>>48493580>Sheet music is used anytime you deal with real instruments (including vocal chords) in the professional music industry.well, no. a lot of people are self taught. you're maybe talking about, again, classical music, where you're either playing with people, or you're playing or singing very complex stuff, and you can't improvise outside of very specific cases.
why would a non-classical guitarist need to know how to read notes for example, when they mostly use chord names or chord charts ?
