My sister is amazing and brought my guitar back across the country to me when she came back from visiting home. I haven't played in forever and never took lessons, but here's me not totally failing to remember the bit of Malagueña that my dad taught me.
@lewlepton honestly, it's just rote memorization and muscle memory
I'm working through the Justin Guitar lessons on YouTube to hopefully actually learn how to play. The videos are pretty good and well organized. And free!
There's an app that will track progress and has paid songs you can play along to but also a lot of free exercise. I may pay because it's his full-time gig and I'm liking it.
