Good God. Learn some basic theory so you can do this more easily in the future; for now just experiment and see what works. Don't just ask the most vague, generic question possible.

@reedplaysgeetar: Minor thirds (an interval) are one and a half steps apart, and you use such intervals to build chords, commonly in a "stacking thirds" approach.
