Sorry to be pedantic, but a 9th chord actually has a 9th and a _flat_ 7th. For example C9 has the notes C-E-G-Bb-D. 9th chords are part of the dominant group, not the major group.
A chord with a 9th and a 7th is a _major_ 9th. For example, the chord C-E-G-B-D is Cmaj9 (sometimes written C triangle 9).
- jtauber 15y agoWell, I'm assuming by convention that the 7th is flattened, as the notation "C7" does.
- robocop 15y agoI think the convention for chord notation is different to the convention for scale degrees. The 7th note in C major is B, but a C7 has a Bb.
- _mayo 15y agoMajor 7 chords are explicitly written as such. So in the case of a C chord with a major 7, it would be noted as Cmaj7.
- robocop 15y agoTBH I think you should delete this post. I think I would have been confused had I read it when I was learning harmony theory. Please see http://www.idlewords.com/2005/04/dabblers_and_blowhards.htm http://www.idlewords.com/2005/04/dabblers_and_blowhards.htm.
