Hey I'm Jake and toknight we're doing something a little different.
So, before we begin pour yourself a nice big cup of coffee or caffeinated beverage of choice
because we're about to be APP ALL KNIGHT.
If you follow Michael on twitter you might have seen him use a Theremin
He's actually playing it
When you play the theremin, one of your hands controls pitch and the other controls volume.
Without touching anything, your hands modulate how much charge is dumped by the instruments capacitors.
A capacitor stores potential energy in an electric field by using two conductive plates
separated by air or any other non-conductive material.
Each of a theremin's antenna only have one of needed plates so guess where the others are?
That's right, your hands!
Changing how near or far your hands are from each antenna changes the
respective capacitor's charges and thus, the sound.
The theremin was invented by Leon Theremin in 1920.
He originally called it an "Etherphone," but eventually it was given his name instead.
It gained a lot of popularity after being used in a ton of science fiction movies
And also in the Beach Boys song Good Vibrations that goes like: oooeeooooo
The concept of electrical impulses used
to create pitch eventually led to the synthesizers we know and love today.
So in this episode we're going to be focusing on theremins
But all these apps are for iPhone. We will link to ones down there for android
as well
Let's start with a simple one: Theremin Pro.
This app doesn't actually simulate the playing a theremin, but it gives a very
intuitive way of recreating the sounds.
Up and down changes the volume, and left and right changes the pitch.
Easy right?
Maybe a little too easy.
Let's go into another one that takes it to the max with Therimax
Theremax can use both the touch screen and your front facing camera.
This app is nice because it actually shows the name of the notes you're playing as
you play them.
That is pure romance right there.
Speaking of which, I know I say this a lot, but I really do appreciate you.
It must be your magnetic personality, but how can you tell if something will be attracted
to a magnet?
Well, you need a magnet.
Let's go find one- oh wait, there's one in the phone right now!
Up in the top right corner of an iphone and in the center for android phones, is the Magnetometer.
A magnetometer is a specially designed electromagnet that is usually used in electronic compasses
to read the earth's magnetic field.
That's all really interesting, but can we make music with it?
This app, just called, well, Theremin, uses all the sensors in your phone to do just that.
Turning on one of the three axes for each of these sensors will allow you to tilt, shake,
and magnetize to make crazy soundscapes.
Going back to the magnetometer, you can use both magnets and magnetic metals
You can use anything from a hairclip to a fridge magnet, which I have right here
(oohs and ahhs)
Isn't that wild? And it is more accurate to what a theremin is actually like, which creates its own electromagnetic
That you then disrupt with your hand.
The other sensors will change the pitch in different ways.
The accelerometer will change tones depending on which way you tilt your phone, and the
gyroscope will change depending on the speed that the phone is moving.
You can use the x and y axes on the touch screen itself to add even more sounds.
Let's see what it all sounds like together.
Oh let me get out my magnet, one second
Oh, that's like the new Drake song. Gonna be the smash hit of the summer. How do I stop this?
Now we get to our final Theremin app. This one's actually my favorite,
but it does cost money so the other free ones are good choices
This one (which is also called theremin) uses your phones flashlight rather
than magnetics.
The app uses the camera to measure the light reflected off your hand to change the note.
What's fun about this one is that if you cover up the flashlight you can point it at
other light sources to change the pitch.
Like the wall, or the sun, or even THIS VIDEO you sneaky little DONGer
This one's a bit more musical than the others, as you can set it to "autotune" to a certain
scale which you can customize.
You can also change the sounds and effects to create something a little more fun than
just a bunch of bleeps and bloops like some kinda robot.
Let me give you a quick little example
Woah
But then you can do other things like up the vibrato.
Pretty neat. The harmony can change. Let's bring it up a few octaves. Oh, maybe I'll bring it down a few octaves.
Oh that does sound spooky.
Before you begin Theremining around and sharing your wonderful compositions with the world
I would highly recommend one more app, which is the sponsor of this episode: Audible
You've probably heard of Audible, they have a giant, massive library of audiobooks
And one that I really liked recently called The Terror
And the Terror is a very interesting book. It's a historical fiction book
About the expedition in 1845 of the HMS Erebus and the HMS Terror
That went to discover the northwest passage
And as you might know they never made it, they never came back
That was the last time anyone heard of them
So this book is about what happened. Obviously it's a fictional telling, we don't really know
But it's from the perspective of the crew and the captains about what actually went down
In the ice and the snow, but there's a twist.
And that is that there's a monster tracking them down. It's really really cool.
And actually what I think is most interesting is the fact that
we didn't even find the ships until about 160 years later
That's when we discovered where they actually were.
It's really cool there's cannibalism all this fun stuff. It's an incredible book
and if you sign up using the link in the description below, audible.com/appallknight
you'll get one free audiobook with a 30-day trial.
So I would highly recommend The Terror if you want and you can also text the url or appallknight
to 500-500. Again that's Audible.com/appallknight
Again that's audible.com/appallknight one free audiobook and a 30 day trial.
The Terror is really fantastic. It's kinda graphic there's a lot of violence, so I'd recommend keeping that in mind.
Ok I hope you enjoy Theremins, I hope you enjoy Audible
and I enjoy spending this time with you. And that face. Ah what a face.
Let's just, let's just look at that face. Imagine that I'm gonna be a Theremin.
Weeeeooooooo. That's the sound that happens when I look at you. And as always
Thanks for watching.
