Gadd9
G Add 9 · 4 fingerings
An add9 puts the ninth on top of a plain major triad without adding a seventh, so Gadd9 keeps the simplicity of a major chord while sounding brighter and more open. It's a favourite of acoustic songwriters, indie, and pop-rock precisely because it's so easy to voice on guitar using open strings.
