I. The Coffin
I was eight or nine. My brother's guitar teacher, a man named Nino Getts, offered to teach me banjo. He arrived in a dying red Jaguar from the 1960s, leather jacket, and carried to our door what looked like a child-sized coffin. The case was ancient—tattered leather splitting at the seams, exposing patches of cheap wooden frame beneath, the kind of object you find in the back of an estate sale that no one bids on. I knelt on the living room carpet and worked the latches. They were rusted shut, each one requiring both thumbs and a violence that felt ceremonial, like breaking seals on a tomb. The lid resisted, then gave.
The smell hit first. A century of trapped air—basement floods, mildew, the sour breath of a mouth sealed since the Harding administration. Decaying flaps of saffron plush lining hung from the lid's interior like strips of flesh peeling from bone. The velvet had gone to dust in patches, exposing the raw wood beneath. Everything about the case said: what is inside this has been buried, forgotten, left for dead.
But the banjo—the banjo was alive. The hardware gleamed. The pearloid inlay along the neck caught the living room light and scattered it, nacreous, iridescent, dancing. A 1921 Paramount tenor banjo, ninety years old and luminous inside its rotting sarcophagus.
A tenor banjo. Four strings. Not the five-string I wanted—not the bluegrass banjo with the short drone string and the clawhammer roll. The tenor was a different instrument entirely: a dead technology from the ragtime and dixieland era, designed to acoustically cut through a loud brass band. Four strings, tuned in fifths like a viola, no drone, no clawhammer. I didn't know any of this. I didn't know the difference between a tenor and a five-string. I just knew the instrument Nino handed me wasn't quite the one I heard in my head. It would take years—and thank God for the internet—before I found my way to the real instrument. In the meantime, I quickly picked up ukulele, harmonica, and guitar, circling the thing I wanted without being able to name it.
The very first song Nino taught me was Tom Dooley—a murder ballad about a man sentenced to hang for the double murder of his wife and her lover caught in the act.
This necromancy was my initiation. The instrument arrived not as a tool but as an exhumation. The coffin case, the century-old stench, the gleaming hardware inside the decay, and the first words it taught me to sing were about killing and dying. I did not know that murder ballads would become a lifelong obsession, that I would build a generative songwriting game from the Roud Folk Song Index, that the card-based system I describe in Essay 5 would emerge from decades of living inside the tradition that Tom Dooley began. I did not know that the banjo would become the center of a musical life spanning four traditions across three continents. I only knew that when I opened that case, something woke up.
II. The Session Circle
I started jamming when I was fourteen, at the Staten Island Bluegrass Festival. Then I got hip to the scene in the West Village. I went to an event in Washington Square Park that was a reunion for all the pickers who used to converge there every Sunday starting in the early 1960s—someone told me not to play, that this event wasn't for me. But the energy was unforgettable. It was like time reanimated, overlapping in this strange way, echoes of the Greenwich Village folk revival occupying the same coordinates where the revival had happened decades before. The park was a chronotope—the same benches, the same fountain, the same circle formation, but the bodies were older and the city around them had changed and the music was both the same and not the same.
I worked up my playing alone, with jam-along CDs that provided a backing band for fundamental fiddle tunes at different tempos. I didn't have friends to play with. Then came the point I was finally ready to check out the downtown picking parties at the Baggot Inn—old-time session in the front room, bluegrass in the back, and sometimes a splinter jam of hotshots like Chris Thile and Mark O'Connor in the middle.
The first time I went, my mom had to bring me because I was underage.
After that, I had to start sneaking into bars so I could participate. I tried keeping a low profile, showing up before the bouncer went on duty. Sometimes this worked. Then I tried a fake ID. Then my brother's fake ID. Then his real ID when he turned twenty-one—which failed spectacularly the night he showed up to see me and they had his license behind the bar. And then the leader of the session, Sheriff Bob—Bob Saidenberg, an elderly Picasso-collection-heir trust fund kid, MIT dropout, dilettante filmmaker, but a total fixture in the scene, known as "the Sheriff of Goodtimes"—took a shine to me. One night after I'd been booted again, he was outside having a smoke, and he told the bouncer I was his nephew.
