My YouTube channel is the main place for all my teaching materials.
There’s a big (and constantly growing) series called Guitar Song Essentials that gives you all the elements you’ll need—chord shapes, strumming patterns, picking ideas, all the little twiddly bits and stylistic details—to create an authentic performance of loads of songs on acoustic guitar. I add at least one new video a week. Fridays, since you ask. Subscribe to be notified 😉
If you’re after the basics of guitar technique, take a look at Guitar Basics, a series of gentle introductory ideas to help you get your playing off the ground.
More advanced? Browse through Must Know Guitar, a playlist of more advanced ideas including info on learning the fingerboard, various alternative tunings, and that sort of thing.
There’s loads of other stuff, but the Soundbites series is especially popular: it’s a step-by-step intro to music theory aimed at beginners, so if you want to get to grips with scales and chords and keys and all that sort of thing, then that’s a great place to start! I’ve linked to the entire series in the menu at the top of this page, too.
