G chord [Musical explanation]

The G major chord is a major triad with formula 1 – 3 – 5. Therefore, to build it we need G (1), B (3) and D (5):

what notes are in the G chord

This is due to the fact that a major chord is made up of 2 third intervals:

  • A major interval (4 half steps between the 3rd and root).
  • A minor inteval (3 half steps between the 5th and 3rd).

If we apply this principle to the G chord we obtain that:

  • B is the major third of G because it is 4 half steps above the root.
  • D is the perfect fifth of G because it is 3 half steps above the 3rd.

Thus, this confirms that the G major chord is defined by:

Root (G) – Major Third (B) – Perfect Fifth (D)

Let’s start by analyzing the 3 circles in blue, which indicate that on the strings 6 (E), 5 (A) and 1 (e) we have to place the fingers 2 (middle), 1 (index) and 3 (ring finger).

Note by the way the number 1 in black on the left that indicates on which fret we start playing the chord.

On the other hand, at the top we see that we have the characters:

G B D G B G

This simply means that in the:

  • Sixth string sounds the G note.
  • Fifth string sounds the B note.
  • Fourth string sounds the D note.
  • Third string sounds the G note.
  • Second string sounds the B note.
  • First string sounds the G note.

And at the bottom we find the numbers:

1  3 5  1  3 1

This indicates that in the:

  • Sixth string sounds the root (1).
  • Fifth string sounds the major third (3).
  • Fourth string sounds the perfect fifth (5).
  • Third string sounds the root (1).
  • Second string sounds the major third (3).
  • First string sounds the root (1).
