That's a great article! I definitely like diving into things and trying them for myself. They make much more sense to me.
My boyfriend and I are having a sort of debate about this. I started learning guitar recently. He wants me to sit down with chord family and note progression documents and learn things A, B, C, and so on. Instead I just learned chords I needed and am adding in chords as I need them, so I can play songs. I can already play several songs, but I can't go A, B, C, D, E in a row. He thinks that's "wrong". I think I am having fun
