there's a thing that comes up among people who are self taught with music or whatever people who do that are said to have "gaps in their knowledge"-stuff people with more formal education learned in school about proper technique or whatever. i always think that's a little strange to say because everybody has gaps in their knowledge, just the people who studied in school have all filled the same gaps. how do you recommend self taught musicians (like me) fill in those gaps? i kinda think if you pay enough attention to how other people do it, and you are somehow very relaxed yet focused, you can pretty much do whatever
really it's just like learning to read. the words don't change if you can't read, but reading/writing will help you communicate with the wider world. i'd say just get some song books. learn to read them. now that the internet is a thing, you can pretty much just look up everything you need to know 1 by 1. but i think song books would be the best thing, not only to become literate but it will probably introduce you to more songs and make you a stronger musical person in general
