In this article you’ll learn how to construct the A flat major triad as well as how to play it on piano and guitar.
We’ve also included sections on inversions and figured bass for those that want a deeper understanding. Lastly, listen to some examples of popular songs that featured this triad.
Root , 3rd and 5th
The A flat major triad is formed of the 1st, flat 3rd and flat 5th of the A flat major scale.
- Ab – root note
- C – Major 3rd above the root
- Eb – perfect 5th above the root
Here is the triad written on the stave in the treble and bass clef.
Before you read on make sure that you have a basic understanding of intervals. Intervals are vital for understanding how triads are built. Check out our guide to major, minor and perfect intervals for more on this.
A flat Major Triad on Piano
Below you can see how to play this triad on the keyboard or piano. This pattern of notes could also be played starting on any A flat note.
However, the order of the notes must be the same:
- A flat – lowest note
- C – middle note
- Eb – highest note
This is called ‘root position’.
Ab Major Triad on Guitar
There are two simple positions that you can use to play a A flat major chord on guitar. Both positions can also be slide up or down the neck to play different major triads.
1st Inversion
A 1st inversion is where we take a triad but we start on the second note, which in this case is C natural. We still keep the Eb above, but then the Ab (or root) become the highest note.
This way of rearranging a triad gives us a different sound as the relative pitches of the three notes has changed.
- C – lowest note
- Eb – middle note
- Ab – highest note
1st inversion on Piano
On the piano we can play the 1st inversion of a Ab Major triad by starting on an C natural. They play the Eb above and the Ab above this.
1st Inversion of Guitar
Below are the most common shapes for playing a A flat major chord in the 1st inversion. Remember that we can only use certain shapes are the pitches of the three notes are important.
2nd Inversion
A 2nd inversion is where we take a triad but we start on the third note, which in this case is E flat. We still keep the A flat above this as we did from the 1st inversion. Then the C becomes the highest note in the chord.
- Eb – perfect 5th (lowest note)
- Ab – root note (middle note)
- C – major 3rd (highest note)
We could construct a 2nd inversion starting on any E flat note in any octave. The only thing that must stay the same is that the we use the A flat above and the C above that.
2nd inversion on Piano
On the piano we can play the 2nd inversion of a Ab Major triad by starting on a Eb. They play the Ab above and the C above this.
2nd Inversion of Guitar
Below are the most common shapes for playing a Ab major triad in the 2nd inversion. Remember that we can only use certain shapes are the pitches of the three notes are important.
