Hi.

To start this off, I'll say I believe I have a pretty solid understanding of scale notation and intervals (for things like 1,3,5,7 being a maj7 chord for example) as well as working within keys. I don't really do anything with accidentals at this point because I want to focus on what I can do within one key for now.

I have recently started learning the chord progression notation (stuff like I-V-IV for example) and I would like some clarification on how to do this correctly.

Here is my question:

I got this progresson in the key of C major. It goes:

C, Am7, G, F

I (not really knowing how) notated it like this:

I - vib7 - V - IV

I am pretty sure I got it right except for the 2nd chord, the Am7. As you can see, I labelled it relative to the Am7 itself and not according to the whole progression. So would I actually label the Am7 as vi5 to make it relative to the whole progression or am I way off? My understanding of things is that having the vi in lower case means a minor triad based off of the 6th degree.

Hope that was explained well!

EDIT: Got the G and F chord backwards.

That would be I-vi-IV-V

Sorry about that, I got the G and F reversed by accident on the first post so the last two would be V-IV.

How would you handle the added note in the Am7 chord though? (the G note) Wouldn't the notation specify the added note somehow?

Not necessarily a ii-V-! is a very comme jazz progression and those guys almost never play triads but we could maybe say I-vimin7-IV-V

Edit: Do keep in mind that usually we notate the 7 for dom7 as in V7 but I don't see it much for the other type of chords.

I-vi7-V-IV

As another poster said, unless the 7 is written maj7 or has a triangle symbol before the 7, it is assumed to be dominant anyway.

Cool, that clears that up. I guess it is more practical to notate the added notes relative to the chord itself than relative to the progression.

I'd notate as I-vi-V-IV, but for a different reason than the guy above... simply because the seventh is diatonic, so no need for any extra notation

I can understand that. Personally, I like things to be really specific so I would notate the seventh. From what I have learned in this thread notating the Am7 as vim7 is really redundant because the key makes it painfully obvious that it would be a dominant 7th anyway.

vi7 works for me, thanks guys!

Lol, I actually mistyped, I meant vi7... I just meant you don't need to notate the b7, because it's a diatonic note

I don't know if it's a typo but Am7 is not a dominant 7th chord. It's a minor 7th and in this context it does not have a dominant function.

EDIT
Do you understand the difference between a Am7 and A7 ?

Am7 = Aminor7 and the notes are A C E G
A7 = A dominant 7 and the notes are A C#E G

Again, I say this just in case as I'm still unsure if it wasn't a typo.

vi7 would be a minor seventh chord.

Yes I re-read and I saw this so I just deleted my message because it was not useful since I was the one misunderstanding.

Yeah, I saw that yesterday and I was all like

I still don't get it, but if I were to wager a guess I think he was implying that you don't actually realize the misunderstanding regarding the whole dominant 7th thing. To be honest, later on in this thread my understanding of what a dominant 7th is has been shaken a bit.

You see, I was mentioning the dominant 7th to refer to the b7 added to the Am. After that... well, I'm not really sure what was going on and I actually looked up some dominant 7th chords yesterday because of it. It's just the way I always looked at the b7 degree itself.

I think it has to do with the way I used the term to refer to a scale degree and the way you didn't seem to notice that even after the post you deleted. Really, that's my best guess.

I just hope they don't find this too hilarious; I wouldn't like to think that they are getting TOO much amusement at our expense.

I actually deleted my post because I realized that you were refering to the scale degree and I found my post useless. I usually refer to a b7 as a minor 7th interval but I know that you were not wrong. It's ok if I made a few regular laugh, I'm a funny person IRL and I don't mind
