Major Ninth Chords
Let’s look at how to play an Emaj9 (“E major ninth”) chord on the piano. We’ll also learn the pattern for building any other major ninth chord.
What Are Major Ninth Chords?
Major ninth chords are major chords with two added notes. The added notes are the seventh and ninth notes of the matching major scale.
So to build a major ninth chord, we’ll start by building a major chord. Major chords are built using the first, third and fifth notes of the matching major scale.
Then we’ll add the seventh note of the matching major scale to the chord.
Since scales only have eight notes, we’ll need to repeat the scale into the next octave to find the ninth note. The ninth note is the same as the second note of the scale, but one octave up.
How to Play an Emaj9 Chord
Now let’s build an Emaj9 chord. First, we’ll build an E major chord by using the first, third and fifth notes of the E major scale: E – G♯ – B.
Then we’ll add the seventh note of the scale to our chord: D♯
Then we’ll add the ninth note of the scale, by repeating the scale into the next octave: F♯
So to play an Emaj9 chord, we’ll play:
E – G♯ – B – D♯ – F♯

We can use this pattern to build any other major ninth chord, by playing the first, third, fifth, seventh and ninth notes of the matching major scale!
Fingering
Since you probably can’t reach all these notes in this order with your right hand, you could play it a few other ways. One option would be to play an E octave with the left hand, and then play the G♯ – B – D♯ – F♯ with your right hand using fingers 1 – 2 – 3 – 5 (thumbs are 1’s).
Another option would be to move the F♯ down to the position of a second, and then play an E octave with the left hand, and use the right hand to play F♯ – G♯ – B – D♯ using fingers 1 – 2 – 3 – 5.
