lukehaason Music Theory for Programmers

I can't play an instrument, even after multiple attempts. The main problem for me was understanding the theory. When you start learning, you're expected to accept a lot of things at face value with very little explanation for why things in music are the way they are.

This article documents my own journey into understanding music through writing code and taking a first-principles approach. This enabled me to understand things like why there are 12 notes and why notes in the same key sound good. Hopefully, if you are in a similar position to me, this will give you a foundational understanding of music that you can reason about instead of memorising.

lukehaason Ask HN: Is phonegap/cordova still relevant?

I think Cordova is increasing in relevance. Over the last couple of years mobile devices have reached a level of performance that makes hybrid apps feel native. When you combine Cordova with Ionic you can create write-once apps that deploy to any device and have a native look and feel.
