(Photo: Shigeko Kubota)MISCONCEPTIONSIn the intervening 31 years, more fiction than fact regardingReuni on has appeared in documents about Cage andDuchamp, even from the pens of authors with prestigiousreputations. Nicolas Slonimsky wrote in the 1978 edition ofBaker’s Biographical Dictionary of Musicians: He [Cage] also became interested in chess and played demon- stration games with Marcel Duchamps [sic], the famous painter turned chessmaster, on chessboards designed by Lowell Cross to operate on aleatory principles with the aid of a computer and a system of laser rays. [2] Cage and Duchamp played only one public “demonstra-tion” game, the one in Reunion, and I have built only onesuch chessboard to date (I am building a second one in1999). We used no computer in conjunction with that chess-board and we used no system of “laser rays.” (My develop-ment of the first “laser light show” began during the follow-ing fall and winter [1968–1969]; I collaborated in that projectwith the sculptor and physicist C.D. Jeffries at the Universityof California, Berkeley and, eventually, with Tudor [3].) In his Cage biography, The Roaring Silence—John Cage: ALife, David Revill wrote: Early in 1968 Cage realized Reunion. A number of sound-sys- tems which operated continuously were prepared by Tudor, Mumma, and David Behrman. The sounds varied according to the position of pieces on a specially prepared chessboard builtLowell Cross (teacher, author, recording producer), School of Music, 2057 Music Build-ing, The University of Iowa, Iowa City, IA 52242-1793, U.S.A.

Cage left the remaining details up tome but told me to contact the Estonian-born Canadian composer Udo Kasemets,who was organizing a festival called“Sightsoundsystems” in Toronto, forwhich Reunion was to be the openingevent (Fig. 3). Chess had been part of Duchamp’severyday life for decades, and in the1960s it became part of Cage’s everydaylife, too. The composer had reveredDuchamp since their first meeting in1942, but kept his distance “out of admi-ration.” Cage eventually found enoughcourage to ask Duchamp for chess les-sons, essentially as a way of getting toknow him [8].

With 16 inputs (allowing four signals each from the four collabo- rating composers) and eight outputs (each directed to a loudspeaker system), the complexity of the sound environ- ment enveloping the audience in- creased as the early part of the game progressed; it then diminished as fewer and fewer pieces were left on the board. I followed no particular plan while connecting the internal components of the chessboard except to ensure that each of the 16 inputs (designated 1–16) could appear at four of the eight differ- ent outputs (designated A–H). For ex- ample, during the course of a game, a signal at input 1 could appear at outputs B, E, F and/or G (see Fig. 6). My ar- rangement was arbitrary, unplanned and quasi-random, but any of the 16 in- Fig. 6.

Ancil-lary effects of sound choices and motionresulted from the shadows of hands andarms as the players moved pieces; theseadditional elements pleased Cage im-mensely. While Reunion was supposed to pro-vide a homey atmosphere, it was alsoquite theatrical, with well-defined rolesfor stars (seated at center stage) and bitplayers. The use of photoresistors, oneimbedded in each of the 64 squares, re-quired that the surface of the board beflooded with bright illumination. Thechessboard was in the spotlight, and sowere the stars. Cage did not wish tomake the lighting requirements an is-sue, but he did tell me, “I’m so glad thatMarcel will be in the spotlight.” The photoresistors and fixed resistorsform a passive resistive matrix (Fig. 7). band attenuation figures (see above), its cided to buy the stars only one bottle ofThe inputs and the outputs are unbal- response is down no more than 0.3 dB at wine (Fig. 9).

THE FIRST GAME Shortly after the announced time of 8:30 P.M. on Tuesday, 5 March 1968, Re- union began. The collaborating compos- ers “gamely” began producing sounds from their own pre-existent works, all of which utilized special equipment built, or custom-modified, by the individual artists themselves.

The works of Behrman, Mumma and Tudor were all examples of “live electronic” music, per formed continuously throughout the evening. My sonic con- tributions were two pieces of pre-re- corded tape music, Video II (B) [12] and Musica Instrument alis, which also pro- duced the oscilloscopic images on the television screens (see Fig. 3). As noted above, Duchamp (White) gave his student-opponent Cage (Black) a handicap in this first game, removing his king’s knight from its square (KN1) and replacing it with a U.S. quarter dol- lar (Fig. 10). With this action, he dem- onstrated his understanding of the func- Fig. 10. The Reunion chessboard in 1998, set up with the Duchamp handicap. (Photo: tion of the chessboard—and, indeed, his Lowell Cross) understanding of the entire event. Duchamp played his role as chess mas- ter that evening with quiet, unruffled dignity, as though the event was nothing more than that intended: a part of every- day life. As reported above, he decisively trounced Cage within about 25 min- utes—the handicap had no bearing on the outcome of that game (Fig. 11). Cage had made a special point of in- viting to Reunion Marshall McLuhan of the University of Toronto, then at the height of his fame as a media guru. McLuhan was one of the composer’s fa- vorite “thinkers” of this period, and I was a student in his seminar “Media and Society” during that 1967–1968 aca- demic year. Udo Kasemets later in- formed me that McLuhan was in the au- dience, remained for the first game, and left immediately thereafter. I never Fig. 11. Marcel Duchamp takes one of John Cage’s pieces.

Then, at about9:15 P.M., the scene reverted to the actualcircumstances of the chess “lessons” atthe Duchamps’ New York townhouseapartment at 28 West 10th Street: Cageplayed Teeny, and Duchamp observed(or dozed off; see Fig. 12). The collabo-rating composers again dutifully pro-vided their electronic signals to the in-puts of the chessboard, while the gamebetween Cage and Teeny went on, andon, and on. They were well matched aschess players, and they played seriouslyand deliberately. Finally, at 1:00 A.M. on 6 March 1968,Duchamp made known his fatigue. Cageand Teeny agreed to adjourn and tocontinue the game in the future. Theevent came to its inconclusive ending.INTERPRETATIONA large part of Cage’s aesthetic of inde-terminacy centered on his wish to re-move his personality from his art.
