Music is the art form that combines rhythm and sound to form a functional melodic line. Music itself transcends time, space, and cultures. Music can carry a mood without speaking any specific words. It can also be captured and recorded in a written universal language unique unto any other art form. The purpose of music is to provide expression and control moods in humans and animals alike. Music can provide a soothing technique for crying babies, and calm animals when they are frightened. Music is an antidote for emotion when words fail.
