8 ways to play an A sus 4 chord on guitar

After learning your open chords on the guitar, you’ll soon want to know how to play sus 4 chords, which often come up in many popular songs. In this post, we’ll be covering the A sus 4 chord, which is short for suspended 4. 

The A sus 4 chord has an easy open chord shape but there are many different ways you can play this chord throughout the guitar fretboard. By knowing different A sus 4 chord variations, you’ll be able to use them in different musical contexts. 

We’ll first cover some basic chord theory and then show you 8 ways to play an A sus 4 chord which you can start to incorporate into your playing.

Let’s get started.

A sus 4 chord theory intro

A suspended 4 chord means that the 4th degree replaces the 3rd of the chord. For example, a Major triad chord has the chord tones 1, 3, and 5 but a sus 4 chord has chord tones 1, 4, and 5.

This means that an A sus 4 chord has the chord tones A, D, and E.

Here is the formula for sus 4 chords below.

To compare, here are the notes for other chords with A as the root.

Now that you know what notes belong to the chord structure, let’s look at how to read the chord charts.

How to read the chord charts

The top horizontal line of the chord chart represents the high E string and the bottom horizontal line represents the low E string. The vertical lines separate each fret. The numbers in the blue dots tell you which fingers to use on the fretting hand.

The letters on the right of the charts tell you what notes you are playing on each string.

Most people first learn to play the previous A sus 4 chord, but another way you can play this is with the open 4th string like this:

A sus 4 barre chord on the 6th string

You can also play this as a barre chord starting on the 6th string. The following shape comes from the open E sus 4 chord. Notice that the notes on the top 3 strings are the same as the previous shape but we now cover all the strings using our 1st finger like this:

If the barre chord is too difficult to play, first try to get the notes from the 6th to the 3rd string. Gradually add the 2nd and 1st string as you develop more strength in your fingers.

Here is one more A sus 4 chord also using an open 5th string. This chord comes from the open D sus 4 shape. This shape is more suitable for a fingerpicking style of playing because some strings are avoided.

Wrapping up

It’s good to know different variations of playing a sus 4 chord because you have more flexibility to move around the fretboard and also when you need a specific note in the top to help define a melody that you are playing over.
