Asus4 guitar chords

A - D - E

Chord Theory

Asus4 chords consist of the 1st, 4th and 5 notes of the diatonic root scale of A Major. The 3rd is omitted giving the chord an openness and in most cases, a need for resolution - generally back to the A chord.

  • Chord: A suspended fourth - Asus4 (Asus)
  • Formula: 1 - 4 - 5
  • Notes: A - D - E

Asus4 (A sus) - A suspended fourth (1-4-5)

Spelling: 1st(A), 4th(D), 5th(E) - No third

  • In the 3rd position, the chord is written x079-10-10. We separate any fret greater than 9 with a hyphen so as not to create confusion with double-digits, otherwise the chord above would be written x0791010... too confusing.
  • sus4 chords are often used in all types of music. Whenever you play a major chord you always tend to add a sus4 and then back to the major chord, e.g., A - Asus4 - A, or D - Dsus4 - D etc. This tends to happen naturally when playing certain chords. The major chord to the sus4 creates a bit of tension, with a return to the major for resolution... works well.
  • sus4 chords can also be written as sus chords. We use sus4 as there is no confusion with sus2 chords.
  • Standard keys using Asus4 chords:  C Major, G Major, D Major, A Major, Am, Em, Bm and F#m. Each of the minor keys is the relative minor of the major keys, i.e., C/Am, G/Em, D/Bm, A/F#m. If you are playing songs in any of these keys, you may come across an Asus4 chord... generally played next to the A major or A7 chord.
