Over the years I have looked at a lot of teaching/video sites that offer lessons on guitar technique. Some sites are better than others that is for sure. Not long ago I stumbled across JustinGuitar.com. http://JustinGuitar.com.
I can’t recommend it enough. Justin is an excellent teacher and his videos are clear, well-executed, and very helpful. He has a friendly easy manner and the site offers information about technique, but also about simple logistical things a beginning performer may not think about. His videos, supported by information on his website, are free and cover a wide range of topics for beginners, intermediate players, master classes, blues techniques, jazz, fingerstyle, folk … there is great information accompanied by practice backing tracks for most lessons. Take a few minutes and explore the site. Watch one of his videos and I think you will be hooked.
