If you’re not sure, start with the path for your level: Beginner, Intermediate or Advanced. They’re at the top of the Learning Paths page under Start Here.
Already know what you want to work on? The rest of the page groups paths into Beginner Friendly, Build Your Technique, Theory and Improvising, Styles and Genres, Artist Studies, and Gear and Recording, so you can go straight to things like legato, modes or jazz.
