Music is the one art we all have inside. We may not be able to play an instrument, but we can sing along or tap our feet. Have you ever seen a baby bouncing up and down in the crib in time to some music? When you think of it, some of that baby's first messages from his or her parents may have been lullabies, or at least the music of their speaking voices. All of us have had the experience of hearing a tune from childhood and having that melody evoke memory or a feeling. The music we hear early on tends to stay with us all our lives.
