More Polyrhythms - Music Theory Crash Course
ฝัง
- เผยแพร่เมื่อ 29 มิ.ย. 2021
- There are many different ways to look at polyrhythms in music and today we are looking at a different one, using star shapes. Last time we visualized these rhythms using straight sided polygons but I had a great comment on the last video that suggested using a star shape. So after many hours of making the new animations here are the more common polyrhythms you will find in music visualized using star shapes. This is an exercise in visualizing musician not a method for teaching polyrhythms. I hope you enjoy!

That 1:2:3:4:5:6:7:9:11:13:17 polyrhythm could've sounded awesome if you chose notes that harmonized well with it but great video nonetheless
Agree
It sounds great when it was 1:2:3:4:5
I think it was meant to be a quartal chord built on perfect fourths
@@TimothyLowYK guess that explains why quartal harmony probably only sounds nice to a certain degree cuz when a lot of the fourths are stacked it doesn't sound as great compaerd to the stack of fifths probably
Maybe if he adjusted the pitch to match the relative frequencies? I know 2:3 makes a perfect fifth if you speed it up enough.
Its quite interesting how you can hear the rythmn go almost go to unclear noise. Like a toddler that over enthausiastic rings the doorbell.
It all started with 7, nobody likes 7
to be fair it was played really fast
@@cl0p38 all prime numbers are weird except 2 3 and 5
Go 2x speed
I like how the ending sounded like someone playing random keys, laying their whole arm on the keyboard, playing random notes again, and repeating.
and then ends with a peaceful silence
I USED TO DO THIS😭
One of them sounds like a car door open noise i cant even 😭😭😭😭
i want to see that 1:2:3:4:5:6:7:9:11:13:17 polyrythm:
1. with just the dots
2. using the harmonic series as the notes
Was going to say the same, numbers equal harmonic series ❤ it's like a recursive harmonic series in that way.
@@PabloGambaccinitrue yeah actually
59th like
@@PabloGambaccini3rd like
I feel like the out-of-harmony notes can make its own unique song for certain scenes in like, a movie. Each polyrhythm adds onto the chaos, until it eventually transitions from music to noise…
I've been playing drums for 16 years and for the first time in my life I managed to REALLY visualize what a 6:7 is actually doing in the background. Seeing it was so much easier than just clapping to the beat. Thank you for this!
6:00 The fact you chose the tritone of all things on this exact polyrhythm
an alarm sound
And even it’s 9:11 (*police intensifies*)
ofc 9;11

I love how the sound of all the combined polyrhythms take a little 'breath' on the beat (at the bottom of the circle).
Great video! Thank you!
I think the stars are really effective, visually!
I think there's a metaphor for the tritone being the most dominant sound in a cacophony of noise.

You can also visualize x:y polyrhythms using an y:x billiard table with a ball that starts with 45 degrees. The reason it works is that reflection (the way the ball bounces off the wall) is the same as if your replicated the rectangle across the plane, and looked when the equation x=y hit the walls. It hits a vertical wall every y seconds, and a horizontal wall every x seconds.
shouldnt the dimensions be 1/y:1/x?
actually no wait, you explanation makes sense because (1/x)/(1/y) = y/x
7:47 the last visualisation was a bit messed up, becasue there were many different stars hitting at the same spots. It would be super interesting to hear how prime-numbered stars would sound like. Great work tho, keep it up
2:3:5:7:11:13:17
:19:23:29:31:37:41:43:47:53
“This next song is called ‘A World on Fire’”
5:2 is the best of di-rhythms. Because more points makes it so strident and fast. Others like 2:3 and 3:4 are simple ratios.
The end was everything I wanted.
17 is so ridiculous it’s so hard to see and I love that!
8:29… ah yes… SHEAR CHAOS!!!
This reminds me of watching someone else's turn signal swap from in phase to out of phase with my own.
