Why it sounds like that

A 7th suspended 4th is built from the formula 1, 4, 5, ♭7. The perfect 4th between A and D replaces the major 3rd, suspending the chord. Compare it to A suspended 4th, which omits the minor 7th G.

What goes wrong with A 7th suspended 4th?

  • The 2nd string buzzes because the index finger is not close enough to the fret.
  • The 1st string is muted by the pinky collapsing onto it.
  • The 4th string sounds dull because the middle finger is not pressing firmly.

When to use it

A 7th suspended 4th works as the V chord in D major progressions like D–G–A–D, the I–IV–V–I. It suits folk, rock, and blues feels where the suspended 4th delays resolution. Compare it to A minor to hear the difference in color.

Changing to and from A 7th suspended 4th

  • Sliding the shape down two frets to the 5th fret gives G 7th suspended 4th.
  • Sliding the shape down one fret to the 4th fret gives A♭ 7th suspended 4th.

Which voicing to use

The D inversion places the 4th in the bass, giving a grounded, open sound. The G inversion, with open strings, is easier and brighter. Choose the D inversion for a fuller voicing.

Common questions

How is A 7th suspended 4th written?

A 7th suspended 4th is written A7sus4 or A. The symbol A7sus4 is the most common.
