Tony does an excellent job of explaining how to do the task at hand, and the video shows how to accomplish the task with close-up footage of his hands. If you are a slow-learner (which I have found I am when trying to learn guitar), you can back the video up and watch it as many times as you need to for full understanding. I have to stop and start videos so I can write appropriate information down to help me understand what I am supposed to do. (I have to use multiple senses to get it -- so I watch and listen, write it down, and then use my notes to back-up what is on the video.) I am a total newbie -- knowing nothing, so it is slow-going for me. I can't say I have mastered anything yet, but the course material is well-designed and well-presented, so with patience and persistence, I think I will ultimately begin to be able to master skills.
