I am a 17 year old rising senior in high school, and over the past year, I have fell in love with music and would love to learn how to play guitar and maybe during college start independently writing and recording my own songs. My problem is I have no idea where to start. My dad used to be a somewhat prominent drummer, and he also sort of plays guitar, but I was wondering if anyone has any tips outside of that as well. If not I'm perfectly fine just talking to him. Also, I'm not sure if this is the right place to ask, but does anyone have any advice for doing my own thing independently and building some popularity eventually? Any advice is well appreciated! Thanks!
