Hi HN,

A few months ago I made this website called Treblekey.

Since I began learning how to play guitar and piano about 2-3 years ago, I've been looking for a tool to help me:

- learn how to navigate the guitar fretboard

- practice hearing and identifying musical intervals (ear training)

- other things I might come up with in the future

And I thought: "it would be pretty nice if there was an app with useful musical exercises for beginners", which is how I got the idea for Treblekey.

Feel free to check it out and let me know what you think :)

Thanks!

For the interval reference sheet, why not play the intervals right there? That would be a lot more friendly and convenient than jumping to a youtube video, watching a 30-seconds+ of ads, then listening to 1 or 2 minutes of song just to compare two notes. Also it keeps users on your page and they won't get distracted with your use clickbait videos.
