My first web app trains your ears

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,…

In plain words

Earbuilder is a web app that helps musicians develop ear training skills by playing two notes and asking users to identify the interval between them.

    Hello HN, I just released this music theory and ear training mobile app for guitar which I've been working on for a bit more than a year on the side. The idea was to make something for the eternally "intermediate" guitarist (myself included). There are a lot of beginner apps which rely on learning songs, toolkits which give you a bunch of stuff with no explanation but not many in-between apps to actually learn and practice more generic and somewhat advanced stuff. The app contains short lessons, recaps and most importantly challenges (visual, audio and pure theory) along with a very complete…
