Power chords are all Fives

Power chords contain only two different notes - the route note and its fifth - however you can play two route notes and two fifths.

A power chord must contain A (route note) and E ( fifth) -A5

D power chord must contain D (route note) and A (fifth) -D5

E power chord must contain E ( route note) and B(fifth) -E5

If you consider an E minor on the second fret - 5th and 4th strings, the three bass strings are, E open, B, and another E, these three strings played together form E5.

Others :G5 is G and D

C5 is C and G

'The fifth' - is the fifth note of the natural scale of the route note


E natural scale is E..F#..G#..A..B..C#..D#..E, if you play these notes it will sound: Do ray me far so la ti Do

If you count from left to right you can see that B is the fifth note
