Watch the "Soul Ache" Tap Harmonics online guitar lesson by Dmitry Lisenko from Percussive Acoustic Bass (Foundry)
We already know how to play this one, so now let's look how to play harmonics there. After the tap slide, our interval sounds, and we have tap harmonics on the 19th fret on the G string and the 17th fret on the D. Then, we do exactly the same over the next chord. Here we're playing harmonic not at the 12th fret, but at the 5th fret. It's the artificial harmonic, but not the octave. You can also play artificial harmonics after 5th, 7th, 9th, or 12h fret.
