As a guitarist this is a very popular jazz chord and it is played as a dominate chord, R, 3, b7, 9. Like Mario said, for us guitar players we generally use only 3 note chords except when its Jazz and we use 4 note chords like C9 . grin




Here is what this old man was taught many years ago, from the lowest to the highest note:
Cadd9 = C-E-G-D
C2 = C-D-E-G
Csus2 = C-D-G

The confusion comes in when the Cadd9 and the C2 chords are in different inversions, then you might not be able to tell which is which.

YMMV

I get most of my exercise these days from shaking my head in disbelief.
