Why it sounds like that

A suspended 2nd is built from the formula 1, 2, 5. The major second interval between A and B replaces the third, creating an open, unresolved sound. Compare this with A major, which uses C♯ instead of B.

What goes wrong with A suspended 2nd?

  • Letting the 6th string ring through adds an unwanted low E under the A bass.
  • Flattening the index finger so it touches the 5th string and deadens the open A.

When to use it

A suspended 2nd works as a passing chord in A major progressions like A–D–E–A, the I–IV–V–I. It also fits the I–V–vi–IV in A major: A–E–F♯ minor–D. Use it in folk, rock, and pop when you want a suspended color before resolving to A major.

Changing to and from A suspended 2nd

  • Move to A major by lifting the middle finger and fretting the 2nd string, 2nd fret with the index finger.
  • Slide the shape down two frets to the 10th fret to reach G suspended 2nd.

Which voicing to use

The open position is the easiest and most common. The 12th fret version is a barre shape with the same voicing an octave higher. The Asus2/B inversions put the second in the bass, creating a softer, less grounded sound.

Common questions

How do I write A suspended 2nd?

A suspended 2nd is written as A or Asus2.

What is the difference between A suspended 2nd and A add 9?

A suspended 2nd omits the third entirely, leaving only A, B, and E. A add 9 includes the major third C♯ along with the ninth B, so it sounds fuller and more resolved.

Can A suspended 2nd be used in place of A minor?

A suspended 2nd has no third, so it is neither major nor minor. It can substitute for A minor in some contexts, but it will sound more open and less dark.
