Great job learning the G major and E minor scales, they're super useful to have. And they will really help you. When you go to learn other scales, you can have a scale in any letter of the musical alphabet. So a major B major C, etc. up to G. A major, you could have a minor, B minor you could have, we talked about sharps, you could have F sharp major F sharp minor. There's so many to learn from.
Just pick one, one at a time and go from there. There's a lot of resources online for those sorts of things. If you're wondering where to start, I would just start with the scales that we've been learning so you can type in a pentatonic scale, or a major pentatonic scale and practice that or a minor scale and that sort of thing. Now that you've got some scales under your fingers, let's head over to the next module, where we will learn about the E blues.
