3. What is the difference between a Noise and a Note?

Both noise and notes are mixtures of sound waves at different frequencies.
A note is made up of a ripple pattern which repeats itself over and over again in an ‘ordered’ way.
While a noise is made up of individual ripples which have no relationship to each other and do not repeat - and so are ‘disordered’.
If an object moves, it causes a disturbance in the surrounding air which ripples out as soundwaves. If the object vibrates with a fast and repeating pattern, like a string, then the sound waves will be evenly-spaced and regular; that is, the air particles are squeezed together into evenly-spaced waves. These evenly-spaced, regular sound waves are heard as notes with distinct pitches.
But, if you drop a vase or slam a door shut, you hear a noise which is made up of a lot of unrelated frequencies with no repeating pattern - and so will be a heard as noise with no defined pitch.
To be a note, it doesn’t really matter how complicated the individual ripples are, as long as the pattern repeats itself.

It's very rare to find Music theory explained in informative and interesting way; thanks and looking for more.

This isn’t music theory, it’s acoustics.
This is pure gold. Just knowladge, just a perfect video to understand music. Congratulations.
Little did I know I was learning about notes in my bath tub at the age of 5
I LOVE YOU WHO MADE THIS VIDEO. Just what I needed!
Man, you should talk Sal Kahn. The world needs to be exposed to your work. Genuine hero.
Excellent video. Clear, informative, and nicely put together with the visual and audio effects. Thankyou very much.

5:53 that's why when i don't have an amp lean my guitar's headstock to onto my room's door. a natural amplifier!
Very helpful for me the visualisation at 2:48 (the water-Waveform -Relationship) THX

No problem. Thanks for the comment :)
the part with the skull was hilarious! xD
Super video, thank you!!
2:05 This is also how we hear voiced fricatives. Voice=note, friction=noise.
this is the most underrated series ever, homies drenched his bathroom for us
Tesla... Sound, vibration, energy Its ALLLLL right here. Well done
Do you ever create bad videos? haha As always, really clear explanations and you really get to the point, thanks again for your vids!

You have truly amazing material, thanks a lot.
I wish this had more views. Such great content!
the vibration of your skull - rofl! Excellent stuff, man, thanks for the education!!
great video, love your effort to educate people
Ahhhh the bathtub example is so brilliant!
Thank you for this video! it is really interesting ,and helpful:D

You are great man😍
Awesome, really interesting! :)
great videos my dude :)
omg, now I'm going to try to break down pattern in the noises I hear to see if there is music within noises.
if my physics teacher had let me see this video, I would not have failed the harmonic motion class
this is great
캬~ 진짜 명쾌하고 심플한 설명이다
so at 7:15 area when talking about nodes, and it shows the wave moving with nodes pointed with arrows, is that like a guitar string or the sound wave the instrument is making. I know you said nodes included the ends of the guitar string but I'm trying to figure out how there could be other nodes on a string besides them. Wouldn't it be moving up and down all at the same rate? You said standing wave as well, so I'm just not sure. At any rate these videos are excellent and appreciate you making them. Like the simplicity and quickness. Helped me learn a lot just from searching one question lol
😮 amazing
very interesting
04:35 great demonstratiom 😁
It there a video that teaches point source/line source?
The concept of the tuning fork and “noise-canceling” headphones. Is this how Apple & co. do it?
2:00 This makes noise sound easy to get rid of (algorithmically)

Great video! I have a question. Does a instrument is designed to amplifie its natural frequency? (shape, size, material, etc) I mean, when you play a notes will you always create resonance?

Noise = Indefinite pitch Note = Definite pitch

A noise sounds like it has pitch
idk why I watched this but Im wiser now
i would think the difference between a note and a noise is the same as the difference between a plant and a weed. noises and weeds are unwanted, unappreciated, unplanned. so it would really kind of depend who you ask...based on their opinion.

theres even euphamistic terms for each. a weed that produces good things is called a volunteer. and a noise that is musical is called musique concrête. (mew-zeek kon-cray)
Did you take a bath after that video 😂
That water does not look clean...
