add9 anywhere or what?

Quick Q: Can you name a chord like CMaj7add9? I mean, it's a root, third, fifth, 7th and a 9th. And/or can/do you call it CMaj79? Thought of this chord when seeing the C69 chord (R,1,3,5,6,9). Just curious what the "correct" name is for this chord or if you can call it whatever you like (using the word 'whatever' lightly here).

Oh yeah, another Q. Seen that some write like C6/9 instead of C69. To me that would indicate that the 9 would be the bass a la the term Slash-chord. What are your thoughts and who's treating me to some grilled chicken with lots of booze tonight?

All replies and invitations are gladly appreciated.

I've been thinking more and more about this Maj7add9 thingie and, correct me if I'm wrong, but since we're stacking 3rds all the way up to the 9th wouldn't we end up with a Maj9 or am I wrong? I mean, if I've left out the 7th it would be a MajAdd9 wouldn't it? Just one added note.

This leads to another theory =) Let's say this would be a Maj9 and I wanted a 13th note. It would mean It's a CMaj9add13 then? I'm a very curious person =)

Sorry for stacking chord questions =)

Extended chords with the seventh are called major9, minor9, and 9 (for dominant)

Without the seventh they're called add9 and madd9.

If you add a 13 to an add9 chord it's just an add13. The 13 implies that both a 9 and 11 could be in the chord, but don't have to be. An 11 implies a 9.

Yeah...what he said :p

some of pop's best songs make use of nothing but add9 chords. good examples of this are message on a bottle by the police and satellite by dave matthews band.

the nine adds a sort of "open" sound to the chord. if you'd like to explore this kind of sound, i'd start listening to tori amos or kaki king.

as far as your own stuff, i wouldnt rely too heavily on the nine to give your tune the biting edge, but if you're looking to to add some flare or some personality, i suggest I-7add9 or IV-(add9). these two chords play vital cadential roles in contemporary music.

hope this helped, get back to me if you want some more tips straight from berklee.

I'd watch only the sus2 (Asus2 = A, E, B) has the airy open sound. The add9 (Amadd9 = A, C, B) is extremely tense sounding. Now when the seventh is involved, the 9th tends to have a different effect on the chord. A major 9th is less "lush" sounding than a major 7th. Adding a ninth to a dominant 7th chord levels out the balance of the chord. The dominant 7th being on of the strongest of the chords, the ninth softens it up a bit. So when a dominant 7th seems to strong, add the ninth. Now by adding a 9th to the minor 7th chord will kick the chord up a notch. Of all the chords, the dominant 9th is by far the most common.
