Q: Do you think that I should learn sheet music? I already know a lot of music theory, and music sheets kinda confuse me
A: different industries use it in different amounts. unless you are getting into a classical orchestra you probably won't need to know every little detail about everything, but in general it would probably be cool for you to learn how bars and barlines work, how rhythms work, and also learn about chord symbols. just so you can talk about things with your friends and co-workers a little more clearly
