Hi, thanks for the reply, they are power chords now that I know of. It's also good to know other 1-finger and 2-finger chords to play rock, metal songs as three-fingers and four-fingers chords have their difficulty to master for me. Can you tell me more about 2 notes harmony chords too, this is the first time I heard of them?
Hi
cob2012,
2 notes harmony have special names assigned to them. Power chords is just one of the many.
Power chord is made up of root note and a fifth; sometimes including the eighth. The eighth note is simply an octave of the root note.
E.g.
1 + 5
1 + 5 + 8
E.g. Using C as the root note, C power chord is made up of
C G
C G C

For start, it is good for you to know that the thirds and the seventh are more commonly recognized by our human ears. The thirds determine whether a chord is major or minor, and the sevenths determine whether the chord is dominant or maj7 or not. IN other words, they influence the tone qualities, hence the term whether the notes are "in harmony" or not.
For instance, major chords will have tone qualities that makes me identify the feelings/descriptions of "bright", "open", "cheerful", "big". And minor chords will have one qualities that makes me identify the feelings/descriptions of "dark", "sad", "narrow", "emo", melancholic".
For example,
Major 3rd ---> Major chords
Minor 3rd ---> Minor chords
Major 7th ---> Maj7 chords
Minor 7th ---> Minor chords & dominant chords
That being said,
Perfect 5th is the two tone harmony commonly found in power chords, but you can also find them in most of any other chords. Because the 5th note doesn't really change much of the tone quality with the root note, it is named as "perfect". Fourth also has a similar quality, hence perfect fourth. It is made up of 1st and 5th notes of the major scale.
1 + 5
E.g. C G
Octave is made up of 1st and 8th of the major scale. It has a very "big" and "majestic" feel. For electric guitar, it can be used to make your lines cut through the accompaniment very well. Classical music also tend to use octaves very much.
1 + 8
E.g. C C

The best way to build your foundation in understanding theory is to first understand how a major scale is constructed.
E.g. In the key of C, a major C scale will use the major scale formula as such:
W W H W W W H
W = whole interval = 2 steps = 2 frets space
H = half interval = 1 steps = 1 fret space
Are you able to derive the notes for every key based on the major scale already?
