Notes

  • In the 1st position, the chord is written x0203(0/3), with the chord notes x - A - E - G - D - E/G. The number and note after the forward slash (/), indicate the optional note. If you are not playing the optional note, disregard the forward slash and the number or note after it.
  • 7sus4 chords are used less often than sus4 chords in most types of mainstream music, with jazz and alternate styles using them to a greater degree. There is a little more tension created with a 7sus4 as opposed to a sus4 chord, but when used well, it can create an interesting backdrop or introduction for any melody line.
  • Other keys using the A7sus4 chord: D Major and Bm.
    Bm is the relative minor of D Major, i.e., both scales share the same notes and the same key signature. There are many other keys that could use this chord, but we concentrate on the 'standard' key progressions which means in this example, chords that utilize notes belonging to the D Major Scale ( D-E-F#-G-A-B-C#) also referred to as Scale Tone Chords... A7sus4 meets that condition (A-D-E-G).
