The Teacher's Student

Seven years after Johann Sebastian Bach died, one of his former students published a curious little book. Its title was characteristically German in its precision: Der allezeit fertige Menuetten- und Polonaisencomponist — "The Ever-Ready Minuet and Polonaise Composer."

Kirnberger had studied with Bach in Leipzig from 1739 to 1741. Then he'd disappeared into Poland for a decade, working for various noblemen, collecting folk dances, trying to make sense of what the old man had taught him. By 1758 he'd landed a position with Princess Anna Amalia of Prussia in Berlin, where he'd stay until his death.

Those who knew him described Kirnberger as "recalcitrant" — difficult, stubborn. His theoretical writings were so disorganized he needed help editing them. But he was fiercely devoted to his students, and even more devoted to preserving Bach's legacy. He spent years trying to get Bach's chorale settings published. He founded a library that still holds Bach manuscripts today.

The dice game wasn't entertainment separate from serious music. It was the same principle — modular construction within harmonic constraints — made explicit. Made playable. Bach's Art of Fugue takes one subject and generates fourteen fugues and four canons from it. Kirnberger's dice game takes 192 bars and generates countless minuets.

He admitted the idea wasn't entirely his. "I took it, imperfect, from others," he wrote, possibly thinking of Athanasius Kircher's "composing machine" from a century before. But Kirnberger was the first to publish it. The first to put dice in composers' hands and say: here, try it yourself.

He deliberately scrambled the bar numbers and created lookup tables. Why? "To disguise the inner workings." Even in a parlour game, he wanted the magic to stay magical.

The Son

One year after Kirnberger's game appeared, Bach's second surviving son published his own version. Its title was pointed: Einfall, einen doppelten Contrapunct in der Octave von sechs Tacten zu machen, ohne die Regeln davon zu wissen — "A method for making six bars of double counterpoint at the octave without knowing the rules."

Where Kirnberger gave the world dances, C.P.E. Bach gave them counterpoint. Where Kirnberger aimed at parlour entertainment, the son aimed at something more intellectual. Only six bars. But proper counterpoint. The kind his father had drilled into him.

C.P.E. Bach and Kirnberger were both part of Princess Anna Amalia's Berlin circle. They knew each other. They worked together, eventually, on editing Bach senior's chorale settings. The son and the student, both trying to preserve what the master had left behind.

But they approached it differently. Kirnberger was the theorist, trying to systematize Bach's methods into rules. C.P.E. was the practitioner, the keyboard virtuoso, the one who'd actually sat beside his father and learned by doing.

His dice game was a small thing — barely a parlour trick compared to Kirnberger's elaborate system. But it made a point. Even counterpoint, that most rule-bound of musical forms, could emerge from chance operations. The rules were in the bars themselves, pre-composed. The randomness just selected between them.

The Genius at Play

Thirty years later, in a city that adored him, Mozart scribbled something curious on a manuscript page. The same page held sketches for his G minor String Quintet — serious work, profound work. But squeezed around the edges: 176 one-bar fragments with letters of the alphabet assigned to them.

It was a game. Spell out a name — any name — and the letters would select bars that, strung together, made music.

He was in Prague to premiere Don Giovanni, an opera about a libertine dragged to hell. The city had gone mad for Figaro the year before. "Here they talk of nothing but Figaro," Mozart wrote to his friend Gottfried von Jacquin. "Nothing is played, sung or whistled but Figaro. No opera draws like Figaro. Nothing, nothing but Figaro."

Between rehearsals and concerts and the small matter of finishing an opera, Mozart played games. On the journey to Prague, he and his friends had invented silly nicknames for each other. He loved billiards, coffee, tobacco. He wrote letters to his cousin full of scatological wordplay that still makes scholars blush.

And somewhere in there, probably for his piano student Francisca von Jacquin, he made a dice game. The selected bars on his manuscript spell out "fanciS" — Francisca, more or less.

The game wasn't published until after his death, when his publisher Simrock saw a commercial opportunity. By then Mozart was gone, dead at 35, leaving an unfinished Requiem and a parlour game that would bear his name for centuries.

Whether he knew about Kirnberger's game, or his friend C.P.E. Bach's, we can't say for certain. The principle was in the air. Multiple composers published their own versions throughout the late 18th century. But Mozart's became the famous one. The one people still play today.

Play It Yourself

Roll the dice, look up the bars, play what you've composed. Every result is different. Every evening generates music that might never exist again.

Commercial recordings are rare — these weren't meant to be performed. They were meant to be played. You roll dice, get a unique piece, play it on keyboard in a salon. Every performance different. Every roll generates something that probably never existed before and may never exist again.

The same principle. The same productive constraint. The same gap where the music lives.

The Modulation Pattern

After listening to the Complete Mozart Edition recording, I found myself with a question: how long has the concept of modulation existed? The answer led somewhere unexpected.

The Core Discovery

Once you see modulation as "information riding on carriers," it appears everywhere:

Why It Works

The principle persists because it isn't arbitrary. It's how meaning gets encoded when consciousness can only process so much at once. The carrier provides stability — parseable, predictable structure. The modulation provides meaning — small variations that encode information. The balance between them is where art lives.

Mozart's dice game works because the harmonic framework is the carrier. Every bar in position 1 leads correctly to position 2. The dice just select which melodic path. All paths work harmonically. The variety is constrained by structure.

The Greeks Had It First

I'd assumed modulation was a Latin invention — modulari, to measure rhythmically. But the Greeks had it first. They called it metabole (μεταβολή).

Aristoxenus, writing around 320 BCE, explicitly theorized about modulation. His work addressed "pitch, intervals, genera, systems, modes, and modulation as they applied to melody." The Greeks built two systems around the concept:

The Romans translated metabole into modulatio, which became our modulation. But the insight is older than Rome.

Even more striking: the Greek word for prosody — the musical qualities of speech — is prosodia, meaning "sung to music." They understood that speech itself is music, that the pitch and rhythm of our voices encode emotion the way melody encodes feeling.

AI Music Today

The parallels between 1787 and 2024 are uncanny.

And the user responses echo across centuries. One Suno user in 2024: "It feels like it's unlocked something in me that was laying dormant all these years because I never connected with an instrument."

That's the same sentiment that made dice games "practically guaranteed popularity among the galant middle class" in 1787.

The difference is scale. Mozart's game had 759 billion possibilities. Suno's model has effectively infinite. But the principle — modular combination within learned constraints — is unchanged.
