  • As part of 3blue1brown's summer of math exposition #2, I decided to make a crazy video I've always thought about making, exploring the interlocking nature of prime rhythmic cycles. For 10 minutes of just the music and no commentary, see • The Rhythm of the Prim... . For the making-of video, see • The Making of The Rhyt...
    All the music was created using the SCAMP libraries for computer-assisted music in Python: (scamp.marcevanstein.com/ ), while the animations were done in Processing (processing.org/ ). I plan to produce a making-of video in the coming weeks in which I run through the code.
    If you like this kind of thing and are interested in learning to do it yourself, consider taking my course on Kadenze.com, which will guide you step-by-step in getting started with Python and SCAMP, and also helps supports my work: www.kadenze.com/courses/compu...

      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.

Unlike the video editor we've not heard the isolated sound pre-edit to be able to be reminded of the sound of each variant from a clip of a couple of seconds... It's worth the editor bearing in mind that viewers will be hearing these interesting sounds for the first time.

    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.

      @SmileyMPV Рік тому +5

      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.

  • @eli0damon
    @eli0damon Рік тому +366

    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.

      @@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

    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. There are some impressive implications in the math of the harmonic series if you can build intuition around it. You could hypothetically use the log scale structure of the harmonic series to teach times tables with ear training. The kids would likely make weird errors around octaves and powers of two...

    • @marcevanstein
      @marcevanstein  Рік тому +83

      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.

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.

    Many years ago I had much the same idea, and made a song out of the first 17 primes running through their rhythm for a few minutes. I then had a musician friend choose samples for the soundscape. The end result was less about the rhythm of the primes, and more an evolving soundscape with a difficult-to-define rhythmic pace, but it was a fun project!

  • @inciaradible7144

    This is really cool! Considering there's sort of an upper and lower bound at which rhythm breaks down as far as human perception is concerned (I think the lower bound is around 33 bpm), you can choose to simply work with a finite number of primes and create a lot of different arrangements.

    I perceived an almost horizontal and equal three-based pattern which simply kept emerging in a new
    timbral space, which seems independent of remainder of three rule. I also imagine I hear an accelerating
    clave, sometimes swapping polarity between 5:3 and 3:5 which I guess is a consequence of remainder
    distribution too.

    Have you considered making a mapping that is calculated modulo some frequency? so that if a prime's frequency would be below a certain threshold, the value "wraps around" back to the difference between the threshold and the frequency? This would allow you to play your music indefinitely without going so low that the value is inaudible.

    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).
    I ran this with the numbers 2,3,5,7, & 11 and got this: drive.google.com/file/d/1-YIUfIMMKZDjd3G_cjUr_0c9ng_OkfgB/view?usp=drivesdk

    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

    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.

    I did something like this with the regular harmonic series, so that the 2s and 3s form a sort of bassline. I played the series "backwards" so when it gets down to zero, there's a big chord containing all the notes. Then I played a couple of these, with different fundamentals, offset by about one measure, so you hear two of those chords one after the other at the climax.
