Sound is a wave, that is, it’s a vibration that travels through a medium, like air and water.
Sound waves cause changes in air pressure as particles bunch together and spread apart. Now, we can’t see these ripples but our ears can hear them. When the waves reach our ears, the air pressure goes up-and-down and this makes our eardrums go in-and-out at the same rate. Our brain analyses these signals and interprets them as sound.

YOU ARE A SAINT!! I cannot learn something if I do not understand the genesis of its mechanism. I've been on a lookout for lessons in music like these for years and you are the only answer I've found. Thank you soooo much. If you have a link where I can contribute to your channel through donations please link!
This series is EXACTLY what has been missing for me... other commenters have mentioned the link between music & the physics of sound. I've played instruments since the age of 5 and have been dying for a simple-to-understand, science-based explanation. Finally!! Is there a place to contribute something for your efforts? I'm so grateful.
Hi Doug
Glad you're finding these vids useful :)
Yep, I accept donations through my website here: www.thejazzpianosite.com/donate/
HOW MUSIC ACTUALLY WORKS SERIES is the best it solved my frustration on trying to understand how the Piano notes,Chords,Scales are arranged they way they are arranged today. U just don't know im that kinda person that wants to know were things truly begen, in order to grasp it fully. Very much thank you for this hard work of explanation,
Thanks, mate. Glad to see some people are getting use out of these vids. I'm exactly the same. I think this stuff is fascinating. Music from First Principles - really mind opening. Anyway, cheers.
Walk That Bass Hello, Im a year late but I can totally relate. I’m not sure why don’t teach us this way in school. Learning the fundamentals of the universe.
I feel absolutely the same. Started to learn guitar chords, asked Google why are they shaped specifically like this and ended up in physics :D
Loved this Jazz Piano Tutorial
Hi
This explanation is way better than my physics teacher
That's why we all here 🙄
Yup
That’s why my teacher sent me here
Truuuth 😂
You commented this 3 years ago
never disappoint: great stuff. Dig the sfx as well
Tomorrow i have a test about 18 page of sound and you ( saint) reassuned all of this 18 pages!! Thanks!👑
Can you please make a video of "production of sound"...
A sine wave from the center line to the top of the wave, back through the center line and down to the lowest point and back to the center line is called what?
1:24 Correct me if I’m wrong but there is is no difference between sound waves and water waves. This is a difference between surface waves and waves inside the medium.
Excellent series, absolutely captivating! Thank you
It seems to me that the teaching of musical theory should have included some of these scientific topics in order to fully understand the why behind things and not just take them for granted
Thanks
Interesting and simplified way of explaining the topic of sound to students, Physics teachers can take advantage of this video. Excellent video. Thanks.
I'm hooked. This is amazing.
Glad you like it, mate. Thanks for the comment.
Wow this video is great, you definitely deserve more views
If the speed of sound travels at 343 m/s, and frequency is determined by how many waves PER SECOND..... does that mean by the time we hear the sound 1 second and 343 m/s have passed?
Excelente😊
geat video, very interesting and nicely animated
Thanks, mate.
thank u this saved my life.
So isn't it heat ? Temperature ? But since it's a wave it doesn't matter because in the first second it heats up and in the next one it heats down..maybe even a millisecond. So it's just oscillating temperature, right ?
Bulk water acts lon-digit-unal. Strong sea or ocean botzom currents.
Likewise sound in CLO-SED spaces...aka META-mat-eria-L is TRANSVERSE. The more syMMetry is broken, coupling is easier.
What is the smaller the number of cycles per second of a sine wave?
🎵=🌊
Thanks 😊
looking forward to these 8)
how would you explain and visualize "analog" & "digital" sound?
I'm not OP, nor an expert in music. But there is no such thing as digital sound, any digital signal is converted to analog before it can be played through a speaker. You might be asking about digital (CD, DVD) vs analog (vynil) media? In that case I misunderstood your question.
@@lucascipriano1665 it's not about how it's reproduced, but how it's generated: digital (quantised bits of information) or analog (continuous physical properties of the electronical components)
... if you have digitally low bit rate it won't get better with analog speakers (you will hear the digital difference, as was in the 80s)
Thx my new physics teacher
Nice work
Yeah but are sound waves really 2 dimensional? Or are they like 3D spheres?
I like to think they are 3 dimensional. How could sound waves be 2 dimensional when all sound is created by 3 dimensional life? When you hear thunder, it’s the friction of 3 dimensional molecules that helped created the sound.
Thank you
great works....
Cool vid :)
OK, another chapter complete
great vedio
1:24 is that even a sine wave
Who was put here from school during quarantine
Federico Paez me lol
Isabel Grey haha 😂
Sadly me-
Federico Paez hi fed
Me, but my teacher didn’t put in the right video she put in a cat screaming.. XD and..... now I’m looking up what is sound videos.. ;-;
I like it..........amen
Who else is here because of there teacher during quarantine?
If y'all still confused

17 second explanation
bitch
What the flip
Sound is a vibration.. of what? We can say that, for instance, a food blender vibrates and also makes noise. We can assume that the phyisical vibration of the blender is vibrating the air around it, but they are not making the noise. I'm astounded there isn't more advanced research into sound :l
William Smith um, what? The sound is the vibration of the medium being processed by our brains through the function of our ears.
The vibration of air particles/molecules (as waves)
*Invisible sound waves
The definition of Spectral is, like a ghost.
my ear drum is listening

I HAVE EBOLA
Did u die

ROARING RECORDS GANG GANG
No one else is here because they want to ur teacher sent u here right
A potato gamer 🥔
Who is hear after 7 D
I disagree saira
booooooo
Fuck u
This is best 🥹 i m having exam and can't appreciate more🥹 thank you for such a wonderful explanation
What is the larger the number of cycles per second of a sine wave?
booooooo
Fuck u
