1. Select "Songs" from the Menu.
2. Decide whether you want to sort through all songs, or by individual genre. If a genre, select the genre first. e.g. Country, or Rock. If not, just proceed to the next step.
3. Below the selectable genres Buttons which present you'll see selectable sorting Buttons, one of which is labeled Difficulty.
4. Now select Difficulty from the already presented Sort sub-menu Within the category selected Songs will present in order of increasing difficulty represented by guitar icons. The more guitar icons, the greater the complexity or difficulty of the song. These are just an approximate guide.
Where you're at, my suggestion would be to start with one or two guitar difficulty songs. There is no half star rating, and you want to start out by reinforcing your recent success. IME three stars will currently present a formidable challenge to your skills, and the way the rating system difficulty is assigned by individual instructor perception can vary considerably. Unless you're feeling confident and exceptionally tenacious, you won't want to tackle a three which is possibly closer a four but which has been rated a three due to the absence of a half incremental rating in conjunction with that instructor's relative perception of easiness.
GL. Have fun.😀
