Show HN: I built a music theory course with games and spaced repetition

https://www.gitori.com/themes/music-theory?showTheoryTour=true
4•udit99•3h ago
I’ve spent a year building a theory learning path that starts from scratch and goes all the way up to topics like Secondary Dominants and Borrowed Chords. It uses a combination of games, interactive lessons and spaced repetition to help you understand and remember concepts. Not just learn something new and forget it in a few days.

I’m trying to figure out: 1. Is the progression logical? 2. What am I missing that you’d like to see in there? 3. Where does it get confusing and could use more clarification?

Nice job. Some Feedback:

The AI‑generated images for the Circle of Fifths don’t make a lot of sense - why are there blurry Japanese kana/kanji on them?

Clicking on the “Guitar” dropdown in the navbar doesn’t do anything. The dev console shows this error:

  TypeError: Cannot read properties of null ('email')
Personally, I'd recommend doing some more manual testing before deployment. Remember to test all the paths twice (logged in and logged out).

Whoops! I’ll try and recreate the issue. Thanks for the tips.

The air particle visualization is really cool! However, I don't hear anything. I'm on chrome browser in linux. It wasn't clear how to get that to work. Thx
