Here is an example of power chords! Power chords can be played by playing two octave notes with a fifth in between. Make sure to mute the strings you donโt play by relaxing your hand over them. Use power chords when you donโt wanna play barred chords, youโre trying to figure out a song by ear, or if youโre jamming hard! Power chords are like a super versatile cheat for guitar playing.
