  • Hey i'm Jake and toknight we're doing something a little different.

  • But before we get into it pour yourself a nice big cup of coffee or caffeinated beverage

  • of your choice because we're about to 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 capacitor.

  • 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 the theremin's antenna only have one of the needed play 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

  • Charge 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.

  • the concept of electric impulses being used

  • to create pitch eventually led to the synthesizers we know and love today.

  • So in this episode we're gonna be focusing on theremins

  • All these apps are for iPhone. We'll link to ones down there that are on android as well

  • Let's start with a simple one: Theremin Pro.

  • This app doesn't actually simulate the playing of 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 take it to the max with Therimax

  • This one 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.

  • 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 right on your phone.

  • 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

  • to affect the pitch.

  • You can use anything from a hairclip to a fridge magnet, which I have right here!

  • And this is what happens when I turn on the magnetometer in this app.

  • (Theremin noises and oohs)

  • This is very similar to the way a real theremin works, which creates its own electromagnetic

  • field that you then disrupt with your hand.

  • The other sensors will change the pitch in different ways.

  • The gyroscope will change tones depending on which way you tilt your phone, and the

  • accelerometer will change depending on the speed that the phone is moving.

  • This app gets those two mixed up, but we'll forgive them because it's still pretty cool.

  • Let's see what it all sounds like together.

  • Oh, that's like the new drake song. It's gonna the smash hit of the summer. How do I stop this.

  • Now we come to our final theremin app. and this one's actually my favorite

  • but it does cost money, so these other free ones are good choices.

  • Now this one that 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 toautotuneto 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 just give you a quick little example.

  • woah

  • You can do other things like up the vibrato.

  • Pretty neat. The harmony can also change. Let's bring it up a few octaves. oh, let's bring it down a few octaves.

  • That sounds spooky,

  • Before you begin theremining around and sharing your wonderful compositions with the world

  • I would highly recommend one more app for you 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, really, liked recently is called The Terror.

  • And the Terror is a very interesting book. It's a historical fiction book about the expedition in 1845

  • of HMS Terror and HMS Erebus 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 that anyone heard of them.

  • And so this book is about what happened. Obviously it's a fictional telling because 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.

  • And 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.

  • And 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 getting the Terror if you want.

  • And you can text the URL or appall knight to 500-500

  • Again that's audible.com/appallknight for 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 would recommend keeping that in mind.

  • but it is really really good. Ok, I hope you enjoy theremins. I hope you enjoy Audible.

  • And I enjoy spending this time with you. And that face. Oh what a face. Let's just look at that face.

  • Let's just imagine that I'm gonna be a theremin: ooooooooooooo

  • That's the sound that happens when I look at you. And as always thanks for watching.

Hey i'm Jake and toknight we're doing something a little different.
