 ## Demonstration
 
-   (Video coming soon)Check out the video below for a Legend of Zelda music demostration.  In the video, an Arduino Nano outputs two voices. The arduino uses a vibrating motor as a percussion instrument, and an RGB LED to add some fire to the show.  The delay function is not used at all :)

 ## Advantages
 * This Arduino Library makes an Arduino board play music in the background while running your program(Assuming your code doesn't have any delay).  
   * **So you can view the Serial Monitor, display stuff on an OLED, and read buttons while this library plays your music in the background**
