There Are No Wrong Notes—Only Bad Decisions

A game theory approach to improvisation, uncertainty, and thinking in real time

Most musicians are trained to avoid mistakes. Improvisers, whether they realize it or not, are trained to make decisions when there is no clear right answer—and no time to hesitate. That difference ends up meaning everything.

At a certain level, what’s being developed isn’t just musical skill—it’s adaptive intelligence: the ability to process incomplete information, act on it, and revise in real time.

Let’s explore this further.

The Game You’re Already Playing

In an earlier post, I talked about the sunk cost fallacy. Here’s another branch of microeconomics that lives a lot closer to the bandstand than most people realize: game theory. You could make a convincing argument that improvised music is just game theory with a rhythm section.

And no, you don’t need a degree in economics to understand it. Believe it or not, you’ve already been playing the game. Most people just don’t realize it.

At its core, game theory is simple. You’re making decisions that depend on other people’s decisions. Not just “What should I do?” but “What should I do, knowing someone else is also choosing—and might be wrong, late, inspired, or completely out of left field?”

Strip it down, and it’s this:

• multiple players;

• multiple choices;

• and one shared outcome nobody fully controls.

You see it everywhere. Two drivers merging into one lane—if both decide they’re the hero, now you’ve got tension. If one yields, things move. If both hesitate, you’ve built a traffic sculpture.

Or let’s look at it through a business lens:

two coffee shops on the same block. If both keep prices high, everybody eats. If one drops prices, they grab the crowd. If both drop prices, now they’re working harder for less money and calling it strategy so they can sleep at night.

Same structure. Different setting.

Now bring it to music. You have two improvisers—if both listen, the music breathes. If one decides it’s their TED Talk, the balance shifts. If both decide to testify at once, now you’ve got sonic congestion and nobody’s getting anywhere. Nobody announces their strategy. You either read it, or get run over by it.

That’s the game. And this is where a lot of musicians get it wrong.

Because once you see improvisation this way, you also have to admit something that doesn’t fit the usual narrative. Playing improvised music isn’t easier. It’s harder. Not technically harder, but cognitively harder. It demands real-time processing under pressure, where perception and action are fused and hesitation carries a cost.

And when people don’t recognize that, they don’t question themselves. They downgrade the music instead.

Discipline Without a Safety Net

There’s a persistent myth that people who play improvised music lack discipline—that they couldn’t “really play,” so they found a loophole where anything goes. It gets repeated enough that it starts to sound like common sense.

It isn’t.

More often, it comes from someone who has become very good at “playing the changes,” but has not had to make a musical decision without a blueprint in years—and somewhere along the way, they mistake predictability for control.

Because when you really shine the light on it, improvised music isn’t the absence of discipline. It’s discipline without insulation.

You have to play an entire set with no chord chart, no fixed form, and no agreement about where things are supposed to land. It’s just you, your ears, and the consequences—an unstructured, high-stakes decision environment.

In more conventional settings, the framework does a lot of the thinking for you. Harmony, form, style—they narrow the possibilities and protect you from yourself. Take that away, and the field opens up. The drummer drops the pulse, the pianist abandons harmony, the bass player stops behaving like a bass player.

Now you have to decide, how to decide, without knowing what’s coming next.

That’s not freedom. That’s exposure.

And exposure is where adaptive intelligence either shows up or it doesn’t.

Outcomes, Not Mistakes

Here’s another myth. Most inexperienced improvisers don’t freeze because they lack ideas. They freeze because they can’t sort them in time. That hesitation isn’t sensitivity, it’s cognitive overload.

Game theory strips the drama out of the word “mistake.” You make the best decision you can with what you hear, then you adjust. Because what we call mistakes are often just low-probability outcomes showing up uninvited, and refusing to leave.

So improvisation in this context is less about correctness and more about probabilistic thinking. You’re constantly assessing likelihoods like what might work, what might clash, and what might open something up. And acting before certainty arrives.

An experienced improviser doesn’t eliminate wrong notes. They make them unlikely—and when one shows up, they deal with it. A beginner hears a note and thinks, “I messed up.” An experienced improviser hears the same note and thinks, “Alright—now this is what we’re dealing with.” Same note. Different mind.

Let’s circle back to driving. Most of the time, traffic behaves. Sometimes it doesn’t. Occasionally, someone does something so illogical you start wondering how they passed anything resembling a test. You don’t stop the car and announce failure. You recalibrate.

Playing works the same way. Every note carries a certain amount of uncertainty, which means listening isn’t courtesy, it’s survival. If you don’t know what’s happening, you’re not shaping the moment. You’re reacting late and calling it intention.

I remember early gigs without any safety net. One of the first was with Dave Liebman at Cornelia Street Café, with Tony Moreno and Jim Black. There were no tunes, no count-offs, and no signal of what was coming. Liebman lifted his horn and started playing.

That was the signal.

The floor disappeared.

They were already fluent in this way of playing. I wasn’t. I was a former “young lion,” still shedding what was left of his fur. I felt like a kid grabbing onto a moving train, hoping something would make sense before it was gone. And that wasn’t about chops or needing to spend more time in the shed. It was about not knowing how to read what was happening.

So I filled space, reached for ideas, played what I thought might work.

In other words, I guessed.

And sometimes I guessed right—just enough to survive and think I understood what was going on.

But I’m happy to say that over time, that illusion fades. You stop guessing and start recognizing.

Experience, Recognition, and the Illusion of Instinct

Here’s the difference. Experience sharpens awareness. Not necessarily more vocabulary—but faster recognition. You’ve seen enough versions of the situation to anticipate what’s likely and what’s about to fall apart.

Where one player hears chaos, another hears structure. Not fixed structure, but emerging structure: patterns forming in real time.

What people call instinct is usually compressed experience. It’s simply cognition happening fast enough to feel like intuition.

“Feel” in this context isn’t mysterious.

It’s trained perception operating at speed.

What’s Left When the Script Is Gone

Improvised music often gets labeled as antisocial: musicians disappearing into their own worlds, each one chasing a private idea of freedom. From the outside, I understand the accusation. Because sometimes that is the case. However, from the inside, it misses the point.

Here’s something that might make some a little uncomfortable. Improvised music might be the most socially dependent form of jazz there is.

Because without a shared script, the intelligence is distributed across the group. No single player controls the outcome. Meaning emerges through interaction—through constant adjustment, response, and recalibration.

You act, they react, you recover in real time.

If you’re listening, it becomes a conversation nobody planned but still makes sense. If you’re not, it doesn’t drift. It collapses, and it exposes very quickly who was participating and who was just waiting to play.

Which is why the idea that this music is a loophole for people who can’t play has always sounded less like criticism and more like projection.

Improvised music is what’s left when the script is gone.

And when the script is gone, what’s left isn’t comfort.

It’s exposure.
