Wow. what a really cool conversation. Loaded with interesting facts about chords. Thank you both technicsplayer and Chuck. So technicsplayer, then the only diff between a C2 and Cadd9th, is in the Cadd9th, the 2nd note (or 9th) is played on top. Or rather, the highest note in the chord. Other than that they are the same.

I always seen them as the same. Generally when I play music, I'm playing from what I call a "lead sheet". Maybe it's a standard. Bascially on this will be the melody and the chords written out over the melody line. Once in a while there may be a few added phrases between during vocal rests. So when I play (in a band) using these "lead sheets", I have lots of freedom to improvise. I play any inversion I "feel" like playing of the listed chord. But often I use the melody line for my highest note (but not always). Anyway, I've just gotten into a habit of playing with the left hand C, G, C for the bass and C, D, G with the right hand for my C2. Leaving out the 3rd on my right hand. And now that you mention it, I think I've only seen the Cadd9 when the D note is the melodic note of that chord.

Thanks again you guys. This has been a very imformative thread. I must confess though I don't use one of those arrangers with auto chord play. I'm not even sure what the "Technics Discussion" board is for. I simply found this thread by checking "new postings as of today" a while back and seen the posting subject and was curious so I read it.

Wild.

Thanks again.
