The Math Behind Music and Sound Synthesis
Ғылым және технология
We hear sound because our ears can detect vibrations in the air, which come from sources like everyday objects, speakers and other people talking. Why do certain musical intervals sound the way they do? How are electronic music instruments made? This video will be all about sound frequencies, wave shapes and the math behind it all.

came directly to the comments because of that
when he started building the song as he was explaining the waveform sounds i wanted to cry. that was so beautiful
This channel have so much potential
that little beat at the end was a banger
This covers so much ground in such a small amount of time, really helped by such intuitive animations. I’m going to share this with all my musician mates.
Your channel reminds me of the best parts of college. Learning different concepts in a relatively short span, and being endlessly fascinated with the core concepts. Thanks for taking the time to make these.
I started making electronic music around 2011 when my friend showed me a java programm that would make the speaker play a series or beeps. I started off writing music exclusively as rows and rows of ascii code that would then be read by some newer version of the software provided by that friend and generate a .wav file from that. The catch was: every instrument had to be defined as a math function of time. Coming from that perspective, i can tell you: Sound design is a lot harder than just adding some waves. I tried, and i failed a lot. I was so happy the first time i managed to make a decent FM bass that the sound cougth me completely off guard. XD Even worse, i was never really into games or chiptune stuff; i was just to lazy to install FL studio or something similar that would make me some "professional" tunes. I eventually switched to linux multi media studio around 2015, but came back to that raw saw&square sound last year. Now i'm trying to make the most out of it and see if this weird software where every sound is pure math-hell could be used for educational purposes. The new version featues a simple syntax for microtones and even has some basic filters. And we simplified the syntax a lot. I'm currently preparing a bunch of slides for a small presentation or vid about the math of the so called microtonal intervals and natural/non-12TET tuning systems. But my channel isn't exactly an educational channel, so it may as well be a waste of time or just something for myself to spend the time in lockdown. But if you are curious/interested in this stuff i could send you a .zip with the software and some demo files for easier demo sounds than the ones you used for this vid (like playing actuall 400Hz tones or really perfect fifths ;) ). Have a nice day and stay save :)

But i borrowed a friends touchscreen once for a live performance on an t+-integrated virtual microkeyboard where i could only press one key at a time, so it's getting there XD still no real time manipulation, but one could type in the instrument definitions as you play and the new notes use the new parameters. It was just inteded as a quick testing feature, but it is possible to perform with that... ^^

Sup, i know you probably wont see this comment, but I just want to say that this video is amazing. I was doing presentation for my math class about math in music and this video gave me enough knowledge. It is also made a way that I can understand it even tho I'm not a native speaker. Thank you very much for your work.
Ive noticed many smaller channels popping up recently with massive potential. This has got to be the best, i love how chill the whole video is

This video is amazingly put together, thank you for making this
I've been watching your videos the whole evening. You made my day.
Amazing video man! I rarely comment on videos but think what you do is great! You manage to explain the mathematics behind it quite intuitively while also making it appealing, factual and to the point. Looking forward to the moment your channel blows up!
Probably one of my favorite videos on the internet right now..
Oh man, just found my new favorite Chanel, thanks dude, I was really needing this knowledge, and it up with the sick beats to
This is beautiful. I’ve always wondered how music is mathematically structured-especially electronic music-and this video offers a brief yet clear introduction of the core concepts. And the culmination of everything we learned at the end with all the waves coming together genuinely brought tears to my eyes. Thank you.
To be honest, I've never seen a video as good as this in 2022
this video is so incredibly underrated and interesting, love the way you explained and animated everything
The beat at the end was really nice!
I love this channel so much. You should have at least a million subs!!!! Such quality is so...beautiful to see. Please keep up the good work!
This is an incredible video. Even as an electronic music producer and someone who loves math, physics, and sound design, I still never fully understood how these sound waves worked. You explain everything so clearly and make it enjoyable to watch. Thank you.
Great vizual effects!! this is simple and clear. I want more series. nice job!
you are a freakin genius homie! keep up the good work! the beat at the end was amazing!
wow, I love the fact that this video is so detailed and explains everything so well! I normally don't leave comments on videos, but I really feel like I should do it here for the algorithm! :)
I think it was the clearest explanation of the fourier series and sound design that I've ever seen. Amazing job.
This is incredible, the "editing" since you made the graphics library, the story telling, the content in it, everything was awesome.
The way you summed up and delivered these topics was brilliant!
I stumbled upon your channel today. What a revelation, I subscribed straight away and love the maths. Your channel never showed up in a search of KZread channels on maths, so today was pure luck. I'm skimming through the videos, but at some stage, I will be binge-watching them. The content and the beautiful graphics are treat. Cheers. 👍
Absolute gold. Completely captivating
Thank you for so simply and quickly explaining these fundamentals with great illustrations! I will keep coming back to this and your channel!
This got recommended to me. I thought I would knew all of this already, but still learned some new things. Keep it up!
Amazing video! Your videos are all of phenomenal quality. You have a true talent to break a complex topic down to essentials, and then build it back up clearly, logically, and with concrete examples. Looking forward to your future videos!
Damn your videos are so good, incredible content. Wasn't expecting a sick chiptune bit at the end, love it!❤️
Man, I have seen so many people try to explain this, but you did it the best by far. Specifically I was always confused about how the square, triangle, etc. waves could be the "sum" of a bunch of sinusoids, it didn't really make sense looking at the shape. But this video paired with the calculus class I am taking really helped me understand where that comes from. Thank you so much!
The way you explain that is clean like a professional mix ;) Thank You!
This is such an amazing video!!! Thanks so much for having this up on the web!

