I am 89 years old and my guitar is older than I am. It was made around 1920. I was able to pick out a tune one note at a time as a kid. Then WWII and the Navy came along, and then a family. Now I have the time, I can't play golf all of the time. I read notes well enough to play a Casio keyboard for my own enjoyment. I may have a problem. I had the guitar repaired and the technician tuned it one level below the standard. He was afraid the correct tuning would be too much of a strain on a 95 year old martin type guitar. Everything sounds OK to me but I am not sure how this will affect future lessons. I guess I will find out.
