I still want to know WHY my tongue and mouth know how to create an exact, precise pitch absolutely effortlessly. Has my tongue memorized the shape it must be to create each and every pitch? This fascinates me. I can on the first try make any sound I choose. I can match a sound in a song or a note not on the piano without trial and error. The pitch is right there immediately without any thinking or trying on my part. How do I do this? How do I know? If I were playing a wind instrument, I would be taught how to get to any particular note with some mechanics. But in my mouth, you would think it would be hit and miss, but I can do it precisely and immediately without any chance that I might flat a pitch or not reach it clearly. It's mental, I know. But is it a skill we are either born with or not?
Interesting follow-up question! It sounds like what you're describing would also apply to singing as well. Some people seem to innately be able to hit the right note without much thinking, while others do have to use trial and error. I would guess musical training of any kind can help improve this ability, but I don't know that for sure. With science, answers usually lead to more questions. :)
It's similar to how we instinctually learn how to pronounce different sounds even though we don't know at the forefront how it happens.
I like how she thinks through the process of what possibly creates the phenomenon of "whistling".
12:30 I'd like to add the it's the kinetic energy that moves through it that we hear, as the air itself only moves through because we're only feeding into one side of the instrument. A drum, rubbed with a gummy mallet is an example of a tone produced where there's minimal motion of air "through" the instrument, but the kinetic waves are cannonlike
Great example!
@@isleptthroughscience Thanks! ^^ I thought it was pretty interesting; it reminded me of learning about waves in water where the water moves mostly up and down, and the energy is what truly travels
Really great man❤
After watching video I still have same essential question. Where is the difference between blowing through the straw (there is no whistling) and through the whistle (flute has almost the same shape as straw). I understand things you solve in this video, but I am unable to join them to understand where the waves what makes whistle comes from. I can found the difference between flute and straw and I know what part makes the difference, but I cannot imagine how it exactly the pressure differences are created.
But still thank you a lot, this is the closest explanation what I have already found.
I don't know that I will be able to sufficiently answer your question as you are looking for a much deeper answer. However, I think the fundamental difference between a straw and a whistle (or a human whistling) is the difference in resonance frequencies between a tube that's open at both ends and a tube that's only open on one end. They need different wavelengths to resonate to produce sound. You also mentioned a flute, which is similar to a straw in that it is open at both ends. Perhaps the size (diameter) difference between the straw and the flute changes the frequencies that will resonate so that we either can't create them or can't hear them. It's a great question!
@@isleptthroughscience Thank you so much! I believe your contribution has played a significant role in helping me understand better. It seems that there are numerous ways to produce sound. However, some of them may be too quiet for us to even notice. Would you concur with this particular observation?
Yes, there are sounds that we can't hear. Sometimes it's because they are too quite, but other times it's because they are frequencies of sound that our ears aren't sensitive to. A dog whistle is a good example. The frequency (pitch) of the whistle is too high for humans to hear, but dog's ears are able to hear those frequencies, so they respond. Similar things can happen with lower frequency sounds as well. Elephants are a good example of animals who can hear frequencies of sound lower than humans.
Hello, from Turkey we had a very brutal earthquake disaster. ın disaster main problem we do not know which people where in the debris. so I decided to design a whistle also can suitable for the body. thanks a lot for making these mini-lessons.
nice thanks for this
Why scientifically does whistling work?
Depends on what you mean. We tried to explain it in the episode. Do you have a question beyond what the episode covers?
This might lead to how we can hear others, murmuring.
