Regarding my nails that used to haunt me, I have been back at the guitar now for 2 months, but have not practiced as much as I wanted to.
One thing funny is that I have not needed to use artificial nails. I guess it has just been a lucky streak and been careful with my right hand. The nails I bought were the Alaskan and Fred Kelly's. I see both will need some shaping if I need any, but I am unsure of my preference until I try them. I just thought, I have been keeping my nails on the short side as I have more control after not playing the guitar for years. I will give my humble opinion on the nails once I need them.
At this point I feel like a beginner reading music, but a few hard pieces are starting to come back to me. One I loved as a teenager was Classical Gas by Mason Williams and I have his exact rendition minus the orchestra. I have the original arrangement, notes with tabs, from the center page of the magazine the Guitar Player, April 1972, wherein Mason Williams adds a comment to the two pages that include the music. At one time I had this piece down pretty good, but now I am struggling with it. Parts keep popping from memory, but it is not all there yet. I do need a lot of simple sight reading practice.
