How to Use FretMonster

Curious about this tool and how to use it? Check out the video above! It gives a walkthrough of how FretMonster works, and the various ways you might use it.

In short, it provides a map of the notes on the guitar fretboard based on whatever key and scale you specify. For me, this tool was invaluable in helping me "see" chord shapes, scales, triads, intervals, and other patterns as they repeat on the fretboard. Here's timestamps of what I cover in my video:

Lessons I've Made That Showcase FretMonster

Here's a handful of lessons I've made where I made use of FretMonster while explaining the concepts at hand. Whether you're looking to brush up on your theory, or simply want to know where on the fretboard you can play a specific lick — there's tons of utility you can get from this tool!

How FretMonster Came To Be

Quite simply, I was eager to brush up on my web development skills (jQuery, in particular) and wanted a pet-project I could use as a guinea pig. I've always been a doodler, and drawing maps of the fretboard was a frequent hobby of mine back in college. So, I took those tendencies and turned them into a web-based project. This was back in 2014 or so, as chronicled by a few Dribbble shots I posted to my profile back at that time.

A few months later, I got things to a place where I was pleased with how things looked, worked, and felt to use while playing guitar. I've made some changes over the years (e.g. adding instruments), but the current version of the tool is largely the same under the hood. There are so, so many new features I'd like to add... hopefully one day I'll get around to them! In the meantime I hope it is of service in your guitar journey.
