Rachel Feltman: For Scientific American’s Science Rapidly, I’m Rachel Feltman.
Loads of us would discover it tough to compose a brand new piece of music beneath any circumstances, even within the prime of our lives. However experimental composer Alvin Lucier is making music from past the grave—at the least in a way of talking.
In a museum in Australia, a latest exhibition allowed guests to listen to sounds generated by neurons grown utilizing the late artist’s blood. The exhibit raised questions on each consciousness and creativity and teased at what turns into attainable when artwork meets cutting-edge neuroscience.

Right here to inform us extra about this musically prolific petri dish is Scientific American affiliate editor Allison Parshall.
Allison, so nice to have you ever again with us.
Allison Parshall: Thanks for having me.
Feltman: So what are we gonna discuss at the moment?
Parshall: At the moment we’re going to speak about some experimental music. What have you learnt about experimental music? What do you consider when you concentrate on it?
Feltman: I positively consider John Cage first. I’m in all probability—I, I wouldn’t say I’m an experimental-music fan, however between having a sister who’s an opera singer and having performed just a little bit of recent dance in faculty with a instructor who beloved Merce Cunningham, I suppose [laughs] I in all probability know just a little bit greater than common. However yeah, I really feel like John Cage is, like, the man.
Parshall: Inform me just a little bit about what you concentrate on with John Cage.
Feltman: I imply, it’s arduous not to consider 4’33” first, his piece that’s merely the ambient silence of a room with an orchestra in it not enjoying.
Parshall: Peak experimental.
Feltman: Yeah, peak experimental. And likewise I really feel like there’s been some nice discourse and argument over, like, what constitutes a sound efficiency of 4’33” [laughs] and, like, what pollutes it. The sound of someone texting—is that an okay factor to have [laughs] in a efficiency of 4’33”? That’s what involves thoughts, for certain.
Parshall: So, like, probably the most experimental you will get: There isn’t a music, or is that music …
Feltman: Proper, yeah.
Parshall: Even when there may be nothing? Yeah, I positively take into consideration 4’33”, additionally, probably the most, and he premiered that in 1952. And it was round that period that some experimental musicians have been beginning to probe into, like, the very nature of sound itself and what counts as music. And there was this one composer—not John Cage—whose work was so methodical it was virtually scientific. He truly used his mind to make music again within the Sixties, and I’ve been completely fascinated by this story for the previous few months, so I’m very excited to get to let you know about it.
Feltman: I’m excited to listen to about it.
[CLIP: Revivification audio]
Parshall: So let me set the scene for you: In Perth, Australia, there’s an artwork museum with a haunting musical exhibit. You begin on the mouth of this darkish, slim hallway. It curves in entrance of you, getting wider because it goes, just like the cochlea construction in your interior ear. The hallway is lined with these square-shaped brass plates that periodically vibrate with sound. The sound is just a little bit completely different in each place that you simply stand within the room as a result of the sound waves are coming from the plates and interacting with one another in a different way all through the area.
No second is identical because the final, and sitting on the middle of the room is a brass plinth beneath a highlight. On the high of the plinth there’s a transparent window, and also you stroll over, and also you look down, and also you see a small dish with a blob that’s only a few millimeters throughout.
These are mind cells, and so they come from the legendary experimental composer Alvin Lucier. He’s lifeless; he handed away in 2021. However you’re surrounded by music that originates from this little organlike construction. It’s known as an organoid.
The method of creating this began with Alvin’s personal blood cells, which have been reworked into stem cells, which have been then become neuronal cells like these within the mind. These mind cells hearth, sending electrical impulses that trigger hammers behind every of the brass plates to strike. Microphones then decide up that sound—and any sound that you simply is perhaps making when you’re within the exhibit—and feed that info as electrical alerts again into Alvin’s mind organoid.
This exhibit is named Revivification for what it makes an attempt to do: revivify Alvin—or at the least some a part of him.
Feltman: Wow, that’s very bizarre and sort of spooky, and I really feel like in all probability has led to loads of debate over the way it matches into his portfolio as an experimental composer. I suppose the primary piece of knowledge to know to get into that debate is: Did he know this was gonna occur? Did he plan for this? Did he …
Parshall: Yeah.
Feltman: Compose the scenario?
Parshall: He was tremendous conscious that this was taking place. In actual fact, it was his thought, or at the least partially his thought, based on his collaborators on the mission.
