I'm 45 and started with an acoustic guitar in 2005 after years of guitar hero. I've been off and on and off again have a fender starcaster with an authentic stratocaster neck.
I can play songs and read guitar tab, mostly. But I have several serious shortcomings I want to address.
Strumming - specifically alternatating up, down up up up down etc,
Learning the notes
Basically I want to smoothly play in time and advanced strumming. I also want to progress to soloing over looping chord tracks. I'd love to just play a back track and hit notes that sound good.
I enjoy being able to dive into a tab and make it sound like the song. I just want to get better and am trying to maximize the little bit of practice time I'm putting in.
FYI mostly self taught from videos and books. I did take one set of lessons years ago.
