Observ45er In you fourth paragraph titled “the real Bernoulli principle” you explain that speed is a result of the change in pressure. Why? She makes no mention the speed of air coming out of her mouth being the cause of or reason why the paper comes together 🤔 I realize her explanation and description of the Bernoulli principal may be a little flawed but this isn’t for science majors. This is for vocalist trying to better their technique. She also made sure to preference this video saying (I’m paraphrasing here) that in high school she wasn’t very fond of the subject matter she was about to discuss, as if to say that this was a laymen explanation and I’m (meaning her) not the best person to learn the Bernoulli effect/principle from. That being said you mention that the Bernoulli effect takes place inside the “blower” 🤔 well she’s talking about what’s going on inside the “blower.” I understand that the demonstration may be an entirely different set of principles but she was talking about vocal chords and what was indeed going on inside the “blower” right? the paper wasn’t really the focus. Maybe I’m wrong I dunno.... anyway my point is this isn’t really a science place to be discussing science lol 😂 Still, thank you for further explaining each effect as I do enjoy both subjects. Music, and Science.
@@skizzlemane1 Thanks. Well, she decided to try to explain the science. Singers need to concentrate on what to do and though it may be interesting to throw in some science, it isn't necessary, but it should always be correct. Bernoulli's Principle is one of the most misunderstood explanations of the phenomena. . The ''blower" for voice is the lungs. Muscles compress the lungs increasing the pressure in them, thus providing the higher pressure to force air out past the vocal chords into the now relatively lower atmospheric pressure. I'm not going to watch the whole thing again after 2 years, but her words must have at least implied the common speed-causes-lower-pressure misunderstanding. .. Clearing it up may be futile, but a quest of mine... Cheers
@@skizzlemane1 The Bernoulli Effect/Law/Principle is best observed with a very high larynx and a gentle "whoooo" or "heeee". It does work, it does take time to develop, and it will make singing across your whole range easier.

Thanks, I finally get it now :)
(speech and language therapy student)
Same here ...i got it too...thank you so much for making it clear within few minutes
So helpful for speech science, thank you!
So simply and helpfully demonstrated, thank you! ❤
So great! Sad that I don’t see this being taught by vocal teachers anymore
Very well explained in a very short time
Hi from 2022 !
This video helped me so much in my SLP course
Thanks✨
Thankyou for making this so simple to understand!!!!
Thank u!! So easy to understand, now.
so well explained !
Atlaaaaaaaast .....
Thank you ...
From Singer ..😊
Thanks! Got it!
You're my hero 😭😭😭
Thank you so much! ❤❤
Thanks!!!
But how vocal folds produce multiple frequencies I,e harmonics at the same time
Both the various layers of the vocal fold (and their varying stiffness) as well as articulatory/resonant chambers (i.e. nasal and oral cavity) can affect harmonics and resonance
I'm here bcos of the Bratz movie
