Gadd9 Chord

The Gadd9 chord is a added ninth chord built on the root note G. Its notes are G, B, D and A.

Added ninth chords are open and shimmering. Unlike a ninth chord they leave the seventh out, so the added second degree colours the triad without any of the tension a dominant brings, a favourite of pop and worship guitarists.