Then I was in.
What I was in was a horizontal organism. No conductor. No score. No hierarchy of chairs. The bluegrass session circle is an amoeba—self-regulating, leaderless, the roles distributed across the bodies in the circle like organs in a single creature.
The bass always has the 1 and the 3—the gravitational floor. The mandolin chops on the upbeats—the rhythmic counterweight. The guitar's strum ties those two together, emphasizing strong and weak beats in a pattern that braids the bass's ground to the mandolin's air. The fiddle provides pads or the vocal lead identity. And the banjo—the banjo is the glue. The perpetual motion machine. It braids together subdivisions of rhythm through harmonic and melodic information simultaneously, a continuous stream that holds the whole organism together. During a vocal song, usually only one player plays fills, and if they have to step away from their rhythmic duty to do it, someone else covers that role. The organism compensates. The amoeba shifts.
One of the banjoist's main responsibilities is to kick off tunes. It took me years of fumbling to master this. You tell everyone the key. You signify whether it's a full-form intro or an abbreviated turnaround—a 1-5-1 in Nashville numbers. The vocabulary for kickoffs has a fiddle language and a banjo language, but it breaks down to standard phrases with nicknames: "Son-of-a-bitch, I'm tired!" for the canonical banjo kickoff lick. Not knowing a song is rarely a problem, because these songs are all variations of the same nuclear DNA of core repertoire and form. The vocabulary is finite. The combinations are infinite. Essay 5's constraint architecture, performed live in a circle.
The contrast with the pit orchestra is total. The pit is vertical—a conductor on a raised platform, a score that determines every note, a hierarchy of chairs, the audience invisible above you. The session circle is horizontal—no conductor, no score, the audience is anyone who walks past. In the pit, you follow. In the circle, you negotiate. In the pit, the architecture is given. In the circle, the architecture emerges from the negotiation between bodies.
Both are distributed consciousness—Essay 9's argument. But the quality of the distribution is different. The pit's consciousness is conducted. The circle's consciousness is grown. The pit is a designed system. The circle is an evolved one.
III. The Classical Guitar as Spatial Navigation
My father was enchanted by classical guitar. He had tried his hands at it when he was young, and the instrument was in the house before I ever studied it—a Bream CD that contained Paganini's solo guitar concerto and the Spanish repertoire: Recuerdos de la Alhambra, Granada, Leyenda. The music was in my ears from childhood, inherited desire before it was a practice.
In high school I went to a precollege program at the Manhattan School of Music—hard, the kids immensely talented. I was in jazz bands and concert bands where I played crotales with a bow, anvil, tympani, auxiliary percussion. I was always in choir and chamber chorus. At Oberlin I sang in Round Midnight, a co-ed jazz-folk a cappella group named for the Monk tune. I arrived at Oberlin intending the double-degree program as a jazz guitar major, studying with Bobby Ferazza, the head of the jazz department. But early on I was fighting to transmute my conservatory studies toward my acoustic music practice—I was already an accomplished flatpicker on guitar and mandolin, and banjo was always the most passionate practice.
My closest musical mentor outside of school was Noam Pikelny of the Punch Brothers. Chris Eldridge, also a Punch Brother, was an Oberlin alum who had managed to turn his conservatory studies toward his guitar practice, and that path was a model for me. Noam and I would spend hours arranging Bach violin partitas for banjo tablature—the most intense work I have ever done. We discussed PhD-level systems design for how to map the ergonomics of the hand and shifting economy to the left and right hand of the banjo. The work I put into the instrument would have resulted in my becoming a first-rate violinist or classical guitarist or master of anything with more fluidity. But we had to fight the instrument for this expression. It was fun. It was exciting. It was frontier. It didn't make sense. Since the Punch Brothers worked so closely with Chris Thile, whose musical mind is like a beehive, they developed his work ethic, practice systems, phrasing concepts. That was what I wanted. I wanted to embody all of the Punch Brothers.
