How do you do a harmonic chord? I don't understand them, and I would like an explanation.

Thanks in advanced.

well, you first make a chord, say an "A". then, count 12 frets up from each of the fretted notes in said chord. then you tap the fretwire at each of the spots. this creates a tap harmonic, and when you hit them all one after another creates a harmonic chord.
