I started listening to Lo-Fi to figure out if there's any causation behind that
correlation. I tried to teach an AI to generate the ideal study music.
I feel like you could listen to it if the volume was at like one,
and then you walked away and you listened to different music.
Please don't release it.
Let me explain. Thank you to The Great Courses Plus for sponsoring this video.
When it comes down to focus, I have two modes.
I either start a task, blink, and suddenly it's six hours later and
I skip two meals, or I surround myself with a controlled level of distraction.
many different audio playing What are you doing? I'm focusing.
That was until I found lo-fi hip-hop chill beats to study/relax to sparkle emoji.
The titles are a bit much, but you know what? I'm talking about,
this girl. Anyway, I started listening to it back in 2018 and I saw my GPA just explosion
sound] and sure, there are several reasons as to why that could have happened,
but Lo-Fi music definitely makes me feel like I'm better at focusing.
Not every song, some slap a little too hard and pull me right out of the zone,
but there is a sweet spot.
So today in this video, you and I are going to figure out why Lo-Fi
Hip Hop might help you focus.
And if we can teach an AI to generate the perfect mix.
So I started my research by looking into the history of Lo-Fi Hip hop.
After that, I got a bit more familiar with other experiments people have done with
machine learning to generate new music, and I've got two big takeaways from my
initial readings. The first has to do with the structure of Lo-Fi Hip Hop.
Its iconic sound is composed of three parts.
The first, a jazzy instrumental, the second,
a drum beat combo of bass and snares called Boom BAP.
It's played intentionally off kilter in a style pioneered by the producer and rapper J
Dilla. And finally, intentional environmental noise that leans even further into the
imperfections that define the genre.
It usually plays at around 70 to 95 beats per minute and falls within this range of
frequencies. And that gives me a few key characteristics to look into when trying to
figure out why Lo-Fi can help people focus, but it also leads to a second thing.
It's an ingredient list and recipe for the things I need to teach my machine.
Here's the plan. Okay, here's how I'm gonna make music with a
machine. Step one I need a bunch of instrumental and drum midis.
These are basically files that contain information about the note that's played, how
long it's played, a bunch of other stuff.
I don't know much about it.
I'm an amateur. Step two.
I'm gonna sacrifice it to the machine. I'm going to be using an LSTM.
So basically you have a sequence of notes. And then the next step in the sequence you
tell the machine, "hey, get really good at guessing what the next
step is going to be," and then it gets really good at it.
Finally, I'm going to smash that drum and instrumental track together with some ambient
music, and I put two step twos.
This is step three. And then profit.
Sounds easy right? It was not easy.
I spent the next week swinging between wanting to throw my computer out a window and
wanting to throw myself out a window.
Oh my God. Oh, jeez. Oh my God.
Oh, Jesus. So it's been like three days.
My code has run fully without error for the first time.
So as long as there's any sound, I'm gonna be happy.
Okay, let's just play this.
I'm not happy. Okay, let's fix this.
Okay, so I think I've stopped it from just repeating the same note.
Basically, we get caught up in this loop where it was just like "the last note was a
C. The next note probably going to be a C," but then if it thinks that the if the last
note C, then the next, it just gets caught up in this loop.
Instead it has like this short list of likely next notes.
And then it randomly samples from that short list.
Anyway, here's how it sounds. Janky out of tune single notes
That hurt my forehead.
Isn't al.
All right? That was headed to a dark place, so I'm going on a walk to calm down.
I'm also going to do a bit of reading as to why,
like, those specific characteristics of Lo-Fi music might help with studying and focus.
I'm also going to collect a bit of environmental noise for the final track.
The more I read, the more I realized that the characteristics that make lo fi,
lo fi, that steady drumbeat, that frequency range,
that faux vinyl crackle, all those things work together to create a
sonic environment tuned for focus.
It's really interesting. I should warn you that music's impact on your mind isn't
universal. It depends on the task at hand and the type of person you are.
So if what you're doing requires a lot of thinking,
or you're currently in a place where you're going to get easily distracted, you should
probably hit mute. We have a limited capacity for attention,
and music uses up some of that essential resource.
In reality, if you want to focus, silence is almost always the better option.
However, background music can provide two key benefits.
So here's how Lo-Fi can help you focus.
First, it can block out more intrusive noises by forming an aural cocoon that tunes out or
reduces distractions, by anchoring them to a predictable rhythm.
Second, it can serve as a stimulant.
