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 donβt play by relaxing your hand over them. Use power chords when you donβt wanna play barred chords, youβre trying to figure out a song by ear, or if youβre jamming hard! Power chords are like a super versatile cheat for guitar playing.
