/* "He's A Pirate" / "Pirates of the Caribbean" Theme Song Playing
 * By Xitang 2016.06.27 
 * Youtube in Action: https://youtu.be/sjPAj1lXgtk
 * 
 * INSTRUCTION: Hook up Pin 10 to the positive side of a buzzer or a microphone, hook up 
 * any resistor to the negative side of a buzzer (to limit current & volume & to protect the pin), 
 * and then connect the other end of the resistor to ground pin. Upload the sketch and enjoy! 
 * 
 * Music notes of the song obtained from Easy Music (Great website)

 * 
 * Also would like to credit Musicnotes's "How to Read Sheet Music" Guide
