An Untouched Instrument: The Theramin Explained
Have you ever seen an instrument that makes music without being touched? In today's episode, Hank introduces you to the theremin- a device that turns your body into part of a capacitor, and allows you to play music without touching anything! Learn all about this fascinating instrument in this new episode of SciShow!
Special thanks to Jay Bruns of nojayart.com for lending us his theremin, and Mike Emmons for setting up our meeting.

“I bought a piano but I never touch it” - “what a waste of money!” I bought a theremin but I never touch it” - “great!”
Hence the famous music quiz show quesion: "Do you strike, pluck, or blow a theremin?" "No."

It is worth noting that you also need an inductor in combination with the capacitor in order create the oscillations. Although you didn't mention it by name, you did show an inductor in the diagram at 1:25.

+Robert Armstrong If you just had a capacitor by itself the current would flow from one end to another and neutralize itself. In other words it would decay. The inductor allows the current to induce a electric field, which is changing, and that induces an opposite current in the inductor. Which means the current is now flowing the opposite way and recharges the capacitor. This keeps happening which is the oscillation.

absojake Why does the coil shape induce an electric field?
@dennisdavis6943

+Robert Armstrong the inductor resists change in current and stores energy in its magnetic field which is produced by current flowing through it. When the capacitor is fully charged there is no current in the wire, therefore no magnetic field on the incductor. but the charge wants to equalize with the other plate of the capacitor so the current starts to flow through the wire, through the inductor, and towards the other plate, this current produces a magnetic field in the inductor. once the charge on both plates is equal the current no longer wants to flow, but the inductor has stored up energy in its magnetic field and it wants to resist the current from stopping. this magnetic energy is what forces the current to continue flowing until the capacitor is fully charged again but in the opposite direction, and again the current has stopped and the inductor no longer has a magnetic field. then this process repeats over and over causing oscillation. without the inductor the charge would equalize on the capacitor and nothing would happen. i hope that made sense.

I received my Theremin yesterday and it has already changed my life. I'm a lifelong musician and the ability to detach myself from touching the instrument is amazing. Keyboards, stringed instruments and others which require manipulation of knobs are limiting unless you are a specialist. The Theremin, by its non-contact nature, enables one to express one's inner self with small movements of the hands. It's an ideal instrument for contemplation and expressing one's soul.
Wow! Nice explanation! I play the theremin for 10 years now, and I still love it!

You, sir, are amazing. I have to say I didn't expect much from a four-minute video on this subject. But I follow your Crash Course videos, so when I saw you in this vid, I knew I wouldn't be disappointed. Explaining not only capacitance, but heterodyning in under 4 minutes? That's what I came here for. Well done, sir. Also, you remind me of a very young Tom Lehrer.
I didn't even know I wanted to know about this. I love this channel.
This is genius. I've listened to these; love the sound.
Best description of how a theremin works that I've seen... Thanks! 🤗
You explained in seconds how an alternating current works better than my Physics teacher has all year. Thank you so much!
I find that interesting that this was posted on the exact day I added a Theremin to an EDM song that I'm working on! ^_^ How serendipitous!
Every time I hear those things I feel like I'm at the dentist lol
Hank, your face at the end of the video: gorgeous! Just perfect. Thanks for making another wonderful video. Now I know what a Theremin is! Yay!
Darn! Just saw someone who did a wonderfully complex rendition of Long and Winding Road, and the muscle memory to play tones on that instrument so expertly is really impressive. Thanks for having this on why it works. Love SciShow -- understandable answers to very specific questions! Off to listen to some more theremin music.

When I want to know something new .. SciShow and Hank come to the rescue. I've known about the theremin, but suddenly realised I thought it was magic. KZread recommendations and there you have it. Thank you so much!!
They missed out on a perfect opportunity to play the theme of SciShow with the theremin.
No mention of the Beach Boys!!!??? Gasp!
I did a class presentation on the theremin about 7 years ago and I've been in love with the instrument ever since! I own a lot of Clara Rockmore's theremin covers, what a virtuoso!! Someday I hope to at least try one out for myself or even own one!
It's interesting the theremin featured here is a Moog theremin... as in the Moog synthesizer (same manufacturer). Robert Moog sold these to help pay for the research on his synthesizer long ago, and his company continues to sell them today. The Moog synthesizer paved the way for the various electronic keyboard instruments we use today.

Oh my god, I always loved the idea of the theremin! There's one a the Science Center here. Like always, awesome video!
I'm picking up good vibrations watching this.
The *charge* doesn't change with distance, though the *capacitance* definitely does. C = eA/d; d changes when you move your hand back and forth (A can too if you turn your hand relative to the antenna, though this is a relatively small effect given the effective aperture of the antenna). The real effect though, is on the resonant frequency of the LC tank (MOST theremins include this); one portion of the C being the capacitor formed by the player's hand and the antenna. The resonant frequency of the tank is: f = 1/ (2*pi*sqrt(LC)). In theremin design there is typically a relatively large discrete resonant capacitor (100 to 1000 pF), which the player/antenna capacitor is in parallel with. The hand to antenna capacitance is tiny in comparison, maxing out at only a few pF. But that's enough! The other elements in the circuit are fixed, and a few pF of difference causes a detectable change in the resonant frequency, and thus the variations in pitch and volume which turn a simple circuit into an instrument. :-)

I'll admit, I'm not trained on the thing and couldn't accurately perform a song with it, I mainly use it for sound effects in the recording studio, but coming from a cello background I found that it was more intuitive to control pitch with my left hand and volume with my right. It's one of the Moog Etherwave kits, so I may open it up again and try to reverse the whole thing.
