- The 2016 Flame Challenge asked the world's top scientists to answer a deceptively simple question: What is sound? In response, acoustician Whitney Coyle, who is also a trained musician, demonstrated key aspects of sound--timbre, pitch, harmonics--by playing various notes on a flute.

That didn't really answer it for me. Cool though
Each musical instrument is going to sound multiple frequencies at the same time - though one is the most prominent, and the rest are much more quiet. This different collection of sounds explains why a trumpet and violin playing the same note (same frequency) sound different - there is a different mix of frequencies, even if the prominent frequency is the same.
Harmonics refers to that collection of multiple frequencies observed - even without a musician changing fingerings, tube length, etc. Each observed pitch is called a harmonic. You can see each of these harmonics as she plays - looking at the highest three or four peaks in the graph.
As the flute player added extra energy by blowing harder/faster, she highlighted the higher frequencies of the harmonic series. Note that all of the same collection of frequencies are visible, though one of the frequencies becomes louder.
Hope this helps
@@michaelhafen Excellent Explanation
@@michaelhafen Michael, you’re the man! Thank You!
Me either but i like her thighs 😁

OMG 2 minutes to know everything you need to understand music!!! You opened my mind with this!! Thank you so much for this video! I wish I could had watched the whole video.
This is the best intuitive tutorial I have ever seen, uh my god, and I have seen a lot of them! Thank you thank you
Harmonics are integer multiples of a fundamental frequency. Overtones are (usually rational) multiples of a fundamental frequency. Harmonics are overtones, but overtones are not harmonics.
This sort of stuff is much better visualized with a spectrogram.
this is what I'm looking for
Nice
@1ucasb possibly you're saying the opposite. Overtones are harmonics,but harmonics aren't harmonics always. Please cross check what you've said. Thanks
But why do they happen
@@talhatanzil5138 but harmonics are a subgroup within overtones? So how can that be true
Video has wrong title. no explanation WHAT harmonics are.
Not here to understand harmonics in music but how harmonics work in submarine screws and why submarines have an odd number of screws so they do not have a harmonic signature. This helped.
I am at 5th week and the harmonics were introduced at the 1st week in college, I was confused until this video. Thank you so much.
Apply this to vision too. We're only seeing/ hearing one thing, and that is the result of many other factors we are not perceiving. Pretty crazy to think. What are we not seeing?
I'd like to watch the full video
Didn't answer the question
Are these harmonics the same as the ones studied in electric engineering?
In the sense that they are both a result of interlacing wave functions, yes.
Though in musical instruments it's mostly about standing waves, where you manipulate the length in various ways depending on the instrument, and the harmonics then comes from the various tones which will fit a discreet amout of wavelengths into that particular length.
I'm just getting started on electrical engineering, so I might've missed something (most likely, actually), but as far as I know at the moments at least, harmonics in this context is more about waves from different sources interacting.
So I'd say they are related, albeit not the exact same. And I'm sure there's someone out there who could easily make a 6 hour lecture on this question alone.
Thanks
Very much clarity
No i want to know what a guitar sounds so good to me in harmonics
Anyone notice lieutenant Hawk eye
Captain Hawkeye
Fantonomisk. Thanks from Denmark
Excellent Knowledge for Musicians!
As she said it's cool to play at a party but doesn't explain properly. The sitting guy just ruined it by already knowing something
So why does c and e have "same harmonics" bc of frequency played and registered and impression
Are the other frequencies a factor of time ? Like does the base note sound first and the rest comes after?
Good question
For this demonstration, the answer is yes. Reason being, the notes she is playing are not produced at the same time. Another good rule of thumb to remember is that on a spectrum analyzer, the up axis represents frequency and amplitude. The horizontal (side to side) axis represents time. Bare in mind that spectrum analyzers can sample multiple frequencies at the same time. So, for example if anther person played a flute along with her, you would see their frequency spikes on the same display.
Awesome video.
Was that Close encounters of the third kind?
Where's the rest?
Does anyone know what this app is???????
Still struggling to understand\
?
Someone pls link me the whole clip.... Pls
Oh my god is that Hawkeye from mash?
yep
Nikola Tesla: 11.78 hz (Earth) 3.69, 36.9, and 369. Is the secret to the universe 434?
What is this program called ?!
Alan Alda?
yep
but why
Nice 👍 Thank you for Sharing 🤍🤍🤍
Thankfully he was there to explain succinctly that which she couldn't
She was actually talking about much more advanced topics, he was just clearing it up for the slower portion of the audience.
the way she talks to the audience makes me wonder if they are all 5yr olds...
how about talk like a normal adult and leave the immature banter out...
the guy sounds like donald trump
Just an East coast accent.
absolutely not
Didn't understand what harmonics are. But did no one notice her "blowing harder and harder"?
;)
Overtone series ...
She's a fox
why so?
@@jawadulkarim8877 She is on the thick body side, with ample curves. Some guys appreciate that I guess.
That is cool (in terms of her body) I wanna have her social media ID.
Resistance is futile! Be susceptive to trying out this simulator! probe circuit solver on the playstore!