So I spoke with the opposite artists and the neuroscientists who have been concerned within the exhibit, in addition to one among Alvin’s former colleagues. I additionally spoke along with his daughter, Amanda Lucier; she’s a photojournalist based mostly in Portland. And right here’s what she needed to say on the topic.
Amanda Lucier: There was one thing about the best way that he was that made him suppose and made you suppose that he was by no means gonna die. That makes me smile, desirous about how he pulled off persevering with to work and persevering with to be part of the world of experimental music fairly actually after his dying. I imply, if anybody was gonna pull off immortality, it was him.
Parshall: The story of Revivification, in some ways, truly begins an entire century in the past with the invention of the EEG, or the electroencephalogram.
Feltman: I had a kind of as soon as. It was sort of anticlimactic as a result of the method of getting ready for it’s so dramatic: you get the cap with all of the electrodes, and so they, like, use this bizarre paste to stay it to your head. Then the precise take a look at is simply you sort of sitting there present whereas a pc does one thing that you could’t see—although I do do not forget that the goop does keep in your hair, in order that’s a enjoyable factor that occurs [laughs].
Parshall: I think about that’s no enjoyable to clean out, however I’ve by no means had one earlier than. However they appear sort of cool, when you stated anticlimactic.
An EEG, what it does is measures {the electrical} exercise from the mind from outdoors the cranium, and it’s utilizing, such as you talked about, these electrodes which can be positioned everywhere in the head. And what it’s so good at is capturing real-time info from the mind. So it may possibly seize waves of exercise as networks of neurons hearth in live performance with each other. These waves of exercise, they journey at completely different speeds. So gamma waves are the quickest. They occur while you’re actually targeted or desirous about one thing. Delta are the slowest, and people occur while you’re in, like, a dreamless sleep. And alpha waves, they occur while you’re in a relaxed however awake state, like throughout meditation.
So when EEG was first invented, roughly 100 years in the past, it allowed for the very first recordings of the reside human mind—like, dwelling mind exercise. And so, after all, neuroscientists have been throughout it as a device for unpacking what is definitely occurring within the mind as we do completely different actions. Earlier than they only kinda needed to wait so that you can die after which look what it seemed like.
Within the Sixties it caught the eye of Alvin, who was then a composer on the college at Brandeis College. He was feeling uninspired in his work on the time, however he was completely taken by this expertise.
Alpha mind waves are too low in frequency to be heard by the human ear. We will hear all the way down to, like, 20 hertz, or 20 waves per second. And these waves, alpha mind waves, are typically, like, 10 hertz. However Alvin’s colleagues wished him to file the waves after which manipulate them into one thing that people may hear after which use that audio to create a composition. However he was not enthusiastic about that in any respect. What he wished to do was way more fascinating and experimental.
[CLIP: “Music for Solo Performer” audio]
Parshall: He developed a bit known as “Music for Solo Performer.” Alvin would sit in a chair with EEG electrodes on, in entrance of an viewers, and attempt to meditate. If he was profitable, the low-frequency alpha mind waves can be picked up by the electrodes, amplified after which performed by way of audio system which can be positioned all through the room. The waves would nonetheless be inaudible, however straight in entrance of the audio system can be percussion devices—resembling gongs and cymbals, bass drums, timpanis—and the sound waves would trigger them to vibrate together with the audio system, producing audible noise that the viewers may hear.
There was one thing actually scientific about the best way that Alvin approached composition. Right here’s Susan Leigh Foster. She’s a detailed colleague and buddy of Alvin and his household. A dance professor for years, she taught with Alvin at Wesleyan College, the place he spent most of his profession.
Susan Leigh Foster: This may be possibly a very powerful factor I may say about Alvin [laughs]: he preferred organising situations, or forces, that will then produce sound. In that manner he actually bears loads of similarity to the best way that scientific work is finished. Like, you’ve got a speculation. You arrange the experiment. You conduct the experiment.
You already know, what when you take a sound and ship it down an extended wire after which amplify that after which watch because it adjustments over the hours because the room temperature retains altering and as individuals come into the room and as air currents change, or what when you bury audio system underground, which is a mission he did at Dartmouth.
Parshall: Alvin was at all times listening and observing. Right here’s his daughter once more.