And then Steve Aron, the chair of the classical guitar department at Oberlin, saw my hands. I demonstrated some banjo chops for him, then ripped Jerry's Breakdown—a Jerry Reed / Chet Atkins tune—on guitar. He recognized what the banjo had built in my hands and assigned me hard repertoire: a huge book of studies by Frederick Noad, and of course Recuerdos de la Alhambra, Granada, and Leyenda, which I had already been playing around with for years.
During my junior year I found a VHS in a free giveaway bin at the conservatory library—headed for the trash heap. Julian Bream's Guitarra. I took it home and watched a man play Albéniz inside the architecture the music describes. The Alhambra while playing Recuerdos de la Alhambra. The cinematography was gorgeous—Bream playing amidst old Spanish heritage sites, places that the music was written to characterize. Albéniz's music sought to capture Spanish place-identity with such depth that hearing it performed inside the places it describes was like watching a chronotope fold in on itself—the temporal form and the spatial origin occupying the same coordinates simultaneously.
This was classical guitar as spatial navigation. The Spanish repertoire is place-music. Recuerdos de la Alhambra is literally "Memories of the Alhambra"—a memory palace stated as a tremolo. And I encountered this while deep in the work of fighting the banjo for expression it wasn't built to give—arranging Bach partitas for an instrument that resists every measure. What Bream showed me was the other side: an instrument designed for this literature, a body and instrument and architecture aligned into a single system.
Two instruments. Two relationships to constraint. The banjo forces you to build the path through territory the instrument was never mapped for. The classical guitar is the path—shaped over centuries for exactly this literature, this body position, this repertoire. The navigation is different because the constraint is different. And both of them, I would later understand, are the thaumotrope: the body on one side, the instrument on the other, and the music produced by the spinning between them.
IV. Cyclical Time: The Hindustani Body
At Oberlin I studied with Hasu Patel, one of the first women to make a name in Hindustani sitar playing in India, a disciple of the legendary Vilayat Khan. She led a program in the Experimental College—for-credit courses, one or two credits per term. I took everything she offered: sitar, tabla, vocal. I helped administer the classes and ran extra practice sessions for students. The school had a wonderful collection of instruments available to us.
Hasu Patel conducted the rooms under very strict decorum. No shoes. Never step over an instrument. The reverence for how to treat these things—as vessels of holy expression. This was the guru-shishya tradition: you learn by sitting with the teacher, absorbing through proximity and repetition, the same way I had learned banjo in the session circle but formalized into a spiritual discipline.
What entered my body from Hindustani music was a completely different relationship to time. Cyclical time. Tala—the number of beats in the cycle. In the Western music I had trained in, time moves forward: verse, chorus, bridge, resolution. In Hindustani music, time wheels. The cycle comes around again and again, and the phraseology maps to the cycle differently in each revolution.
The tihai—a rhythmic phrase repeated three times, calculated so the final note lands precisely on sam, the one of a new cycle. The math has to be exact: phrase length times three repetitions, plus the rests between them, equals exactly the remaining beats in the cycle. It always felt like the execution of a computer program. This was something I had to learn to feel in my body rather than calculate in my head.
And then the chakkardar—the tihai of tihais. The three-repetition pattern nested inside a larger three-repetition pattern, both computed to resolve on sam. Fractal rhythm. The same structure at two scales simultaneously. Alison's fractal narrative shape from Essay 5—the part recapitulating the whole—performed as rhythmic practice.
Harmony takes a total backseat in this music and melts into the background. Rhythm IS the melody. This was the opposite of everything my bluegrass body knew. In the session circle, the three-chord palace from Essay 19 drives everything—I-IV-V, the harmonic architecture that gives each song its shape. In Hindustani music, the harmonic architecture dissolves and what remains is the cycle, the computation, the body's feel for where sam will arrive.
