Quite a few years ago I made an array of primes and then using bitwise math triggered midi notes in the same key as bits 3 through 12 or so turned on in the integers as the array was cycled through, the bits acting like the pegs in a music box. It played an interesting song. I also painted a picture with the bits of primes in a strip. Low bits at the top. If the bit were on I drew a small line on the screen down to about 24 bits or so. The ribbon of primes was ghastly looking, bizarre, never repeating. With the same algorithm if you painted all integers the strip looks like a pristine orderly mountain range, but the prime version was ugly looking. I looked to see if I still had a copy of it, but no, I'd have to do it over again.

The Sieve of Eratosthenes algorithm stops at 10 (square root of 100) in your example. The remaining numbers are all prime. Think about it: Any factor above 10 would have been found by a factor below 10 (for numbers up to 100). This is why the sieve is so powerful. If we were to find all the primes to 10,000 we only have to do the sieve to 100. Primes to 1,000,000, only do the sieve to 1,000. Etc.

Believe it or not but this optimization barely matters. To understand this, think about sieving the multiples of 2. You need to cross off half the numbers in your list. Now think about sieving the multiples of 101. This only takes 1/50th the work. This is where the real power lies in the sieve of eratosthenes. We find that sieving all multiples of the numbers 2,3,…,k in the numbers up to N takes (1/2+1/3+…+1/k)N=Nlogk time. All your optimization does is use k=N^1/2 rather than k=N. That only yields an optimization of 1/2. But it gets even better. We only sieve multiples of primes. This yields Nloglogk time instead. So as k gets larger, the optimization factor tends to 1 and becomes unnoticeable, let alone significant. There are even optimizations to the sieve of eratosthenes to achieve linear running time btw.

This is incredibly cool. When you mentioned trying a faster tempo, it made me think what if we increased the tempo steadily as the song is progresses. Primes on the small end would one by one turn into continuous rising tones that would eventually fade away as they passed out of the audible range, leaving space to hear the larger primes. And we could set an "equalizer" to make them fade soon if we wanted. We could also have the prime-pitch coding change in a steady manner, so that increasingly large primes would pass in and out of the audible pitch range and the natural tempo range at the same time. Using this moving window of pitch and tempo might prevent the song as a whole from blowing up or fading out.

I'd like to hear the undertones matched with the primes themselves and not the n-th prime. Maybe it wouldn't add much, but it might reveal some structure tonally as well as rhythmically.

Yeah, that's an interesting point. Often in just intonation we talk about tunings having different prime limits (e.g. 5-limit, 7-limit), meaning we only allow frequency ratios that break down into prime factors below that limit. I guess in this video, I was more focused on the rhythmic aspect than the tuning, and by going with the nth prime I avoided getting too low to fast.

@@droughdough If you were to write out this music, it would all be 8th notes, they are just at different pitches. With polyrhythms that's not the case, as each different instrument/voice would have to be written as a different tuplet (like a triplet, or quintuplet). Here's the easiest way I can put it: Polymeter means there are multiple meters (time signatures) happening simultaneously, but we keep the tempo and the note divisions constant. This means the different instruments do NOT start together at the beginning of each measure, and instead it might take a few bars for them to get back together. As an example, imagine a piano playing 3 8th note pattern played on top of a guitar playing a 4 8th note pattern. The patterns are different lengths but the same speed. Polyrhythm means it's all the same time signature, but the different instruments are playing different speeds (or tuplets). In other words, within the space of one measure, one instrument might play 4 notes while the other instrument plays 5 notes, but they always start at back together at the beginning of each measure. The patterns are all the same length but different speeds but the same length

It would be interesting to hear it where it speeds up logarithmically to keep the introduction of new primes fairly consistent while also fading out the volume of old primes over time to clear out the noise. Would the sound of it stay loosely consistent while also morphing in an organic feeling way? You could reuse the same sounds after a certain point since they would fade to nothing, so it should be able to be done forever.

There's the downside that you have to decide how deep to take your recursion ahead of time and then rescale your playback speed to make sense for how deep you went, rather than just adding in parts until it's a mess and stopping, but has the potentially interesting advantage that you can go arbitrarily deep and still have all the cycles line up in a finite amount of time.

