Some people enjoy concerts more if they get involved with the music beforehand.
One thing that helps many people is listening to the music before the concert. This can be a lot of fun, too. Find a recording of one of the pieces, and play it in your kitchen, or in your car, or just sit down and listen. It might also increase your enjoyment to read a biography of the composer, or find out more about the performers, or look into the musical style or historical period. But more and more concertgoers are finding that they can deepen their experience by making friends with the music before the concert.
