A different approach to intonation training
Hi guys; Over the weekend I've created this using Claude Code. It's an ear training app destined to teach intonation and intervals to not so talented musicians like me. I spend many year playing guitar without a clear feeling on what intonation really was. It was after some string tuning exercises that it clicked for me. The freq sliding into the right place and feeling the correctness. I hope this app can helps other to feel that for the first time, or to increase the recognition of less common intervals. Any feedback is appreciated.

Hi HN, I've been taking guitar lessons and one thing that is recommended to most musicians is ear training - where two different notes are played and you must identify the number of steps between the notes. My app, Earbuilder, should help with that process. You can find it here: http://www.earbuilder.com/ It's my first web app, and my first real foray into JavaScript. You can take a look at the source and you'll see that it's pretty poorly structured, but I've picked up a book and hopefully things will improve with my second web application. Please let me know if you have any comments,…

Hello HN! It seems there has been an influx of MIDI projects as of late. I myself also got inspired to work on one last January. I had become frustrated in not being able to read my old sheet music without counting the notes mentally. I thought there had to be an easier way to learn them, I surveyd some apps but none of them felt right to me. So I decided to build one myself and learn some music theory too. I'm quite happy how it turned out, in the end. My sheet-reading has improved substantially although playing and remembering notes is two different things. It works best if you use MIDI…

- IRI replaced my premium workout app with vibecodeDec 2025 · strengthquest.lovable.app · ▲9
I was going through my app subscriptions and realized I was paying $15 for a pretty good workout app, which seemed a bit high to me. As a software engineer who is also well versed in claude code, I realized that I could likely vibecode a very similar app, or even build something more to my liking. I challenged my self to build something roughly equivalent this afternoon. Workflow was: start with a detailed spec from Claude code describing many of the features common in workout apps. Then paste this into lovable to have it build out the initial mvp. Once that was built, I used claude code…

Saw the remotion claude skills launch earlier, and honestly even though I was surprised how decent some of the results turned out to be I ended up never trying it out with claude code because I knew I'd have to setup remotion, bundler etc and if I was already doing it once I thought I might as well turn it into a site where anyone could just write messages and get a video without any prerequisites. I also know Claude Code is not something everyone has and setting up remotion is a pain. And one of the biggest lessons I learned from this whole experience is that Opus is actually not that good…
