There is also a thing called tapped Artifical Harmonics. Really awesome for those A.H. melodies. Really easy to do and great for showing off. :D
Take the idea of how to play artificial harmonics regularly by picking the string while touching the node with your thumb. But with this technique you lay you thumb on the node beforehand, then tap with the other hand. Produces a series of A.H.'s when you tap the line you want to play. A tab will look like this:
e:--T------T------T-----T-------
B:------------------------------
G:--12(19)-10(17)-9(16)---------
D:----------------------10(17)--
A:------------------------------
E:------------------------------
*(A.H pitch that is sounded)
Notes: You'll have to lay you thumb correctly for it to work. It takes some practice just like when you started playing Artifical Harmonics in the first place. Have fun!
