I am in Rock 1 but I do not know if I'll touch reading again there

Every GT lesson with a musical example has music notation along with it. All the lessons in Rock 1 & 2 will be great examples for you to practice on. And especially since you have Anders playing the examples so you know what they should sound like.

You might also enjoy working through these simple melodies. I have some in the old GF1 starting here.

And some in my classical section here.

Also, the internet is a treasure trove of public domain material for practice. I enjoy reading through Bach's inventions a couple of times a week for practice.

Hope that helps!
