It seems that you have recently touched the electric guitar!

I also played slipknot psychological society, which was very cool! But the fingering switching speed is very fast, so practice hard!

I don't know which part you are talking about, but it should be a prelude. Then the right-handed skills used in sequence are:

1. Palm-controlled sound (a must for metal guitars)

2.d-type plucking (the main technique of this song)

3. Artificial overtones (also called plucked overtones) This may be what you want to ask. It is called plucked chord overtone. There are a lot of teaching, words and videos on the Internet. This is a difficult skill. Generally speaking, when plucking the string and touching the three overtones on the string, the thumb side touches the string (the easy mistake is that the thumb is too hard, resulting in silence and no overtones). Please note that the dialed chord and thumb are played at the same time. !

This technique can't be mastered in a few minutes, it needs at least a few weeks of practice. If you find it too difficult or don't want to practice or understand the technical instructions, you can play the prelude of another guitar. After all, slipknot has two guitars, and you can't play it (but if you really want to learn the guitar part of No.4, you still need to practice artificial overtone, because slipknot has this skill in more than one piece! )

Another thing to note is that the guitar part of psycho-social music needs special tuning, and the tone of each string needs to be lowered! Many people don't notice this.

Pure hands, I hope it helps!
