Do you know this guitar chord shape? An add9 chord is a triad chord with an added ninth note. For example, a Cadd9 chord consists of the notes C, E, G, and D (the ninth note above C).Functionally, the add9 chord often adds color and depth to a progression. It can be used in place of a major or minor chord to create a more lush or open sound. It’s commonly used in pop, rock, and folk music to add a sense of brightness and extension to the harmony. #guitarlesson #guitarchords #learningguitar #guit
