Amaj7 chord [Musical explanation]

The A major seventh chord is a tetrad with formula 1 – 3 – 5 – 7. Therefore, to build it we need A (1), C# (3), E (5) and G# (7):

what notes are in a amaj7 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 Amaj7 chord we obtain that:

  • C# is the major third of A because it is 4 half steps above the root.
  • E is the perfect fifth of A because it is 3 half steps above the 3rd.
  • G# is the major seventh of A because it is 4 half steps above the 5th.

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

Root (A) – Major Third (C#) – Perfect Fifth (E) – Major Seventh (G#)

To sum up, in order to build the Amaj7 chord we need to add the major seventh (7th) to the A major chord.
