Hi. I have an acquired brain injury, so it is quite hard to follow lessons, but I have been working hard on my guitar lessons for two years. I bought the Blues Slow Solo Construction Kit, which I think is great. The idea is perfect for a person with a brain injury. But I cannot understand how it exactly works? Griff says in the Introduction that you can use licks in one position, but don’t swap positions (eg do not swap position one lick 2 with position three lick 2). That’s ok, how do you move from one position to another position (1-7) if the licks are in different keys? It's probably because of me, but I find the instructions are not clear. Thank you very much for help by everyone.
