Hello again, Mr. Dime
Congratulations on joining us and we all look forward to hearing your progress.

Bonnie Shaljean and Richard Bridge have given you some excellent advice ande I am pleased to see that you have reduced your practice sessions to something which most of us would consider more reasonable.

The comments about "mental practice" and visualisation are absolutely correct. I was taught this in Osteopathic College and the system certainly helped many of us to get through our exams.
Of course the changes in your method of holding your guitar will feel strange. I have just the same thing when I am learning a new technique to adjust a joint. Practice, with visualisation when no patient is available, will train the muscles into a new habit and ability to do a particular job.

Think how long it took to learn to drive smoothly, without setting off like a kangaroo! How long did it take for your brain and your muscle to learn to ride a bike?
Best wishes and keep us informed
Colyn.
