Interval formula: 1 3 5 9. A major triad with the 9th added and no 7th — a fresh, ringing chord: a decorated major, not a jazz one.

Chord tones

The triad holds the foundation while the 9th rings on top. With no 7th there's no jazz weight — the sound stays simple and open.

Sound character

Ringing and fresh — the classic open-string pop and rock sound.

Harmonic function

Tonic color. The same major, just dressed up; it doesn't change the function.
