Nevertwenty – Play along with any song using real-time chords

It's an intuitive tool specifically designed for practicing musicians. What's the magic ingredient, you ask?

Hey there, Hacker News community! I've just brought my dream app to life, and I'm eager to share it with you all. At a glance, it might seem like a search engine, but it's really so much more. It's an intuitive tool specifically designed for practicing musicians. What's the magic ingredient, you ask? The app shows users critical musical details about any song of their choice - but that's not even the best part. The real showstopper is that it can unveil the underlying chord structure of the song, which enables musicians to play along, learn the song, and anticipate the upcoming chord sequence in real time. I'm continually looking to enhance the player features, so your feedback is more than welcome! I've recently incorporated a feature allowing users to adjust the beats per minute (BPM), and now I'm in the process of adding a tuner as well. Let's hit the right notes together on this one, folks! Looking forward to hearing your thoughts. Only works on desktop. Working on getting mobile working and compatibility for Safari. Built with the latest nextjs. react, node. Am pretty satisfied with the software stack I used. I wasn't familiar with nextjs but as an experience full stack developer, I didn't find it too difficult learn and actually quite pleasant to use as my feature set grew. The biggest application limitation right now is the not perfect timing of the chord preview and bpm speed. Ideally the animation of these components should be perfectly correlated with the beat. I'm working on a betting timing implementation. Cheers! -brandon

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Heya HN, I've been working on a reddit-like platform as my primary side project for the last few years. Doing a (very) soft launch today, mainly because I want to use it to encourage discussion of alternatives. How non.io works: 1. Free to browse, paid to interact. 2. Minimum subscription is $2 (though you can choose more). I take $1 to run the servers, everything left gets split evenly between everything you upvote that month. It's a simple model, but I hope it's a better one than the freemium model we've been relying on for the last few years. Fundamentally I feel like any ad-supported…
