Chord Structure
The D Add 9 Chord is a four-note chord, composed of the notes D, F#, A, and E. This chord is built upon the D Major scale, which consists of these notes in the order of root, major third, perfect fifth, and major seventh (1, 3, 5, 9). When building the D Add 9 Chord, the seventh (b7) degree is omitted in favor of adding the 9th degree. This results in a more satisfying and melodious sound compared to the parent major chord (1, 3, 5, b7).
Interval Spectrum
The D Add 9 Chord, like all four-note chords, has a specific interval spectrum that contributes to its unique character. The chord shares several key intervals with the D Major scale:
- Root (1)
- Major Third (3)
- Perfect Fifth (5)
- Major Ninth (9)
These intervals create a well-balanced and pleasing tone that is characteristic of the D Add 9 Chord.
Scale and Name Variations
Given its structure and the fact that it is built upon the D Major scale, it's no surprise that the D Add 9 Chord has several variations in scale degree names. While the scales are the same, the Chord Name and Interval Name Variations reflect the changes in the degree structure. For example, the Chord Name for the D Major Scale is simply Major, while the D Add 9 Chord is known as Dadd9 or D9. Similarly, the Interval Name Variation for the D Major Third is Major Third, and the D Add 9 Chord uses the term Major Ninth instead of the more general term Augmented Ninth.

- Play the 3rd string, 5th fret
Fingering Instructions
Playing the D Add 9 Chord on the guitar can be quite simple once you get the hang of it. The diagram below illustrates three common ways to play the chord:
-
Open Position: This method plays most of the chord open, with only the 6th string (G) left open. This approach creates a rich, full sound that is characteristic of many modern rock and indie songs.
-
Barre: A three-fret barre technique can be used to play the chord efficiently, although it takes some practice to nail it. When barreing, use the 6th string (G) to finger the 1st string (D) to 4th string (G), the 2nd string (A) to 5th string (B) to A (the E), and the 3rd string (D) as played.
-
Fork: This variation splits the chord into two parts, played with fingers or palms from the lower and upper strings, respectively. While this method is less efficient than the others, it can be played more slowly and with fewer notes, making it easier for beginners.
How to Use in Songwriting
The versatility of the D Add 9 Chord makes it a staple in many songwriting frameworks. It can serve as a base note for other chords, a pivot point for modulating, or a standalone feature in solos. The chord is often used in combination with other standard guitar chords, such as the G major and C major chords, to create interesting harmonic patterns.
