A 4-Track Mind

Hey, it's Latif. We've got an oldie but a goodie today from 2011, this episode. And I mean, I can say this because I had nothing to do with making it. It pulls off one of the most difficult and satisfying things a story, really a story in any medium, can do, which is that it stretches your conception of what a human being is capable of. And besides being just a jaw-dropping portrait of a human with a brain. It also just makes you wonder what obscure superpowers we are all just walking around with, totally oblivious that they are even superpowers anyway? If you haven't heard it before, I'm jealous of you.

Alright, okay.

Alright.

You're listening to Radiolab, Radiolab from.

Wnyc see yep.

Rewind.

No, it won't be so bad. Should we do that now? Yep, hey, I'm Jad Abumrad. This is Radiolab.

And painful. Just thinking about this story makes my head hurt.

That's Jessica Benko, she's a reporter, yep, and she's the one who initially told me the story.

So a little while ago, I went up to visit this guy. Hi Bob, Milne Bob, it's nice to see you. nice to see you.

And who is he?

He's an amazing piano player.

Really.

He's had this special relationship with music ever since he was a boy. Did you grow up with any other instruments inside the house other than the piano, or was that what you started out on?

Well, my mother made me take piano lessons, and I hated it. I didn't like the sound of minor keys, and the piano teachers had me playing a recital in which there was a Schubert minor key piece in it.

These days, though, his main music isn't so much Schubert, it's actually ragtime.

One, two, three, four, one, two, three, four, the rhythms.

So the thing about ragtime is that oftentimes the player is actually playing two different rhythms at the same time one with the left hand, one with the right hand.

And then he puts the rhythms of three in the right hand.

The thing about Bob is he can do this like times. A thousand, oh.

What does that even mean?

Well, let me back up. I first heard about Bob from a neurologist named Kirsten Betterman, who is now at Penn State University.

The first time I heard about Bob Milne was through friends.

Kirsten heard about Bob from a colleague who'd seen him play for an audience.

Well, I might just take a tune like a.

He was actually playing multiple rhythms with his two different hands, and switching back and forth between different pieces of music and carrying on a conversation at the same time.

Well, let's say he's not too good at singing.

You can look up videos of Bob on YouTube and you can see him performing and throwing out jokes. But at times, you'll see him carry on a full conversation while playing. From the perspective of a neurologist, this is actually really hard. Because the part of your brain that should be engaged in playing a piece of music that complicated should also be engaged in having a conversation.

The talking part and the playing part are the same part.

They're the same part in most of us. For most people, that sort of thing playing a complex piece of music and having a conversation would interfere with one another.

Yes, that's what you usually would think, unless you're highly skilled and you play maybe one piece of music at a time that you've done multiple times. But even then, it would be very difficult to this degree.

So Kirsten got in touch with Bob and she started asking him some questions.

About the way you would perceive music.

And in the course of chatting with him and talking about how he perceives music and all of this, he happened to say to her.

That I could hear an entire symphony in my head. And I didn't think that was too big a deal because I always listened to two of them at once.

He told her.

I only have to focus on the one mentally that I want to hear at a given time, and then that's the piece I play. But I hear them all ongoing.

Did he just say he can hear two?

Two different symphonies.

In his head.

At the same time.

And we thought this was very unusual.

Yeah, but I mean, are we talking the full symphonies or just the melodies?

Every instrument.

Every instrument.

And he can focus in and.

Turn one of them up, one of them down, and they both run simultaneously. So then she pushed to the envelope and asked me if I can hear three.

Three pieces of music.

I said, Well, I don't know, never tried.

But he was like, Yeah, I think I could do three.

When we challenged him a little bit, actually, he said, I can do four if you ask me what?

But I wouldn't go any further than that.

No, that's total just four symphonies at the same time.

Absolute Cacophony.

You know the four pieces of music that just wow, I said, nobody can do this. It was really critical.

Yeah, because it's not true.

We had to think about how to test this.

Let me tell you about how the experiment worked, and then tell me if you think it's true.

All right.

We came up with the behavioral test.

So the first thing Kirsten had to do was find a control someone to compare Bob to, right, so she found a conductor.

Peter Perry, who's the former conductor of the Winston-Salem Symphony?

Who is himself an accomplished musician? Before the test, she sent him and Bob four pieces of music.

We had the Schubert Symphony.

And, finally, one from Mendelssohn.

Very different in their themes and instrumentations, and the challenge for them was to learn these four pieces of music.

Completely memorize them four different tunes, and they only gave me a couple days to listen to them.

And then play them in their mind, and we would then ask them where in a certain piece they would be after an arbitrary time.

I'm not really following what they do.

Okay, so here's what they did. They put these guys in the scanner and they said to them, I want you to play the music in your mind.

Play the music in your mind.

Close your eyes and imagine the music.

So no music is playing out loud.

No music playing, just inside their head.

And are they imagining it however they want?

No, no, exactly what they had heard on the CD.

So same instruments coming in and out, yep, same tempo, yep, so if it was vivace on the CD, vivace in their head.

Exactly.

And why were they doing this again?

Well, they wanted to see if these guys could track via memory these really complicated pieces of music I see. So they put the guys in the scanner and they're laying there and on a screen in front of them. The word start flashes, and at that moment, they start playing the first piece of music back in their head.

The researchers, Yeah, oh so, while Bob and this dude are imagining it, they're actually keeping track of where the real CD is.

Exactly.

Like the note.

The exact phrase.

And.

So our conductor, our control, was able to listen to one piece of music at a time. And was really right on target, with the right answer and timing within a second.

Wow, so this conductor's imagined symphony was only a second off from the real one.

Yep, same with Bob, so Bob's within a note or two.

Not bad.

Now round two.

