The D added ninth chord, often written as Dadd9, is a four-note chord that enriches the standard D major triad by adding a major ninth (E), resulting in the notes D, F♯, A, and E. This chord is constructed by stacking the intervals of a root (D), major third (F♯), perfect fifth (A), and major ninth (E). The inclusion of the ninth adds a bright, open sound to the chord, making it a popular choice in various musical genres, including pop, rock, and folk. On the guitar, the Dadd9 chord can be played in several voicings, with one common fingering being xx0230. The Dadd9 chord’s distinctive sound has earned it a reputation for adding a fresh, uplifting quality to chord progressions.
