Artificial Harmonics are a way to get harmonic resonance from a string while it is fretted. Like natural (open string) harmonics, artificial harmonics involve dividing the string into an integer multiple of separate resonating pieces, by placing a finger on one of the pivot points or "dead spots" and sounding the string. The big difference is that since our left-hand is busy fretting the note, we have to use the right hand to do so.
Artificial harmonics are usually indicated by a * before or after the fret number. Sometimes the actual pitch of the sounded note is written above the tab. And sometimes the * is simply above the tab.
E *
The above is a natural harmonic created by using the left-hand as a pivot above the 5th fret. The next note involve actually fretting the 12th fret, but using an artificial harmonic to get that same note. We are given the actual pitch that should be sounded's note name, but we don't know exactly which harmonic this is. It could be the 2nd, 4th, or higher. The final note is an ambiguous artifical harmonic - we know we are getting a harmonic of the 12th fret E note, but we don't have any information about which harmonic to sound.
= Picking Technique (Pinch Harmonics) =
This is what is most commonly referred to when saying "artificial harmonic". This technique uses a slighted tilted picking hand to allow the thumb to touch the string as the pick plucks it. The thumb acts as a pivot point to create the harmonic, just like the left-hand finger for a natural harmonic. And again like natural harmonics, you want to lift the thumb off the string as soon as the harmonic is sounded. Usually its it's just a normal picking motion, but you add the thumb.
It is possible to use your right hand index finger (or another finger) as the pivot point; however, I find this is more difficult. For my pick grip, my index finger's nail would likely touch the string, which doesn't work as well as the flesh of the side of my thumb.
5th harmonic
---<3.8>---<32?>---[0]---
6th harmonic
---<3.2>---<45?>---[0]---
7th harmonic
---<2.6>---<65?>---[0]---
First we need to practice getting the motion down, and locating the pivot points for open strings. The fret numbers inside <>'s are natural harmonics. Notice how each line has two natural harmonics, then an open-string artificial harmonic. All 3 pitches should be identical.
Harmonic: 3rd 4th 5th 6th 7th 3rd 4th 5th 6th 7th
Tab: --<7>-<5>-<3.8>-<3.2>-<2.6>----[0]--[0]--[0]--[0]--[0]-
pivot towards bridge ->
Notice how just as you move your left-hand closer and closer to the nut but in increasingly smaller distances for the natural harmonics, you also move your right hand closer and closer to the bridge in increasingly smaller distances for the artificial harmonics. Physically speaking, natural and artificial harmonics are the same thing - only the technique used to create them is different.
Let's get fancy:
4 5 6 5 4 4 4 5 6 5 4 4 4 4 e--[1]-[1]-[1]-[1]-[1]-[2]-[3]-[43]-[43]-[43]-[43]-[42]-[3]-[21]-
Now we are practicing holding the fret constant and changing the harmonic achieved, as well as changing the fret while keeping the harmonic order constant.
The basic effect of this technique is much different than when using the picking technique. The picking technique usually generates higher order harmonics that really stand out, useful to emphasize a particular note in a riff or solo. This technique is more often used to give arpeggiated chords a chime-like sound.
Tab with artificial harmonics via tapping usually look something like the above - the first number indicates the left-hand fret, while the number in ()'s indicates the fret number to tap to sound the harmonic. Remember, the tap isn't designed to actually fret the note in ()'s, but to simply tap the string into the top of that fret, causing the string to sound.
