Scales on Fretboard

Creation of an interface to learn scales on a fretboard

What's the goal?

I'm musician since I was a teenager. I play bass guitar and sometimes I like to pick my acoustic guitar or my Ukulele.

The problem I have and I try to solve with this project is my capacity to learn scales. There are a lot of courses online and I have several books with exercises. I also took some courses with a friend to learn the basics. Even with that, I cannot learn scales easily.

So I decided to create a web interface that allows me to select the scale I want to learn with the instrument I want and that gives me the full scale on a dynamic fretboard.

This project was designed to make room for new features. I will add them when I need it.