Nice, similar concept: watching the footsteps of two people walking abreast. If you're like the rain man you can calculate the ratio of their heights by observing their steps fall in and out of phase
love this, but it would be so much cooler if the notes matched the interval ratios of their polyrhythm
The more complex the polirythm the more it sounds like a jackpot
This is absolutely brilliant, thank you so much for making this!
This is really good, I didn’t understand how to visualize polyrhythms other then playing by ear before this.
the best way to think about polyrhythms is 2 different car blinkers started at the same time, looking like they are in tune but they they leave sync then join again
I think polyrhythms are amazing so many colorful possibilities at your fingertips. Thanks for helping us expand are creativity.

Extremely educational video for me in understanding time signatures and changes to them in music. Very well done. Please do more of these.
I love how you built up to that tour de force polyglot polyrhythm. Chaos that is completely coherent, symetrical, and orderly.
Each number in the sequence is the sum of the two numbers that precede it. So, the sequence goes: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on. The mathematical equation describing it is Xn+2= Xn+1 + Xn
there is proof that musician actually use left brain more than right you seem to be the proof
Uhm, Not sure, that is Fibonacci series. But the polyrhythm goes
1:2:3:4:5:6:7:9:11:13:17 which is not the Fibonacci Ratio
@@rs-tarxvfz was about to say that
I was like, "is this the right video?"
you can use bezier curve to do better stars and having the point following the curves better
The 3 points star is the most unique looking and sounding i've ever seen.
Funny thing is, in the end i could clearly make out the 2:3 rhythm against the noise
Consider using the harmonic series for the final omnipolyrhythm!
But yours sounds great!
5:2 has great tension, beautiful! Is this software available? Did you build it with manim? thanks
I love how once the 1:2:3:4:5:6:7:9:11:13:17 polyrhythm is fully assembled it sounds like a pianist have a seizure while periodically having moments of clarity.
The 1:2:3:4:5:6:7:9:11:13:17 sounded like an alarm that got more stressful every second
i did some learns, but maybe do a more distinct sound like bass vs guitar (i'm not the greatest on the keys, and it was hard to tell them apart without watching). thamk.
Great video, have been struggling to understand polyrthyms, I am self taught musician and this is the best video, thanks so much dude!
Loved it man!!! ❤️❤️❤️
This is very cool!
Cool tutorial. . quite easy to play
i love the final design and for what ever reason i thought i heard E before the 17 star got added-
If you speed up an rhythm you get a tone. If you speed up a polyrhytm you should get a chord. It would be interesting to se the correspondens between chords and polyrythms.
funny how the 9:11 example has the two notes a tritone apart (which is a rather dissonant interval); wonder if that implies something related to said numbers
Soo when is the app coming out?
5:2 is pretty neat sounding
Absolutely brilliant video thank you so much. 👏🏻
I noticed that the (high) frequency ratios of each of the first examples polyrhythm matched ;) nice
I know some polyrythm because I know how they sound and I can imitate, but if I have to make a new polyrithm that I don't know (like 5:7) I would need to do the "maths" and after that remember the rythm and just playing it by memory. Is there any trick to not play the polyrythm by memory and doing the rythm just by heart?
Can you maybe also talk about if there is a difference between 2:3 and 3:2 as an example
There no real difference I think. Might be wrong, but I think it's just visually note a smaller number:larger number.
@@phildiop8248 there is a difference actually, the second number in 2:3 and 3:2 is the "main" pulse, so if it's in 2:3 it is a beat of 3 with 2 beats countering it, and vice versa for 3:2
@@inari.28 That's interesting. If both pulses act equally or if there's no ''main'' pulse, would it be small:large?
13 against 17 sounds the best in my opinion.
Thank you for teachimg me the basics
The use of the tonic fiths dominants and octaves majors and minors for the different ratios are not lost on me.
