There’s no need to study. The music will speak for itself. Just come and enjoy! Over time, many frequent concertgoers do find their enjoyment is deeper if they prepare for a concert. This can be simple, like reading the program notes beforehand; or it can be more involved, like listening to recordings of the music to be performed in the days before they attend a concert. You know yourself best, so if research interests you, go ahead and follow your curiosity. But if studying isn’t your thing, there’s no need to be concerned about it. Just listen with an open mind.