I continued studying in New York with Krishna Bhatt, Snehashish Mozumder, and the legendary Kala Ramnath. I was part of a scene called the Brooklyn Raga Massive—musicians blending Indian classical with Western forms. And I did a gurukul in rural India, on an ashram campus, with a group of picker friends, to work with Kala. The two musical worlds physically converging—Western string players sitting in the traditional residential study format, studying Hindustani music in the setting it was designed for.
The same hands that fought the banjo for every note of Bach. The same body that felt the session circle's horizontal amoeba. Now sitting cross-legged on an ashram, feeling cyclical time wheel through the body, the tihai landing on sam, the instrument across the lap instead of propped on the knee.
V. The Convergence
In 2014, at the very first Freshgrass Banjo Competition at Mass MoCA, I brought a tabla player.
I performed an extremely advanced arrangement of Brown County Breakdown—a fiddle tune—using Hindustani rhythmic systems. The tihai and the fiddle tune occupying the same temporal coordinates. The cycle and the form. Two computational systems braided together on a five-string banjo with tabla accompaniment at a bluegrass competition.
I also performed an original composition—a piece of extreme complexity that had emerged from arranging Barrios's "Las Abejas" for banjo. I called it "The Secret Life of Bees." It was a musette—a mix of Bach and Barrios and choro on a five-string banjo with tabla. The classical guitar repertoire, the Hindustani rhythmic architecture, the Brazilian tradition, and the banjo's fifth-string drone, all coexisting in a single performance.
I executed it masterfully.
I won third place.
Third place was ridiculous. But it was also the right result, because the judging frame—a banjo competition—didn't have a category for what I brought. The judges were scoring bluegrass banjo playing. I was performing four musical traditions simultaneously on an instrument designed for one of them. The frame couldn't hold the content. Essay 18's Carrollian insight: the form was running, the rules were executing, but the content had outgrown the container.
VI. Four Computational Systems
Here is what the body learns from carrying four musical traditions simultaneously.
The session circle teaches you that distributed consciousness is horizontal. No conductor, no score, the amoeba self-regulates. Intelligence is in the coupling between bodies, not in any single body's command. The vocabulary is finite—the same fiddle tunes, the same kickoff phrases, the same nuclear DNA of form—but the combinations are infinite. This is Essay 5's constraint architecture: the fifth string is what makes the banjo a banjo, and the session circle's conventions are what make it a session circle. Without them, you have noise. With them, you have a self-organizing organism.
The classical guitar teaches you that spatial navigation is musical navigation. The Spanish repertoire is place-music—Albéniz encoding the identity of a specific architecture into temporal form. Bream playing inside the architecture the music describes is the chronotope from Essay 3 made audible. The instrument is designed for this literature. The body, the guitar, and the repertoire are aligned into a system. The navigation is fluid because the constraint was built for the path.
The Hindustani tradition teaches you that time is cyclical, not linear. The tihai is a computer program executed by the body. The chakkardar is a fractal—the part containing the whole, the whole containing the part. Rhythm IS melody. Harmony dissolves. What remains is the cycle, the computation, and the body's feel for where sam will arrive. This is a completely different embodied epistemology from anything the Western tradition offers.
And the banjo—the banjo teaches you to fight. The instrument was not designed for Bach or Barrios or Hindustani systems. Every note of that literature has to be invented on the neck, the ergonomic mapping worked out by hand, the path built where no path exists. The banjo is the frontier instrument. It forces you to invent the navigation rather than inherit it.
But the banjo's frontier quality is not accidental. It is historical. The banjo is an African instrument—descended from the akonting, the ngoni, the xalam. A gourd body, a skin head, a stick neck. It crossed the Atlantic in the bodies of enslaved people, carrying with it a musical architecture that was non-linear, non-Western, built around the open drone and the rhythmic complexity that the fifth string enables. The very features that make the banjo a banjo—the short drone string, the clawhammer stroke, the open tuning, the instrument's resistance to European harmonic conventions—are the African inheritance.
