A.H... what it mean?

[x3roXL]

What does A.H. mean? I guessed it was something to do with harmonics... but I could be wayy off.

artificial harmonic... i just take it as a pinch harmonic.. i think thats what it is...... in fact im prety certain.. but i have a habit of being wrong.... so wait for some verification.....

n.h. is natural harmonic...
a.h. is artificial... (pinch..)

How do you do that?
