A crowd gathered on the MIT Media Lab in September for a live performance by musician Jordan Rudess and two collaborators. Certainly one of them, violinist and vocalist Camilla Bäckman, has carried out with Rudess earlier than. The opposite — a man-made intelligence mannequin informally dubbed the jam_bot, which Rudess developed with an MIT group over the previous a number of months — was making its public debut as a piece in progress.
All through the present, Rudess and Bäckman exchanged the indicators and smiles of skilled musicians discovering a groove collectively. Rudess’ interactions with the jam_bot recommended a special and unfamiliar sort of trade. Throughout one duet impressed by Bach, Rudess alternated between taking part in a couple of measures and permitting the AI to proceed the music in an identical baroque fashion. Every time the mannequin took its flip, a variety of expressions moved throughout Rudess’ face: bemusement, focus, curiosity. On the finish of the piece, Rudess admitted to the viewers, “That may be a mixture of an entire lot of enjoyable and actually, actually difficult.”
Reflections on Jordan and the jam_bot

Rudess is an acclaimed keyboardist — the perfect of all time, in accordance with one Music Radar journal ballot — recognized for his work with the platinum-selling, Grammy-winning progressive steel band Dream Theater, which embarks this fall on a fortieth anniversary tour. He’s additionally a solo artist whose newest album, “Permission to Fly,” was launched on Sept. 6; an educator who shares his expertise via detailed on-line tutorials; and the founding father of software program firm Wizdom Music. His work combines a rigorous classical basis (he started his piano research at The Juilliard Faculty at age 9) with a genius for improvisation and an urge for food for experimentation.
Final spring, Rudess turned a visiting artist with the MIT Middle for Artwork, Science and Know-how (CAST), collaborating with the MIT Media Lab’s Responsive Environments analysis group on the creation of recent AI-powered music know-how. Rudess’ most important collaborators within the enterprise are Media Lab graduate college students Lancelot Blanchard, who researches musical functions of generative AI (knowledgeable by his personal research in classical piano), and Perry Naseck, an artist and engineer specializing in interactive, kinetic, light- and time-based media. Overseeing the undertaking is Professor Joseph Paradiso, head of the Responsive Environments group and a longtime Rudess fan. Paradiso arrived on the Media Lab in 1994 with a CV in physics and engineering and a sideline designing and constructing synthesizers to discover his avant-garde musical tastes. His group has a convention of investigating musical frontiers via novel person interfaces, sensor networks, and unconventional datasets.
The researchers got down to develop a machine studying mannequin channeling Rudess’ distinctive musical fashion and method. In a paper revealed on-line by MIT Press in September, co-authored with MIT music know-how professor Eran Egozy, they articulate their imaginative and prescient for what they name “symbiotic virtuosity:” for human and laptop to duet in real-time, studying from every duet they carry out collectively, and making performance-worthy new music in entrance of a dwell viewers.
Rudess contributed the information on which Blanchard educated the AI mannequin. Rudess additionally supplied steady testing and suggestions, whereas Naseck experimented with methods of visualizing the know-how for the viewers.
“Audiences are used to seeing lighting, graphics, and scenic components at many live shows, so we wanted a platform to permit the AI to construct its personal relationship with the viewers,” Naseck says. In early demos, this took the type of a sculptural set up with illumination that shifted every time the AI modified chords. Throughout the live performance on Sept. 21, a grid of petal-shaped panels mounted behind Rudess got here to life via choreography primarily based on the exercise and future technology of the AI mannequin.
“In the event you see jazz musicians make eye contact and nod at one another, that provides anticipation to the viewers of what’s going to occur,” says Naseck. “The AI is successfully producing sheet music after which taking part in it. How can we present what’s coming subsequent and talk that?”
Naseck designed and programmed the construction from scratch on the Media Lab with help from Brian Mayton (mechanical design) and Carlo Mandolini (fabrication), drawing a few of its actions from an experimental machine studying mannequin developed by visiting pupil Madhav Lavakare that maps music to factors transferring in house. With the flexibility to spin and tilt its petals at speeds starting from refined to dramatic, the kinetic sculpture distinguished the AI’s contributions in the course of the live performance from these of the human performers, whereas conveying the emotion and vitality of its output: swaying gently when Rudess took the lead, for instance, or furling and unfurling like a blossom because the AI mannequin generated stately chords for an improvised adagio. The latter was one in all Naseck’s favourite moments of the present.
“On the finish, Jordan and Camilla left the stage and allowed the AI to completely discover its personal course,” he recollects. “The sculpture made this second very highly effective — it allowed the stage to stay animated and intensified the grandiose nature of the chords the AI performed. The viewers was clearly captivated by this half, sitting on the edges of their seats.”
“The objective is to create a musical visible expertise,” says Rudess, “to indicate what’s doable and to up the sport.”
Musical futures
As the place to begin for his mannequin, Blanchard used a music transformer, an open-source neural community structure developed by MIT Assistant Professor Anna Huang SM ’08, who joined the MIT school in September.
