I explain it to my students like floors of a building: to build a dominant cord you can't have a ninth floor or an 11th floor or a 13th floor if there's no seventh floor. Otherwise, if you want those elements, you have to either spell them as a 2/4 suspension, a "6 chord", or just "add" them on to a triad (a small house). 🤷🏻‍♂️

Well articulated. It’s a complicated thing, and you made it really clear.

Why doesnt the C9 assume major and just have the expected major 7th. Flatting the 7th is the odd duck and should be written as C9min7? Seems like extra work. Newbie question.

And just for funsies if you do jazz a Δ or a capital M = a major 7th(or 9th, 11th, etc.) A lowercase m = minor seventh, a ° = diminished, and a Ø = a half-diminished (also known as a minor7b5). Fun!

Why is it not just Cmaj9 Cmin9 and C9? Why this add9? Makes no sense

Fred Stickley :
Dude ur leaving out an important fact. The real difference in these chords is their function. c9 is a 5 chord in major. Cmin7 is a 2 chord in major. All this depends on what chord happens before and after these chords. Referred to as Chord Families.

hmmm how would we signal a minor 9th interval in the chord then?

Why is there a naturalise marker on the Cmaj9? Isn’t the major 7th a B which would have been natural anyway in the a major scale?

Berklee le ha hecho mucho daño a la teoría musical con esa notación tan estúpida.

really useful to see it shown this way, they’re like building blocks. Makes it easier to practice this exercise in other keys—thanks!

Leaving out the 5th is theoretically incorrect. It’s also often used in practice in ninths.

It’s kind of funny how a C9 chord is just shorthand for C dominant 7 (add 9).
