The Church has consistently taught that humans seek out the true, the good, and the beautiful. Artists, musicians, composers, actors, etc. have a special place in helping us discover all of three, especially beauty, in the created order. Benedict XVI says this, "if we acknowledge that beauty touches us intimately, that it wounds us, that it opens our eyes, then we rediscover the joy of seeing, of being able to grasp the profound meaning of our existence."
As a musician himself (pianist) the Pope understands the importance of such truths personally. We should listen closely when he speaks about it:
“Beauty is the glow of the true and the good that flows out of every ordered state of being.” - Joseph Pieper.
