Gmaj7 chord [Musical explanation]

The G major seventh chord is a tetrad with formula 1 – 3 – 5 – 7. Therefore, to build it we need G (1), B (3), D (5) and F (7):

what notes are in F maj7 chord

This is due to the fact that a major seventh chord is made up of 3 third intervals:

  • A major interval (4 half steps between the 3rd and root).
  • A minor interval (3 half steps between the 5th and 3rd).
  • A major interval (4 half steps between the 7th and 5th).

If we apply this principle to the Gmaj7 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.
  • F is the major seventh of G because it is 4 half steps above the 5th.

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

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

To sum up, in order to build the Gmaj7 chord we need to add the major seventh (7th) to the G major chord.
