Building Major Chords: Triads
The formula to building the Basic Major chord is: Use the 1 3 5 notes out of the scale. The scale being the Major scale. You can build a Major chord in every key on the guitar.
A simple basic chord, say the C Major chord. When played in the first position closest to the headstock.
You are playing 3 notes. The 1 3 and the 5. Why? Because the formula to make a C chord is 1 3 5 notes out of the scale.
In this case the C Scale.
But look at the C chord in the chord diagram below. You will notice that there are more notes being used.
So how can this be, if you just said 1 3 5 notes? I’m glad you asked!
First off all the strings when played open. Meaning picking the strings, but not fretting the strings.
Makes a sound and the Pitch that the string makes is a note. The same note is the name of the string.

Of course this is when the strings are in tune. The strings are named from thickest to thinnest. E A D G B e.
Okay look at the C chord diagram. There is an (X) above the E string. Which means you are not going to play that string. When playing the C chord.
Your third finger is on the 5th string. The A string, at the third fret. Which when fretted there is a C note.
On the D string, 4th string. Is your 2nd finger, at the 2nd fret. And this is the E note.
Next is an open G string. When you play the C chord the G string is being played. Hence a G note.
That brings us to the B string. The second string, is being fretted at the first fret. And that is a C note also.
That leaves the open high e string. Which will make the pitch of the E note. When playing the C chord.
So you see some of the notes are doubled up in the chord. But they are still just the 1 3 5 of the scale.
The notes of the C chord are C E G C E.
