@@Gonkee I love that triangle wave line but you changed the melody on the 2nd repeat and that didn't show in your shown wave pattern. Also what software did you use to make the beat?
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.
Wow, you explained it far better than anyone else! I needed this kind of scientific explanation of music, all other people talk about "rules" and that "you have to feel it, just redo it over and over and you'll get it". This filled the empty space in my soul 😍
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.
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 :)
Did you try live coding with SoundPi, SuperCollider or sth like that? I guess with such background you should do really well in tweaking stuff in realtime )
@@VRchitecture I'm seriously considering just abusing a pico for that; didn't find the time though. 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... ^^
Lol I would love to have that software! I'm really into microtonal stuff (due to Jacob Collier 😏) but all regular programs are too grid-based for that. I would love to be able to use something like this!
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.
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!
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.
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!
Before seeing this video, i suspected that there was probably some maths behind sounds. This video confirms it and is exremely clear and helpful. Thank you.
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! :)
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.
You made me download Matlab again. I am an electronics & telecommunication engineer. I was always feeling that i can connect math. with music. However, i could never find a clear video which explains basics that good. Very good job...
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 UA-cam 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. 👍
finally someone that simply explains how those waveforms are created, instead of just saying "yeah you have a triangle and a square, they work just like sinuses"
This content in this video is spot on. Somewhere between what a Dan Worall or Steve Mould might do and a visual Presentation like in the Vox Earworm Series you seem to have found your place. Everybody here seems to agree: we love it and cant wait to see more of that
Great animations :D Sidenote on Fourier's Theorem: It's not like writing some sound as a sum or integral of sinusoidal waves "may work", it even works for non-periodic discontinous signals like a kickdrum or a sudden blast, or various noise, although that is not as obvious as the regular version of "instruments have more than just one frequency". The only limitation to it's applicability is the range in time you want to cover. The larger, the better your results in terms of precision, but the less information you have on individual elements within that time frame. That's the famous uncertainty principle, which for some reason people only think of as "something with qunatum, right?". But in general, every function whose integral over the square is defined (in other words: it does not blow up to infinity) can be built up from complex waves. That even holds for something like a parapola or an exponential function if you limit the the range of the integration to some finite limits.
That's amazing making some calculation on music tone frequencies and all make sense because it showing what makes music sounds good or bad. Actually, I'm not doing math during composing piece because it useless to me. I only use my hearing to identify those dissonant notes that I should avoid in composing some piece.
I Think your channel is gonna grow big. I feel proud to be here at It's fundamental wave state😄. Very nice explanation, and the music at last was sick.
I’ve been waiting for a Mathematical run down just like this for a very long time. As someone who enjoys learning about the mathematics in music, this was a brilliant bideo

This is wild because this mean that irrational numbers sound better and any irrational number multiplied will make a irrational number so frusciante was right by detuning to get a better harmonic.
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!
Thank you so much for the cool education on synthesis ! Thanks to you now I am now a sound designer and a midi musical piano instrument sound creator for a hobby at home in my recording studio ! :)
Really enjoyed that. Flyover which quickly touches the math of music and spans to synthesized sound design. No wonder you get 10% like rate. This video should receive an award. Cheers.

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!
