RE: My old attempts in musical composition for classic guitar - 7 scores.
This is amazing. I loved your post. I compose music and most of it I know by heart.
I'm started to worry in case I won't remember how to play it in the future. Luckily most of my music is online.
Now and then I still read sheet music for guitar but I prefer to improvise.
It's never too late to resume playing guitar and at least you already have some handwritten music.
All the Best!
