Instead of using a preset Introduction, you can create your own intro by playing keys in a see-saw motion.
To play an intro that uses this style, play chords IIm and V7
anywhere you feel like it in the See-Saw.
Using the Key of C as an example, just start with the Dm chord and end on the G7 chord.
In other words, using Dm (IIm) as the start of your descent of the see-saw, you would play until you reach the G7 (V7)
