The Distant Song

Ever since you were a young girl, you heard something that no one else did; a single clear note coming somewhere from the west of your home rang constantly but gently into your ears. The tone changes pitch from time to time for reasons you cannot explain, but over the years you have gotten used to its constant song, and have even learned to navigate from place to place by using it as a compass. One day, not just the pitch changed, but the key as well. Soon after the song warbled for the first time in your life. Worried, you felt compelled to finally leave your home and follow the song to its source.   Notes of Navigation: Thanks to years of using the distant song to get from place to place, you rarely become lost. You always know the source and direction of the song, allowing you to navigate easily. You can not get lost while through normal means while you can hear the song.
