Instead of using a preset Introduction, you can create your own intro by swiping the black keys.
To play an intro that uses only the black keys, first set the sound to a Harp sound. The Harp produces the best effect. You then would use the finger tips from both hands to scroll across the black keys, crossing the hands over and over again in an ascending manner, and then repeat in a descending manner. It is suggested you do this at least 3 times before completing the progression in the descending mode.
You would then wait 2 to 3 seconds before starting play.