Lucier: I keep in mind being mortified as a middle-school pupil going right into a Pier 1 Imports with some associates, and there was a vacuum going, and he would match the tone of the vacuum to see if he may create beading patterns. So he’d be within the nook there, going, like: [hums note]. And now on reflection I believe, “Oh, wow, that was actually cool for me to have that have.” And on the time I used to be like, “Oh, my God, Dad, even within the Pier 1 Imports.” [Laughs.]
Parshall: Over the course of his profession Alvin turned a well known and revered experimental composer. Man Ben-Ary, one of many artists accountable for Revivification, admired him tremendously.
Man Ben-Ary: I imply, Alvin was one of many biggest composers of the twentieth century. He was not a part of sort of well-liked tradition and never a part of the group of classical composers that, you already know, [were] very well-known. They are saying that he was the composer’s composer.
Parshall: When Man first encountered Alvin’s work within the late 2000s it impressed him to convey sound into his paintings. So then he launched into creating what he known as a kind of unconventional, quote, “self-portrait.”
Feltman: I’ve to surprise what “unconventional” means on this crowd of extraordinarily unconventional individuals [laughs].
Parshall: On this crowd it means taking a biopsy out of your arm, reprogramming your cells into stem cells, which might then turn into any kind of cell in your physique, after which turning these into neurons. In order that’s principally precisely what he did: he cultivated his personal stem cells into neurons, which have been then used to develop a single neural community on a plate, and this had dozens of electrodes on the plate so it may decide up the exercise from the neurons. When the neurons fired they produced alerts that managed analog synthesizers, inflicting them to make sounds or music.
The neural community may additionally obtain alerts from microphones selecting up exterior sound. So Man would usher in reside musicians to improvise along with his neural community in actual time—like, the neural community can be making noise, after which the musicians can be responding to it, after which the neural community would obtain that info and, relying on what you imagine concerning the functionality of those neural networks, responding to it.
He known as the mission CellF, spelled C-E-L-L-F—like “cell F.”
Feltman: Wow.
Parshall: Right here’s a clip. You’ll hear a human drummer, and every part else is from the brain-network synth.
[CLIP: CellF improvising with a drummer at premiere.]
Parshall: Right here’s Man speaking concerning the mission.
Ben-Ary: Conceptually, it was, like, an improv session between two jazz musicians. While you discuss to those that performed with us—we’re speaking about actually good musicians, like, high of their subject internationally—they, all of them, sort of agreed and stated that it was bizarre. There’s one thing that was going there that wasn’t like enjoying with a machine or wasn’t enjoying like with people. It simply responded and behaved in a manner that was just a little bit completely different, and so they couldn’t pinpoint how and why.
Parshall: CellF premiered in 2015, and it toured all over the world. All over the place it went, it carried out with completely different individuals, and Man at all times dreamed of bringing in Alvin to carry out with the exhibit.
Lastly, in 2018, he received a museum curator from St. Petersburg, Russia, to succeed in out to Alvin. And it seems Alvin was completely captivated by the concept, and he agreed to carry out.
Ben-Ary: It was a really humbling expertise. I used to be actually excited. I met one among my all-time musical heroes. I may’ve met Frank Zappa or David Bowie or Alvin Lucier.
Working with him was actually just like working with a grasp. He was actually, actually sensible, and he knew his artwork, and he knew what he wished, and, you already know, we might convey concepts—and he was such a minimalist. You already know, we began with convoluted concepts, and we sort of cleaned it with him actually, actually quick.
Parshall: However Alvin was older—in his late 80s—and he suffered a fall, so that they needed to reschedule the present for later in New York Metropolis. After which COVID hit.
Ben-Ary: After we—the present in New York received canceled, he sort of stated, “Properly, you already know, we will’t try this; let’s do one thing new. Why don’t you are taking my cells?” And it was clear in the direction of a yr into our conferences that the work is about immortalizing Alvin Lucier; that we’re going to immortalize him by way of this organic company; that we’re going to create an entity that will, by way of this company, would proceed his creative legacy—in a really symbolic or conceptual manner, after all.
Parshall: And that was how Revivification got here to be. It was the product of Man, Alvin, the artists Nathan Thompson and Matt Gingold, and the neuroscientist Stuart Hodgetts. Alvin had samples of his blood taken at his dwelling in Middletown, Connecticut, which have been then become stem cells after which right into a tiny cluster of brainlike constructions.
Feltman: So after we say “brainlike constructions,” what do we actually imply?
Parshall: What are we actually that means, certainly …
Feltman: What are the blobs [laughs]?
