Eadd2

Theory

The add 2 chord takes a standard major triad and adds the major second (2 semitones above the root) without removing the third. Eadd2 uses E, F#, Ab, B. This creates four-note harmony: root, second (F#), major third, and perfect fifth (Ab). The second and the third, sitting just one semitone apart, create mild dissonance — but because the chord has a clear major third, it retains its bright, stable quality. The add 2 differs from the add 9 in register (second vs. ninth) and from sus2 in keeping the third. It is most common in pop and indie writing where simple but colorful harmony is desired.

Musical Meaning

Major chords are the bright foundation of Western harmony — stable, resolved, and immediately recognizable. Their structure (root, major third, perfect fifth) creates a sound that feels complete and confident, like a musical declaration of "yes."

Voicing Tips

Add 2 keeps both the second and the third (unlike sus2 which replaces the third). This creates mild but pleasing dissonance between the second and third. Voice them a third apart rather than directly adjacent for the smoothest sound. The add2 can subtly brighten any major chord without significantly changing its harmonic function.

Practical Uses

• Adds texture to a plain major chord without changing its function
• I chord color in contemporary pop and indie guitar/piano writing
• Creates a brighter, more open sound than a plain major triad
• Works well under a melody that sits on the 2nd or 3rd scale degree
