of direct profit while advancing the larger Columbia brand.

Whether attracting new affiliates and sponsors, or offering opportunities to improve brand recognition and exploit ancillary markets, CBS’s public service programming thus operated not in opposition to commercial forces but rather in the service of the network’s larger bid for economic competitiveness.

Lessons for Radio and Sound Studies

My remarks here are not intended to impugn Corwin’s artistic integrity, nor to imply a lack of commitment to loftier civic goals by CBS executives. The question, again, is a structural one: within what institutional context do the forms of aesthetic expression associated with “the Corwinesque” become possible and desirable? Put simply, how and why, from a structural perspective, do innovations in radio and sound art occur, and what forms can they take under given conditions?

Such inquiries are ill-served by presuming ipso facto oppositions between art and commerce or public service and commercial profit. Indeed, while often resting uneasily together, in the American system they have been bedfellows from the very beginning. To presume, moreover, that aesthetic innovation demands a protected space of noncommercial programming, or that such a space inherently fosters meaningful alternatives to commercial fare, would be a mistake. Within the received view, the legacy of Norman Corwin can be read only as a tale of lament: the death of public service and triumph of commercialism over art. Instead, I suggest we critically interrogate both present and past alike: the “Golden Age” is gone and likely never was, while closer scrutiny of earlier or subsequent eras may reveal aesthetic and institutional complexities hitherto unsuspected.

In a historical moment characterized by an unprecedented proliferation of new media outlets and alternative distribution platforms, but also an extreme concentration of media ownership, can we chart a critical trajectory that avoids both the Scylla of knee-jerk anti-capitalism and Charybdis of hyberbolic neoliberal and techno-utopian praise?

Conflicting attitudes toward contemporary sound industries. User-generated images responding to the SodaHead.com post, “Is Hannah Montana a Tool of the Devil?”, offer excoriating views on the cultural effects of commercialization and conglomeration.

Meanwhile, popular books such as Start and Run Your Own Record Label celebrate opportunities for creative autonomy and aesthetic innovation afforded by niche marketing and digital distribution technologies.

The proper course, whether studying conditions and possibilities for sound art in Corwin’s era or our own, lies somewhere in between.