Parshall: [Laughs] What are the blobs? The blobs are sort of just like what Man did for CellF, which was that community of neurons which can be wired collectively, besides on this case the constructions function a number of networks which can be three-dimensional. So it’s sort of like scaling up what he already did with CellF.
Feltman: Mm.
Parshall: The neurons are usually immature as a result of they’re so younger, and so they have fewer connections than most neurons in your mind. However these organoids do, in some methods, mimic a creating human mind, so that they’re actually helpful for scientists who’re making an attempt to review what occurs because the mind types. Generally individuals name them “mini brains,” however Stuart is emphatically in opposition to that time period.
Stuart Hodgetts: It’s necessary to essentially stress that these organoids are under no circumstances wherever near being what the mind is at that stage of improvement, however they do recapitulate loads of early mind improvement, in phrases that they type comparable constructions. However they’re extraordinarily rudimentary. They don’t comprise a vascular system. They don’t comprise the entire completely different cell sorts that you simply’d discover in a mind.
Parshall: However these networks of neurons do hearth collectively, and they are often stimulated with electrical energy to answer that enter. So in that manner they’re sort of reacting to their, quote, unquote, “setting.”
That’s how Alvin’s mind organoids, that are within the plinth within the middle of the curved room on the exhibit in Perth, produce and probably reply to sound. The sound that’s created within the gallery will not be predictable—you would file it for hours or stand there for hours, and also you wouldn’t actually hear it repeat.
Feltman: Yeah, kinda makes you surprise what these organoids are able to.
Parshall: It actually does make you surprise what they’re able to, and it’s attainable that the evolution of sound within the exhibit is one thing you would name “studying,” quote, unquote, in some, like, unfastened measure of the phrase.
Researchers learning organoids or very comparable sort of brain-on-a-chip constructions have discovered that they are often hooked as much as programs and seemingly modify their outputs to attain sure outcomes. So in 2022 researchers claimed to have demonstrated {that a} brain-on-a-chip may be taught to play Pong.
Feltman: I do not forget that one, yeah.
Parshall: Yeah, and it, like, developed the power to maneuver the sport’s paddle. One other group revealed a 2023 research that advised mind organoids may type audio clips of individuals saying Japanese vowels.
These are all sort of duties which can be considerably analogous to what a rudimentary AI system may do. But it surely’s additionally one thing that’s simply wholly completely different from AI. Right here’s Stuart once more.
Hodgetts: So this isn’t synthetic intelligence in any respect. That is one thing that’s naturally inherent in these neural networks. And if they’re exhibiting the power to reply and react to their setting over time, at some fundamental stage, you may assign the phrase “intelligence” to that, so we name it “in-vitro intelligence.”
Parshall: The phrases “intelligence,” “studying,” all of them ascribe a sure thought of intention to those programs, like they’re doing one thing with a objective, though that’s not essentially what we expect is occurring or know is occurring.
Feltman: Proper. So what is occurring?
Parshall: These findings that mind organoids can, quote, unquote, “be taught” stay fairly controversial. To determine what to make of them I reached out to Kenneth Kosik, a neuroscientist on the College of California, Santa Barbara.
Kenneth Kosik: I believe we’re very near with the ability to display that organoids do have some capability for studying. After which it will depend on how loosely you employ the phrase. You already know, your liver learns to acknowledge [laughs] sure meals or medication, and it adapts, and it turns into tailored to one thing, so studying is a really—it’s a phrase with loads of comfortable edges round it. Slime molds be taught, so studying wouldn’t shock me. Some individuals already declare that such a factor occurs, and, you already know, I don’t disagree. However the consciousness query may be very arduous.
Parshall: The consciousness query, that’s sort of what’s lingering at the back of all of our minds, proper?
Feltman: Yeah, and it’s positively what makes the exhibit really feel sort of spooky.
Parshall: It does really feel spooky. I imply, does this mind organoid have an inner world—like, a way of itself? Does it have company? Might it ever have company? Like, when you hooked it as much as the suitable outputs, may it take over the world?
The reply’s no, at the least so far as we all know. I imply, the consensus amongst neuroscientists is that mind organoids aren’t even near consciousness but, and their reasoning is principally that neuroscientists perceive consciousness by way of the constructions in our mind that enable it to exist. And these are sure areas and networks that we imagine all work collectively within the mind to keep up a state of consciousness. It’s not only one area, in the identical manner that, like, a automobile engine doesn’t run based mostly off of only one half.
