Pi Bikers of Sappho Version 1, Poly Rhythm Beat

First of several pieces I made very quickly for Pi Day 2024, because my brain decided early evening of Wednesday for me that I just like totally needed to upload several videos for Pi Day since I had variations of the music ready
What does this have to do with Pi Day? Well, all the notes in the song last for either 0.318, 0.159, or 0.477 seconds (which is 0.318 + 0.159)... 0.318 seconds is the length of the period, rounded to the thousandth place, for a frequency of π Hertz (specifically π rounded to 3.1416). 
The notes are also grouped in patterns lasting for 1.272, 1.59, and 1.908, which are all multiples of 0.318 and (very roughly) correspond to the periods of frequencies of π/4, π/5, and π/6 Hertz.

As a part of making a video I could be happy with, I made some art... also included having a hexagon cloud-like shapes moving across the screen (done entirely using "Size, Position, and Rotate" tool in Shotcut), and multiple slight variations of the same background picture to constantly cross-fade between (again, with Shotcut)

So here's what happened: I have too many side projects in my music making and sound synthesis... and by that I mean my side projects have side projects.

Nothing particularly special about the notes themselves: all sawtooth waves, all either C3, E3, G3, or G3sharp tuned on 440 Hertz-based scale. Each note's fade-out was done with Audacity's "Studio Face Out" tool, which I've come to like enough for basic fade-outs that I even bothered to make a keybind for the tool!

More of interest is the poly-rhythm patterns for this song, which I will attempt to represent in this description as best I can:
█Pattern 1 -- 1.908 seconds long: (E3, 0.318 seconds) → (G3sharp, 0.159 seconds) → (G3, 0.477 seconds) → (C3, 0.318 seconds) → (silence until reaching end of this 1.908 second long pattern)
█Pattern 2 -- 1.59 seconds long: (silence, 0.795 seconds) → (E3, 0.318 seconds) → (C3, 0.318 seconds) → (silence until reaching end of this 1.59 second long pattern)
█Pattern 3 -- 1.272 seconds long: (C3, 0.159 seconds) → (silence, 0.477 seconds) → (E3, 0.159 seconds) → (E3, 0.159 seconds) → (silence until reaching end of this 1.272 second long pattern)

each pattern played on its own track, and each segment started immediately after the end of the previous respective segment, thus making the usual overlapping of a poly rhythm song.