What program did you use to make this? Because I'm doing a whole lot of CTL+C CTL+V in Cakewalk to make my variations. My theory has been that each prime number (P) follows the same rule. Starting at a high note, every time (P) reaches a new factor (^n), it plays the highest note. The tones go down the scale as (P^n-x) where n-x is greater than 0. This results in lower primes kind of crawling off of the song the longer it goes. If we follow this approach using the A minor pentatonic scale; P^n-0 = A7 P^n-1 = G7 P^n-2 = E7 P^n-3 = D7 P^n-4 = C7 P^n-5 = A6 ... So the first time you hear the note A6 is at number 66, because 64=2^(6) and 66=2^(6-5)*11^(1-0).

@@christopherrice891 I might not understand your question, but I'm afraid I'm the wrong guy to ask. I only have a passing knowledge of number theory, no working knowledge.

I love this!! Thank you for the clear explanations and for showing us the outcome! Nice!

Beautiful video, and strangely pleasing to the year. Well done!

its misleading to call this a polyrhythm, especially when you are letting it go to infinity this is more accurately a polymeter: different sized cycles on the same size subdivision. A polyrhythm is different sized subdivisions with one shared cycle length. Any finite polymeter is also a polyrhythm, but the cycle length of that polyrhythm is the least common multiple of all the parts; in the 2:3:5:7 example towards the beginning of this video for instance, you didn't even get close to playing a full cycle of the polyrhythm, as that'd be 210 subdivisions. So, what appears to be the 2 of the infinite polyrhythm is actually the 2 of the polymeter; the rhythm that has 2 evenly spaced hits over the full cycle length is... well, infinite. you're not technically wrong to call it an "infinite polyrhythm" in the sense that the cycle length is infinite, but I am sure this has made some people think that polyrhythm is polymeter I find polymeter often more musically useful, and I don't want to detract from the cool math here, but polyrhythm just isnt the right musical term

This is brilliant. Wonderful.

I cannot describe how satisfying it was to watch this. Bravo.

This was so beautiful! I can't believe I just found your channel - as a video creator myself, I understand how much time this must have taken. Liked and subscribed 💛

Returning here 2 years after I first saw the video, I realised just now how much I have learnt. I am so grateful for your channel, everytNice tutorialng

I love ❤️ your creativity with math and music

This was outstanding. Thank you!

Kudos man. You kept it very simple and helped make the first steps in soft soft. Very Helpfull! Thanks!

I really like all the different scales and tempi you used for the prime numbers. I couldn't help thinking this could easily be a theoretical example to demonstrate synaethesia. Although there are some more prevalent forms of synaesthesia, practically any combination of sensory substitution is possible. I like to imagine hearing colours or numbers, tasting or smelling colors, feeling the texture of temperature etc. Most people goosebump or shiver in response to a sudden or prolonged decrease in temperature. These responses can also be elicted by shock, fear, horror, awe and other emotions which may also be evoked by touch, sound and music etc. Whilst it is still a response to temperature change, I occasionally goosebump and shiver when going from a relatively warm to very hot environment. Usually this occurs when going from outdoors, on a day warm enough in direct sunlight for me to enjoy being in the shade or maybe find a cool breeze, then getting into a car with no air conditioning that has been in full sun for a while. I also fall into the minority of people with a photic sneeze reflex; we really aren't all wired the same.

Absolutely fascinating.

This was fascinating, Marc. Thank you!

When a musician is also a math hobbyist, you get masterpiece like this

This is exceptional. The long mapping looks like an ocean at perspective.

at 3:35 my drum and bass vibes kicked in. And by the way this video is more scientific than students learn during their master classes in university, I guess. Cheers to you!

I like the way those rhythms sound!

Incredible production quality!

This got me way too excited considering it is almost 1:30 a.m.! Thank you, this was beautiful!

Absolutely fantastic video!

wow! What a genius, just the analysis is amazing but yet the representation of the concept and the animations and everything else is also amazing. Congrats!

I used to do this with a friend in 2009. Cute to see it replicated.

I love this video, very beautiful!

Absolutely fascinating video

Great work. Thanks.

Reminds me of a similar video years ago mapping the C-major pentatonic scale to the digits of pi, plus some backing music