Feltman: Mm.
Parshall: It’s sort of the entire coming collectively from the elements, at the least so far as we all know. Mind organoids don’t actually have all of these constructions.
However on the identical time we’re basing our understanding on what consciousness relies off of our personal consciousness in people, which is the one one we will actually ensure of. Who’s to say it’s the one manner it may possibly work? We sort of don’t know that. So on this context it makes good sense to be nervous about what these mind organoids may sooner or later be able to, which we will’t totally admire proper now. That’s a part of what the artists behind Revivification wish to encourage us to consider.
Ben-Ary: I believe probably the most fascinating query for me is how a lot of Alvin is encapsulated on this organoid. You already know, whether or not there’s a filament of reminiscence, one thing that was maintained by way of this organic transformation, this entire chemical course of of remodeling blood to a mind, a filament of reminiscence on a molecular stage, possibly, that was sort of passing by way of and maintained by way of these organic and chemical processes and was retained within the organoid itself.
Now, it is a philosophical query. Scientists would say, “Ah, yeah, there’s nothing.” And I don’t suppose that that’s fascinating, to consider it this fashion. I believe that it’s actually fascinating to consider the poetics round it, and I believe that it’s very fascinating to consider this hypothesis that sooner or later possibly one thing can be retained.
Parshall: I believe that’s a part of what I really like a lot about this story. It’s that utilizing artwork to disclose one thing concerning the bodily world, like this Revivification exhibit appears to do, is simply so quintessentially Alvin. In speaking to the individuals who beloved and admired him I simply heard consistently about his manner of observing the legal guidelines of physics and organising systematic situations to permit these legal guidelines to simply create fascinating music.
Lucier: I imply, there may be loads of sitting in absolute silence when his work is being carried out, and that’s the absolute silence in your self—not rustling your shirt or uncrossing your legs and making even the smallest bang—as a result of the factor that you simply’re listening for is the composition or the best way that the area is revealing itself due to the best way sound is shifting round it.
Parshall: On this manner, too, Revivification is very like Alvin’s most well-known piece, which additionally impressed Man. It’s known as [I Am] Sitting in a Room. It was composed in 1969, just a few years after the EEG work. And the start of the piece truly explains its personal conceit very nicely, so right here’s a recording from 1981 with Alvin talking.
[CLIP: Alvin Lucier performing I Am Sitting in a Room: “I am sitting in a room different from the one you are in now. I am recording the sound of my speaking voice, and I am going to play it back into the room again and again until the resonant frequencies of the room reinforce themselves so that any semblance of my speech, with perhaps the exception of r-r-r-rhythm, is destroyed.”]
Parshall: It’s a 45-minute-long recording. He repeats this course of many instances. So to display the way it progresses I’m simply gonna take that first line, “I’m sitting in a room,” and present you the way it adjustments each time he repeats it.
[CLIP: “I am sitting in a room” line repeated]
Parshall: Rachel, how do you’re feeling?
Feltman: It’s actually otherworldly, and it makes me actually want I used to be in Australia and might be within the presence of Alvin’s cells [laughs] whereas they make music. However yeah, I believe it raises questions, not nearly what music is however, like, what consciousness is. In order that’s fairly cool for an artwork mission. I might say that’s a fairly profitable artwork mission [laughs].
Parshall: I really feel like he was at all times—I imply, I say this as if I knew him. At this level I simply really feel like I’ve been desirous about him for some time. It’s virtually like, “Oh, I want I may have met him.” But it surely looks like he would take these massive questions, and he would simply drill down into what makes them important, provide you with these, like, situations to make that property into one thing stunning. And I believe that’s simply what I respect about it a lot.
So by the tip of that [I Am] Sitting in a Room, what you’re listening to, the precise warbles of it, are a property of the room. They’re a property of the best way that sound resonates in that area. So in every single place you carry out it, it’s gonna sound just a little bit completely different.
Feltman: Mm.
Parshall: In that manner it’s not too completely different from 4’33” [laughs].
Feltman: [Laughs.] Each dialog about experimental music has to finally come again to 4’33”.
Parshall: Amanda Lucier advised me that there’s an image of her someplace as a baby sitting on John Cage’s lap, so that they have been all operating in the identical circles.
Feltman: Properly, Allison, thanks, as at all times, for approaching and for sharing some fascinating stuff with us.
Parshall: You’re welcome. I’m very comfortable to be on the casual Science Rapidly music beat.
