Shepherds often made up music. This is why composers of classical music very often wrote music which imitated the sound of the shepherd’s pipe. For example: in Mozart’s opera The Magic Flute the character Papageno, a birdcatcher, plays on his pipes. In the "Symphonie Fantastique" Berlioz wrote music which describes a shepherd playing his pipes, and a shepherdess far away the other side of the hill answering his call. Berlioz used an oboe and a cor anglais for this.
