How do i make sense of the pipe organ

The pipe organ has so many bells and whistles that I need to have these described. Do I need to know how to play the piano first? You will learn about the keyboards, the foot pedals and those other pedals, as well as those tabs and drawbars. You will discover how to play loud and soft, what kinds of sounds you can make and even some easy music to learn. You are about to have a very fun experience with the King of Instruments.
