Here's how to play an E major triad on the bass guitar. We're gonna start with our note E as out root. We're gonna take out third and fifth notes from the E major scale. Those are G sharp, our third. And B, our fifth note from the E major scale. In order to play a two octave E major triad, we can start with our low E, play G sharp, the fourth fret. Play B on the second fret of the A string. Our next E will be at the seventh fret of the A string. G sharp is the sixth fret of the D string. B is the ninth fret of the D string. And then our other E is right next to it ninth fret of the G string. This is the two octave E major triad.
