Notes

  • 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 the A sus 4 chord: A Major, D Major, F#m, and Bm. Each of the minor keys is the relative minor of the major keys, i.e., A/F#m, D/Bm. 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.