Songs that vibe in the fine line between putting you to sleep and popping off can
improve your productivity without being too distracting.
And that is where Lo-Fi Hip Hop comes in.
The jazzy instrumentals and drum loops are refreshing and fun,
but slow and repetitive enough that they become subconsciously predictable.
In addition, the dampened frequencies and environmental noise act as a blanket that
blends the music together and pushes it into the background using spatialization.
This makes the music sound less like a recording,
playing directly in your ears, and more like something in a physical space.
Finally, the genre's obsession with comfortable,
nostalgic elements like vinyl crackle in rainy days can help bring listeners peace and
improve their mood. All of this combines to make certain lo fi hip hop tracks easy to
process and ideal for focus.
And with all of that in mind, I now think that I know which parts of lo fi
I should lean into while making new tracks and which ones I should avoid.
Now I just need to get the steaming pile of garbage I call my code to actually function.
Let's do this. It took another two days and just endless emotional turmoil,
but I eventually was ready for my album release.
This might have been a bad idea.
Do you all know why you're here?
I have no idea what I'm doing here.
Apparently, this is the listening party.
Before we get to the songs, I do have a question for you guys.
Okay. You know me pretty well.
On a scale of 1 to 10, how musical do you think I am?
Like a three.
Which one's bad?
Zero.
On a scale of 1 to 10.
Zero.
You didn't know who Alicia Keys was?
I was just gonna bring that up.
So I would like to present to you the music.
Which track would you guys like to listen to?
The worst one.
Yeah. Let's work our way up.
This is an anxiety machine.
This sounds like, Now, I'm not going to compare it to any music.
That would be a disrespect to music.
So you're telling me that isn't the lo fi hip hop beat to chill and relax to?
A little far from that.
The next one. Are you ready?
Which one would you like?
Wait. Maybe this is the worst one.
Okay.
Okay. Wait for this drop.
There is no drop.
No. Is this gonna be available in our newsletter?
It will be.
Where can I subscribe to the newsletter?
Sabrina.
You can go to answerinprogress.com/newsletter.
To sign up. All right. Let's go with the only good track.
So to set the expectations this is the best I was able to do.
Okay.
I'm nervous again actually.
Yeah that waveform is really aggressive. music of mostly kicks and occasional piano notes
Kind of minecrafty. music continues
Very elevator music. Like I'm waiting for my floor just past the seventh floor.
Yeah.
Now we're at the 24th floor.
That was really funny.
Damn, that elevator's real fast.
I'm gonna close my eyes.
It's getting creepier. I think the more that I listen to it,
I'm like, I should not listen to this anymore.
It's unsettling.
It is slightly unsettling.
However, you know, it's just like, I don't know if it's a chill,
lo fi beat, but from listening to this, compared to the first lo fi beat singular
that you created, this is this is a lot.
This is a lot of improvement here.
Here's what it sounds like. If I just use like an actual drum loop designed by a human
being.
This one's good. The big question, Taha, could you study to this?
I would definitely study to this.
I feel like I have studied to this.
How do you guys think I did?
I think you did Badly.
[Laughs]
I think that the drum loop that you got did a lot of the heavy lifting here.
Melissa?
[Laughs]
Damn, dude. Speechless.
In fairness, it's it's pretty impressive that you got,
like, some semblance of, like, vibes.
Yeah. We've created a new genre of music beats to be anxious to.
To beats to be anxious to.
Okay, so while that wasn't the hardest video I've ever had to make,
I definitely felt like I bit off more than I could chew.
Way more than once. It was the first time in a while that I truly didn't know how to even
start. Every step I just felt out of my element and I felt like there was just so
much more I needed to learn.
But even though it took way longer than expected,
it was really nice to go from this.
To this.
This one's good.
Knowing all of the hard work that went behind it,
and by the end, we were able to figure out why lofi hip hop and ambient music can help
you study and also make a few decent beats of our own.
Kind of. Okay, I'll admit it was far from perfect,
but if we gave up because our first attempt or our first dozen attempts weren't perfect,
we wouldn't get very far.
You know, that's just a lesson in lo fi and in life.
I know that was a bad one, bye.
Hey there, I hope you liked that video.

Another way is to stick around as I thank the Great Courses Plus for sponsoring this video
while I turn myself into a lo fi hip hop girl.
So I found that learning things gets a lot harder after you leave,
like the guided learning environment of university.
And unfortunately I don't have the time or money to head back.
