Hi Bill,

You are quite right. The notes C, D, E, and G do form a Cadd9 chord. However, Bob was saying he did not play the E note when he played his C2 chord, therefore it cannot be a Cadd9 because the third (E) is missing. Cadd9 is a major chord and the third is required to make it so. Remove the third (E) from the set of notes and the chord then becomes a sus4 chord of some description and in this case it is a Gsus4 if I'm not mistaken. Let me hasten to add that I am not an expert when it comes to harmony and chord formation and I don't pretend to be. Perhaps someone else can shed a different light on this discussion and if so, I will learn in the process.

Thanks for your input, Bill. As the Tesco slogan says, "Every little bit helps!"

Take care,

Chuck