1:2:3:4 sounded really good and then 5 brought chaos with it
even 1:2:3:4:5 doesnt sound bad and tbh that and 7:9 ontop sounds ok i guess. beyond that tho is chaos
God dammit, now I want a music maker using polyrhythms!
Amazing video..
very cool video watched today on TH-cam
Ligeti would Looove this big combined one at the end
very interesting! thanks
Really interesting. Thanks
at the end, was the volume of the 3:4 polyrhythm boosted? I could still hear it through the noise, even when i was focusing on something else
Time to make a song based off of the elusive 1:2:3:4:5:6:7:9:11:13:17 polyrhythm
5:56 yeah im pretty sure it sounded like that
Can you use all polyrhythms (i.e. 1:2, 2:3, 3:4, 4:5, 5:6, 6:7, 7:9, 9:11, 11:13, and 13:17) to make a song?
Reason why I asked this question is that some polyrhythms can be used to make music. For instance, 50s music uses polyrhythms to make the music more upbeat and hip.
2 Years of explaining how polyrhtym works, and i look confused, and ask;" Why? ".
10 minutes of a YT video, and i go;" ooooooh, that explains a lot. ".
Tritone interval on the 911 polyrhythm, I see you
that final polyrhythm almost sounded like something from a horror movie
That last one sounds like a sorting algorithm.
What is the equation for figuring out the curvature of each star?
Idk, but I'd roll a smaller circle inside a larger one and figure out the trajectory of a single point.
but if you do 1000:2000 for a star, then it will look like a circle with a thick edge.
and if you use marks for 1000:2000, then it will be 2 lines.
Love ❤️ this, where can I get one of those stars 🤩
This visualization makes a lot of sense now that you can actually over lap them and see which beat plays when
even with all that noise the 2:3 combo moment shines through like a beacon
Its amazing.
Why not using Left-Right channel pan for the beats?
It’s very interesting that its has 17 parts
Visually and mathematically beautiful
THAT 3:4 SOUNDS TOO AMAZING
5:56 "9 against 11 sounds like this" *Airplane crash sounds*
Chopin's Nocturne in B flat minor op9 no1 has a 11:6 polyrhythm in the second measure
Probably that I almost saw the 4:5:6:7:9:11:13:17 almost like a circle spinning but can we do 2:2:2:2:2:2:2:2:2 that look like a circle spinning not in the same spot i mean all spots of a circle
Wich software is used to do these polyrithm animations?
9:11 sounds like an emergency if you think about that
That last one was a real toe tapper
I love that 1:2:3:4:5:6 polyrhythm so much, 8:22
Primes against squares are nice.
6:42 that kid’s going ham on that piano
🤩 amazing
Do poly rythrms of Fibonacci sequence .
The ratio converges to phi
overlaping stars are much better to show the phase difference between two divisions
What app/software do you use to create these polyrythm?
For the visuals I use after effects, and for the sounds I use Ableton Live or Audacity depending on how complicated it is.
@@Oddquartet that software for a pc or can I download it as an app? (Or both)
There's actually an application for pc and Mac called Xronomorph that allows you to create polyrhythms using shapes like in the video
It’s for pc
The Polyrhythm 7:9 is amazing🤩
How does it look like without lines?
9:06 ngl it was emotional, I was about to cry but the video ended soon later
The 1-:>17 looks like all the colours are chasing the white one, it looks so funny.
4:5 sounds so good
4:3 is amazing
5:2 sounds like a horror movie
Fico muito feliz por você estar presente
foi...
A Decision has happened 8:58
Last one sounds fire
Is there really any difference between the star and the polygon representations? The points move in different ways, but still it’s all the same, just another kind of visualization
It’s so cool
Yes
5 to 6 soudns very much like church bells to me. Not sure if church bells sounds different but the ones where i live sounds like it
I wanna see when the shape angles are ofset, instead of all meating in 1 point
Pls make similar video on polymeters
5/4 over 4/4
5/8 over 4/4
5/16 over 4/4
