Many think of YouTube as a time waster, but really it’s a treasure trove of guitar knowledge (and the occasional cat video). You can learn so much for so little by just logging on and searching a topic you’re interested in. Want to learn the Mixolydian scale, how to play an A chord, or what the circle of fifths is? No problem! Between learning, entertainment, and reviews you could binge watch guitar videos for days.

Like anything that’s free though, it helps to know where to start, to cut through channels that aren’t so great yet, and to find out what’s helpful. Check out these five YouTube channels for guitar players.