In the late nineteenth century, a deliberate campaign was mounted to purge the instrument of these roots. Karen Linn's That Half-Barbaric Twang documents the gentrification: the five-string banjo "elevated" from its minstrel tradition into white parlor respectability, the clawhammer technique suppressed in favor of classical fingerstyle, the repertoire redirected from field hollers and dance tunes toward drawing-room compositions. The "barbaric" element—the African element, the drone, the rhythmic drive, the rough timbral attack—was what they tried to civilize out of it. And the "barbaric" element was the productive constraint. Civilize it away and you have a parlor instrument with no voice. Keep it and you have the most distinctive sound in American music.
And within that African-descended architecture lives its own internal mathematics. Scruggs style—the three-finger picking technique that Earl Scruggs codified and that became the backbone of bluegrass banjo—is a combinatorial engine: three fingers navigating five strings. The permutations of which finger strikes which string in what order generate the rolling patterns that define the sound. Forward roll, backward roll, alternating thumb, inside-out—each one a different algorithmic path through the same five-string, three-finger constraint. This is the banjo's own computational system, unique to its specific affordances, and it resonates with the systems I would encounter years later in Hindustani music: the tihai's three repetitions resolving on sam, konnakol's syllabic subdivision of the beat. Three fingers, three repetitions, three trials. The number of ritual, the number of constraint, the number that makes the pattern.
My practice—bringing Bach, Barrios, Hindustani rhythmic systems, and choro to the five-string—is the opposite of that nineteenth-century gentrification. I am not "elevating" the banjo to European standards. I am bringing the world's musical traditions to the instrument's African-descended architecture, working with the fifth string rather than removing it, composing within the constraint rather than against it. The frontier is not the instrument's limitation. The frontier is the meeting point between the African design and everything I carry to it.
Four systems. Four bodies. All carried in the same hands.
The pit orchestra's body follows a conductor. The session circle's body negotiates with equals. The classical guitarist's body navigates aligned terrain. The Hindustani musician's body computes cyclical time. The banjoist's body does all four, and fights the instrument for the privilege.
VII. The Algorithm Is the Body
This is the essay's claim, and the book's: the algorithm is not in the software. The algorithm is in the body.
The tihai is an algorithm—a computational procedure for landing on sam. The session circle's self-regulation is an algorithm—a distributed protocol for maintaining the organism without central control. The classical guitar's technique is an algorithm—a set of procedures optimized over centuries for navigating specific repertoire. The banjo has two: the clawhammer roll is an algorithm—a perpetual motion pattern that braids rhythm, harmony, and melody into a single continuous downstroke stream. And the Scruggs roll is a different algorithm—three fingers computing their way through five strings, the permutations generating patterns that are as mathematically precise as the tihai's three repetitions resolving on sam.
None of these algorithms are written down in the way a computer program is written down. They are embodied—stored in the musculature, in the proprioceptive memory, in the body's feel for time and space and the relationship between intention and sound. They are transmitted not through notation but through proximity, through the guru-shishya tradition, through the session circle, through the years of sitting next to someone who plays and letting your body absorb their patterns.
Tversky's argument from Essay 7: spatial cognition is the foundation of all thinking. The body moving through space is the body thinking. Extend this to music: the body moving through time is the body computing. The tihai is a computation performed by the body. The session circle's self-regulation is a distributed computation performed by multiple bodies. The classical guitarist navigating Recuerdos is a spatial computation—the left hand traversing a geography of frets the way a walker traverses a geography of rooms.
The banjo, fighting for every note, is the computation at its most visible—the body working out in real time what the algorithm should be, because no one has written it yet. The frontier where the algorithm is being invented rather than executed. This is what Pikelny and I were doing with the Bach partitas: not just playing the music but engineering the algorithm for playing it on an instrument that doesn't know it exists.
When I opened that coffin case at eight years old and the century-old air hit my face, I did not know I was beginning a life of algorithmic invention. I did not know that Tom Dooley was the first entry in a database of murder ballads that would become a generative card game. I did not know that the gleaming Paramount inside the rotting case was going to lead me to ashrams in India and conservatory practice rooms and the back room of the Baggot Inn.
The instrument woke up. And it has been computing ever since.
