Dammit! I was planning a math song! :D Man, this is awesome. You know how much I love gimmicks when it comes to music. It feels like you'd really love this song: https://www.youtube.com/watch?v=E36qMxXGo3A :)
As for the track itself, it's pretty awesome. It's mixed really well; all the different instruments are nice and clear. Some of the instruments sound a bit loud, especially the synth that comes in 2:08. I know it shows up in other places in the track, but it really feels a bit loud there. After you automate the volume down in the next bit, it goes back to sounding normal.
There's tons of cool rhythmic stuff going on here. I'm pretty bad at coming up with creative rhythms while I'm noodling around on the piano, since my basic rhythms are ingrained in my brain, but you always have these awesome syncopations that make your tracks really memorable. The only place where I think the rhythm might be a bit confusing is the synth that plays by itself at 1:09. When I first listened to it, I was caught a bit off guard, but once the bass and drums started coming in, it sounded much better and I'm pretty much used to it now. :P A thing I've noticed about having too much syncopation is that if you don't have any background instruments playing a steady beat, it gets disconcerting upon first listen, which is something I think tons of musicians ought to keep in mind.
Your melodies are getting much better. :) A few of your older songs have some off-key notes, but recently, your stuff has been improving a whole lot. It's cool to expand your range of musical abilities in any way possible; you seem to have B minor down to a cinch. The chord progressions of the majority of my old songs revolves around F, C, and G, and you can hear the lack of melodic quality when I tried leaving them. This one sounds great!
The overall atmosphere of the song is quite eerie. The breathy instruments, the thin pads, and those background sweeps at 1:02, 1:06, 2:40 contribute so much to the mysterious, somewhat creepy vibe of the music. Also, I'm not sure if this should be a loop; the intro and outro don't have that much connectivity. Still, I really enjoyed the song. You're improving a lot in your melodies and composition. Great work and good luck in school!
(How exactly would one express Pascal's Triangle through music? Hm...)