“Music transformers work in an identical means as giant language fashions,” Blanchard explains. “The identical means that ChatGPT would generate essentially the most possible subsequent phrase, the mannequin we have now would predict essentially the most possible subsequent notes.”
Blanchard fine-tuned the mannequin utilizing Rudess’ personal taking part in of components from bass strains to chords to melodies, variations of which Rudess recorded in his New York studio. Alongside the way in which, Blanchard ensured the AI could be nimble sufficient to reply in real-time to Rudess’ improvisations.
“We reframed the undertaking,” says Blanchard, “by way of musical futures that have been hypothesized by the mannequin and that have been solely being realized in the meanwhile primarily based on what Jordan was deciding.”
As Rudess places it: “How can the AI reply — how can I’ve a dialogue with it? That’s the cutting-edge a part of what we’re doing.”
One other precedence emerged: “Within the area of generative AI and music, you hear about startups like Suno or Udio which might be capable of generate music primarily based on textual content prompts. These are very attention-grabbing, however they lack controllability,” says Blanchard. “It was necessary for Jordan to have the ability to anticipate what was going to occur. If he might see the AI was going to decide he didn’t need, he might restart the technology or have a kill change in order that he can take management once more.”
Along with giving Rudess a display screen previewing the musical choices of the mannequin, Blanchard constructed in numerous modalities the musician might activate as he performs — prompting the AI to generate chords or lead melodies, for instance, or initiating a call-and-response sample.
“Jordan is the mastermind of all the pieces that’s taking place,” he says.
What would Jordan do
Although the residency has wrapped up, the collaborators see many paths for persevering with the analysis. For instance, Naseck wish to experiment with extra methods Rudess might work together instantly along with his set up, via options like capacitive sensing. “We hope sooner or later we’ll have the ability to work with extra of his refined motions and posture,” Naseck says.
Whereas the MIT collaboration targeted on how Rudess can use the instrument to reinforce his personal performances, it’s straightforward to think about different functions. Paradiso recollects an early encounter with the tech: “I performed a chord sequence, and Jordan’s mannequin was producing the leads. It was like having a musical ‘bee’ of Jordan Rudess buzzing across the melodic basis I used to be laying down, doing one thing like Jordan would do, however topic to the easy development I used to be taking part in,” he recollects, his face echoing the delight he felt on the time. “You’re going to see AI plugins to your favourite musician which you could carry into your individual compositions, with some knobs that allow you to management the particulars,” he posits. “It’s that sort of world we’re opening up with this.”
Rudess can be eager to discover instructional makes use of. As a result of the samples he recorded to coach the mannequin have been just like ear-training workout routines he’s used with college students, he thinks the mannequin itself might sometime be used for educating. “This work has legs past simply leisure worth,” he says.
The foray into synthetic intelligence is a pure development for Rudess’ curiosity in music know-how. “This is the subsequent step,” he believes. When he discusses the work with fellow musicians, nevertheless, his enthusiasm for AI typically meets with resistance. “I can have sympathy or compassion for a musician who feels threatened, I completely get that,” he permits. “However my mission is to be one of many individuals who strikes this know-how towards constructive issues.”
“On the Media Lab, it’s so necessary to consider how AI and people come collectively for the good thing about all,” says Paradiso. “How is AI going to raise us all up? Ideally it’ll do what so many applied sciences have achieved — carry us into one other vista the place we’re extra enabled.”
“Jordan is forward of the pack,” Paradiso provides. “As soon as it’s established with him, folks will observe.”
Jamming with MIT
The Media Lab first landed on Rudess’ radar earlier than his residency as a result of he wished to check out the Knitted Keyboard created by one other member of Responsive Environments, textile researcher Irmandy Wickasono PhD ’24. From that second on, “It’s been a discovery for me, studying concerning the cool issues which might be happening at MIT within the music world,” Rudess says.
Throughout two visits to Cambridge final spring (assisted by his spouse, theater and music producer Danielle Rudess), Rudess reviewed ultimate initiatives in Paradiso’s course on digital music controllers, the syllabus for which included movies of his personal previous performances. He introduced a brand new gesture-driven synthesizer known as Osmose to a category on interactive music programs taught by Egozy, whose credit embrace the co-creation of the online game “Guitar Hero.” Rudess additionally supplied tips about improvisation to a composition class; performed GeoShred, a touchscreen musical instrument he co-created with Stanford College researchers, with pupil musicians within the MIT Laptop computer Ensemble and Arts Students program; and skilled immersive audio within the MIT Spatial Sound Lab. Throughout his most up-to-date journey to campus in September, he taught a masterclass for pianists in MIT’s Emerson/Harris Program, which supplies a complete of 67 students and fellows with help for conservatory-level musical instruction.
“I get a sort of rush every time I come to the college,” Rudess says. “I really feel the sense that, wow, all of my musical concepts and inspiration and pursuits have come collectively on this actually cool means.”
