The A chord on the guitar



You can learn how to play the open position A chord and CAGED A shape!

In the video lesson above, I talk about the A chord and how it becomes an A shape. This is followed by discussing how we can extend the chord and even turn it into a Major Pentatonic, two different arpeggios, and all major modes.

Let’s start with just playing it as an open position chord because this is where the problems begin, especially when it comes to finger placement.

Theoretically, you should play this using all five strings. However, this is kind of impossible, especially as a chord shape. How do you actually fret this chord shape?

Open position A chord/shape

Don’t let the sadistic beginner teacher or your own ideals beat you down. The truth about the A chord is that you can’t really play it as it looks in a chord box, or in the Chordacus image you see here above.

It takes too long to fret the full shape, so let’s ignore the top string. Now all of a sudden, it’s super easy!

Here are all ways you actually can play an A chord.

  • Strings 3-5, this an A5 chord, there is no 3rd.
  • Strings 2-5, this is a full A chord, there is a 3rd on string 2.
  • Strings 2-4, this also a complete A chord, we have the 5th, root, and 3rd. This is what we’d call the 2nd inversion on a piano. On the guitar, we just call it an A shape.
  • Strings 1-3, this is also a complete chord as we have root, 3rd, and 5th. On a piano, we call this root position.

To learn how to actually play the A chord, not just fret it, you need songs that actually use it. Without this real-world experience, all this knowledge is just theoretical. After all, playing the guitar is a practical journey, not an academic one.

Among the beginner songs, we play the A chord in Robin Hood by Ocean Colour Scene. In Wonderwall by Oasis, we play it as an A7sus4.

The intermediate acoustic songs have the A chord in Babylon, Hey There Delilah, Mad World, and Whistle For The Choir.

Learn all these songs and you will have no problem playing the A chord in the open position, as well as a CAGED shape.


A chord extensions

Below are all possible extensions using an A-shaped chord. If you can see the intervals surrounding the A shape, you can play all these chords.

  • A major chord (root, 5th, root, 3rd, 5th)
  • Asus2 (root, 5, root, 2)
  • Aadd9 (root, 5, 9, 3)
  • Asus4 (root, 5, root, 4)
  • A7sus4 (root, 5, b7, 4)
  • A6 (root, 5, root, 3, 6)
  • Amaj7 (root, 5, 7, 3, 5)
  • A7 (root, 5, b7, 3, 5)
  • Amaj9 (root, 3, 7, 9)
  • A7#9 (root, 3, b7, #9)
  • A11 (root, 4, b7, 2)
  • A13 (root, 5, b7, 3, 6)

You need actual songs that have these chords in them in order to play and experience these sounds in context. Without this, you simply won’t learn them properly. Sign up for my guitar courses for this experience.


Building scales and arpeggios around the A chord/shape

Using the A-shaped chord as our framework, we can also build two arpeggios, a Major Pentatonic, the major scale (Ionian), Lydian, and Mixolydian.

Below are all intervals used to build these arpeggios and scales around the A-shaped chord.

If you can see all intervals around the chord shape, you can play all these arpeggios and scales.

Maj7 ArpeggioR357
Dom7 ArpeggioR35b7
Major PentatonicR2356
Major ScaleR234567
MixolydianR23456b7
LydianR23#4567
