I'm working as a school teacher of Computer Science for Year 6..9. Currently I develop an online collection of exercises for intro to programming. I have exercises: - on turtle, using my DSL with three commands: 4[100 r90] draws a squa

Yeah, I see your point. You want same alterations on different Roman numerals to look the same. (In my current system b9 over I and b9 over V look different.) I briefly explored this appoach: https://rawl.vercel.app/edit?a=b

In all cases of tonicization I decided whether to notate a brief tonic change or not (piece by piece, case by case): https://rawl.rocks/s/applied/chain_of_dominants You can always manually "probe", minut

So here I stand with dilettantes :) Being a jazz college dropout, I stopped building around standard notation when after two years of training - and I started learning piano at 25 - I still didn't get any fluency in instantly seeing ha

It's rainbow if we skip coloring 1 and 5 and color them with grayscale instead. Here's the question. If we can allow one color not to be "colorful" (chromatic), what pitch would that be? It's the tonic (pitch 1). If

Fair point. In my approach I got very dense yet readable information density on the screen. Eg. the entire Mov. 1 of Moonlight sonata is a single screen on my 16" Mac, yet all tonal effects are there, visible: https://rawl.r

Yes! hooktheory was my main inspiration over the years. One downside of hooktheory is that it's a reduction which someone should make for you beforehand. That is: - it's losing information - if no one analyzed a song yet, there&#x

They are actually similar by circle of thirds. They go as 1-3-5-7-2-4 over the rainbow. This makes main triads be smooth gradients instead of random three-color flags. 1 and 5 pitches are neutral because: - they are neutral (a hollow toni

I just wanted to revamp the good old Turtle to introduce my 11yo students to "repeat N times" loops. I'll get them lost at the angles' math for sure, but worth a try.

my favorite paper on analyzing chord progressions so far is this seemingly niche comparative study of five metal genres: https://pure.hud.ac.uk/ws/portalfiles/portal/58172029/Boddin... it shows which cho

Btw I'm making an interactive music theory course right now. I'm 2 months of polishing away from being HN-publishable, but I decided I'd share at least in comments. https://rawl.rocks

Your game has inspired me back then to create a game on quickly finding isomorphic graphs. Since then, I haven't created any other game in 10 years. So thank you for a powerful stimulus! https://vpavlenko.github.io/fluf

I've recently tried it on 1:1 calls with ML/backend engineers and on a workshop at our local hacker space for 20 people and I've got so much positive feedback that I've decided to share it here. If you follow this tutori

I have a detailed write-up in this thread: https://x.com/vitalypavlenko/status/1771820942680830417 Basically, you can somewhat see chords in sheet music. Like, you can easily see a C major chord in a treble clef.

the main problem that i'm solving is that a standard notation mostly obscures structure. it's good for sight reading because people use it (like QWERTY or Chinese characters), but it's a suboptimal way to make underlining str

that's a great point. i'm making my alternative https://rawl.rocks/ which does exactly that: a relative color-coding, starting from the tonic aside from that, I make a library of structures used in Western music (

Thank you! For me, it's not a fear of failure. It's a fear of meaninglessness. I feel like the culture where people generally running around and reaffirming each other that "studying anything from the past isn't necessar

Great to hear! I've spent last two years doing college-level piano studies (pre-conservatiorum, i.e. nominally Year 8-9, was more like Year 4-5 because I lacked any childhood piano background). Sadly, my program wasn't great in ma

Thanks for asking! I went to music theory specifically because I didn't want to produce anything before I analyze enough music (like, thousands of compositions). That is, I didn't want to talk music and do marketing on my composit
