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!
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.
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
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
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
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.
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 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 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?
@@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
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
Interesting to see when visualized that there’s a line of symmetry on the 2. I found that as a tool to help keep track of where I am in the poly rhythm as that the first half of the pattern is mirrored to itself
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.
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.
This is incredible, thanks! It would be really cool if you could include the percussive/drumming sheet-notation along with each exercise. This would help students to understand the visual, written notation as seen in a book. It would help by associating what they hear with the patterns they read on the screen. Great content and new subscriber here; these vids are definitely helping me. Thanks again.😎

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. ".
4:37 you may notice that the red ball at the bottom of the screen is moving around, i'm pretty sure that it's because the spatial interpretation on your keyframes are set to auto-bezier. worst after effects default setting ever. i may be completely wrong though, and who knows, maybe you aren't even using AE lol
1. Isn't it really only the sequence of prime numbers that matter (though possibly with 1 in place of 2)? Surely 1 against 2 isn't really a polyrhythm because it's "normal" to divide a whole note into 2 half notes, into 4 quarter notes, into 8 eighth notes? Isn't what you're making when the numbers of beats aren't co-prime really closer to making chords rather than true polyrhythms? I wasn't following closely enough to see if the pitches you'd chosen were designed to sound good as chord intervals. Also, if a number is divisible by 2 or 3, like 4 for instance, then shouldn't it follow the normal conventions about the second and fourth beats being the weakest? (As for the other numbers like 13, it kind of gets complicated when there are multiple ways to divide up the number of beats in a bar doesn't it?) 2. It's interesting how the different rhythms start out in phase with one another on the "one", then drift out of phase, then come back together again. Which I guess makes sense musically. It can get a bit heavy on the one when there's a large number of rhythms but I think your choice of instrument helped to minimize that as compared to some of the more chiptune like renditions I've seen elsewhere. But I wonder how nice or awful it would sound if a few of the shapes were rotated by half a point. Or maybe one pair could be aligned together on the one but a third rhythm could be aligned with some other non-first beat of either of first two rhythms? 3. These videos yourself and others make always seem to play exactly the same note when a circle hits each point on its polygon. I wonder what it would sound like if each shape had its own melody that was just a little more complex than a single pitch but not much more complicated and still something that's easily codable using a simple algorithm. I wonder if that would make some of rhythmic combinations which presently sound awkward to my ear become more palatable. 4. When you initially said stars that wasn't what I was imagining. But your polygons with bent sides retain the quality that the beats always proceed as adjacent points around a circle, which wouldn't be the case if you'd used true star polygons like pentagrams.
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
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
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.
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

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 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!

shouldnt the dimensions be 1/y:1/x?
actually no wait, you explanation makes sense because (1/x)/(1/y) = y/x
I think there's a metaphor for the tritone being the most dominant sound in a cacophony of noise.
Fr
I think the stars are really effective, visually!
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.
6:00 The fact you chose the tritone of all things on this exact polyrhythm
an alarm sound

i love the final design and for what ever reason i thought i heard E before the 17 star got added-
I love how you built up to that tour de force polyglot polyrhythm. Chaos that is completely coherent, symetrical, and orderly.
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.
5:2 is pretty neat sounding
The use of the tonic fiths dominants and octaves majors and minors for the different ratios are not lost on me.
