what's the difference between the two? i think i remember something like one or the other will contain a 7th along with the chord, but i can't remember for sure.

A 9th chord will include the 7th (1 3 5 7 9), whereas an add9 will just be the triad with and added 9th (1 3 5 9).

I think that's right

As a general rule, any time you see an extension beyond the 7th on a chord, a b7 is implied (unless specifically notated as "maj7") as well as the extensions that come before it (an 11 chord, for instance, will contain a b7 and a 9). When this is not the case, and instead you just want to add a specific extension onto a chord, you'll write it as an add# chord.

9: 1-3-5-b7-9
add9: 1-3-5-9
Someones knowledge of guitar companies spelling determines what amps you can own. Really smart people can own things like Framus because they sound like they might be spelled with a "y" but they aren't.

No, a 9 chord would be another way to write a dominant 7th, dont ask me why, but those 2 chords are identical in a chord finder

an add 9 chord is a Major with a 9, or 2 added to the chord

A 9 chord is a dominant chord in the sense that it has both a natural third and a flat seventh, but it is not a dominant 7th chord.

To un-confuse the thread starter....

A 9th chord includes the 7th, an add 9 chord doesn't....

DMaj9 - R 3 5 7 9
Dmaj add 9 - R 3 5 9

The same goes for the difference between sus and add chords...

Dsus 2 - R 2 5

Dadd 2 - R 2 3 5

You need to start using a different chord finder.
