Greetis! I've recently gotten bored making metal music and want something I wan't to enjoy even though I May not end up playing Death or Nevernire on it. I wan't to take some online courses and I wan't to learn some chords and how the relate to eachother inorder so sound good and harmonize. Also how to take an F and a C or whatever on different on the neck. Essentaly the different positions for the same chord.I'm self thought and in the future. I also wan't to know some theory. I can play a lot of metal, rock and I really I have some understanding of what online teachers on youtoube are the talking baout but I really wan't to know bit more. Please help me advance in me knowing what I'm doing when playing guitar. Books, online lessions, PDF's e.t.c. are all welcome. Have a great deay Thank you very much. I Am Swedish so pleasy excuse any grammatical errors, thank you.
