Working on https://chessnawk.vercel.app/ – a set of auto-grading tasks for middle school students learning programming. Comes with Robot, Turtle, HTML/CSS (pixel diff tasks) and a …

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, us…

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 th…

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 …

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 …

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 th…

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 tona…

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 inf…

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 pitc…

I designed a relative piano-roll-based music notation. I used 12 colored arranged in a specific way to make visible the main effects and oppositions of Western tonal harmony. The t…

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/Boddi…

I'm a happy vibe coder and I write 100% of my source code via Cursor IDE by prompting in English since August 2024. My tech stack is React-Typescript with simple Firebase. I'm a se…

What are you working on? Any new ideas that you're thinking about?

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.ro…

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 sti…

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 …

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…

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 …

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 s…