Incredible work, you got my hype for your next vids :)
This gave me such better understanding of music it is crazy! It just immediately clicked with me thinking about how our brains superpower is abstraction. It also finally made a lot of sense that culture impacts our musical understanding and preference. Especially why the rough integer approximation in a triard is working if you consider western music theroy. I would love a follow up video talking about a few of those things. Awesome work! It really inspired me and probably will help me understand many more things in the future.
Such a beautiful description, and such a sick beat it had me dancing instantly!
When the music started dropping I thought I was listening to The Toxic Avenger. Really cool, GJ man.
Awesome video! Thank you!
This is incredible. I'm speechless. I am without speech.
That explanation was super. It is like music is singing out the beauties in mathematics. Also, love that last music where you combined all the instruments together into one great orchestra!
Great explanations. You brought maths, music theory and instrument synthesis together very clearly.
There are 12 tones/notes over 14 steps on the piano if you look at it from a mathematical stand point, the pattern repeats every 12 keys and from A to A key is a whole octave and every 13th key is A key and first key at the same time, what I am saying is it is exactly 1 octave from A key to next A key, the frequency number doubles, it doubles in frequency, now I'm glad we had this talk, I feel much closer to you... Consider this: A key frequency is any whole number because it's just logical for it to be a whole number if you could guess it to be any number, it would probably be a whole number so now we have one octave from A to A, step number 1 is A#, step number 2 is B, step number 3 would be B#, (it's the key that is missing, the step exists) step number 4 is C, step number 5 is C#, step number 6 is D, step number 7 is D#, step number 8 E, step number 9 would be E# but the key is missing, the step is still there step number 10 is F, step number 11 is F#, step number 12 is G, step number 13 is G#, step number 14 is next A so there are 12 keys over 14 steps in every octave, it's 14 because FREQUENCY is a LiNEAR VALUE, it's a curved line, a sine wave, a wave so if 7 whole notes exist there also 7 half steps and total number of half steps is in fact 14 not 12, exactly 14... B# and E# do exist in nature, in physical space B# and E# without a doubt exist and this makes music theory fundamentally flawed whether on purpose or not is another question, however one thing is clear, as day, musical western theory is a falsified way to TUNE THE PiANO, well simply because all the ratios to every key except to the same key in a different octave are all wrong... A Frequency + (A Frequency ÷ 14) × step number A0+(A0÷14)×14=A1 A1 will double the frequency is how you know it's proper Also the key between two A keys is D# it's the 7th key out of 13 keys so it's exactly the frequency in the middle of the given octave so you can figure it out in your mind and check it with the formula considering you know what the step number is(#7) This is the proper formula for every key, not divided by 12, only by 14 Also piano should logically start with A key on the most left because it's the reference key and the first audible frequency and it would make A key also the most right key, making it absurd to start and end the piano keyboard with anything, a A keys First audible frequency is an A key, or should be A key and it's probably 28-37Herts....well somewhere in this range because it's the first audible and musical, so to speak sound and it's basically the lowest Key on the keyboard!