The multi-song task, as we called it.

They told them both to start that first piece of music again.

Simultaneously.

Yep.

All right, I'm already like, come on, it's crazy like this is, we've slipped into fantasy.

Well, and that's what happened for the conductor, he couldn't do it.

He couldn't do two simultaneously.

Yeah, of course he couldn't do it. It's impossible.

There was no chance, he said. This is an overwhelming impossible task.

His brain just shut down.

What, like he died or something?

He stopped even being able to track the first piece of music. He just got confused. Now we go to Bob.

They put me into the MRI and they asked me, Start tune one in your head, so I did.

Tell us where are you?

Where are you in Tune One, Beethoven's Symphony right now? What do you hear? So I told her and I described how I felt, what the piece was playing at that point, and the same thing with Tune two.

Jess, you're telling me something that's just not.

Kirsten's really, you know, she's got a lot of integrity.

Just my common sense right now is yelling like a three-year-old.

It really is mind-boggling to think about. It makes my brain hurt.

But, you know, we proved, yeah, you can do it.

When Kirsten gave you the different pieces of music to listen to, did any of them clash?

No.

All right, so assuming this is true, how does he do this? how does he explain to himself how he does this?

So I think there's two things going on here, the first has to do with emotion.

Emotion.

Bob is using different brain areas, I think in his case, probably more emotional brain center.

You know, emotion deepens the way that we experience things, makes stronger memories, and Bob has a really strong emotional relationship with music.

Well, don't we all?

Yeah, but it's a little bit beyond the whole. Minor keys make me feel sad. He has really specific emotions associated with individual keys on the scale.

When I hear C major, it's a very bland key, it's like, I don't know how to describe, It's like eating water, soup or something like that. But D Major is a bright key. That makes me want to dance, even though I can't dance. And every key, every one of the keys of the piano, had a different emotional attachment to me.

So for Bob, if just the keys are triggering different emotions, imagine what it must be like when you get to actual music.

So you think that something about how he experiences the emotions of the music makes it etch more deeply in his brain or something?

Yeah, I think he's when he's got these four pieces of music going, he's not thinking hard about tracking each one of them. He's already in them. He feels them inside his body, and you can feel more with them, one feeling at a time.

These goals can start to slip when schedules get packed and the mind gets cloudy with stress. But when you're starting to feel overwhelmed, a non-negotiable like therapy is more important than ever. Therapy can help you keep your cup full by giving you the tools you need to get back into balance.

Kamala Harris's current office at the White House is just a few miles away from where she spent some formative political years. Howard University is one of America's most well-known historically Black colleges and could soon become the first HBCU to produce a U.S president on Chi-rite. Stroll the yard with me as we walk through Harris's time at Howard and consider how it shaped her as a candidate. On the next, Notes from America.

The second idea has to do actually more with image and space, really.

I can picture two symphony orchestras sitting side by side.

He actually sees the literal orchestras in his head.

Yeah, and I see them as silhouettes. There's no conductor in front of either one. There's a brownish hue out in front of them, like it's the floor. That's more the color of the deep brown of a violin, and in back of them, there's a semi-circle that's bluish in color.

Wow, wow.

So his crazy talents may have something to do with this movie-making thing that he does in his head.

Yeah, but it's not just a movie, it's like a 3D movie. He can use it to find out where a specific instrument is.

How do you mean?

In his mind's eye, he can fly out over these orchestras and actually look down on the individual instrument he wants to see.

And I'm looking down and I see the piano out in front of him.

He can zoom in and see them playing their instrument.

Okay, now I'm up there in the air listening to this thing, and over on my left side, I can still hear this. Brahms going along on Brahms. I can only see the silhouettes from the front, whereas the emperor over here. I can see full color in every person's face in it, plus hear the lines that they're playing.

And as he's flying out over these orchestras, the instruments actually get louder and softer, depending on where he is, like if he goes behind orchestra No 1..

I can hear the bass much louder. Let's see, yeah, then if I go over to the left side, I'm hearing the violins.

And he says he can float right above the players and actually see what they're doing.

I can see every wrinkle in the pleated shirts of their tuxedos.

God, listening to music for this guy must be like an acid trip, the way that he's describing it.

I think it is, and when he listens to recorded music, it's so much diminished from what he feels when he's imagining it.

So he doesn't listen to CDs.

He cannot stand listening to CDs.

Wow.

Yeah, he's a real example of the extremes of the human mind.

So what does he do with these crazy talents? I mean, is he like a billionaire?

Nope, first of all, ragtime's not exactly the most popular form of music in the United States at this point. But it's what he likes to play. And he plays, you know, 250 shows a year, but a lot of them are at historical societies or churches.

Linda and I. We've got a small motorhome. It's an airport bus, one of those little 15-passenger buses. It's got a hot shower and a bathroom and a bed, of course.

So, you know, he travels around in his little motorhome with his wife when he can, and without her when he can't, and sleeps in Walmart parking lots. He's working on an opera, which is mostly done, and he writes it in his head while he's driving. And then he sits down in a McDonald's and writes it out on paper. And, you know, that's pretty much what he does with his life.

Thanks to reporter Jess Benko for that great story and also to producer Mark Phillips for making it sound so good. But why should we share the information the way we just did?

Why not do the outro in a way that Bob Milne would fully and completely appreciate?

You mean, so, we should say it all together in a big jumble simultaneously? And he'll be able to think the JAD side and then the Roberts side. Okay, ready, yep.

One, two, three, four, one, two, three, four.

Thank you to all the people who play the piano, thank you to listeners of the piano, players who play the piano, thank you, of course, to tuners of those pianos, thank you to Walmart. And to discount cheap goods.

The left hand hitting the piano.

Thank you, Robert.

Good night, see you then.
