Help naming a Chord Progression

[kurodo]

Hi all,

Below is a very basic chord progression I created but I am having problems labeling it up.
I'd like an accurate way that I could label it in roman numeral terms.

The strange thing is its not even a complicated progression but because it omits the occasional 3rd or 5th writing it out has become a real headache.



The progression uses only 6 chord voicings in total.

Here's my interpretation of what I think the chords are:

Chord Voicing 1: A Major
Chord Voicing 2: Em7 omitting the 5th but its Bass is a G or is it really a G6 omitting the 3rd?
Chord Voicing 3: Gsus2
Chord Voicing 4: D Major omitting the 5th
Chord Voicing 5: F# Minor omitting the minor 3rd or an F#5
Chord Voicing 6: B Minor

If you had to write it out as a numeral based progression to communicate to another musician what would you come up with?

I really could use help, I am open to any ideas and it doesn't matter how simple or complicated the resulting numeral based progression looks just so long as it could be played back exactly as shown above using the numeral system.

If you want to indicate it exactly, notate it. Roman number system doesn't even do that with conventional harmonies. Your chord names you believe are ambiguous are fine in themselves, it's up to you if that's a Gadd6 or Em7/G bass. It doesn't matter very much IMO.

It doesn't do any conclusion really so I don't know without hearing it. It kind of looks key of D but I'm not sure, in the abstract it isn't obvious to me.
IE: for instance the two F#s and two C#s is probably not something to convey conventionally, the voice-leading there, peculiar...

Thanks Jan,
I was hoping to avoid regular notation but under the circumstances it would appear to be the most sensible way.
True there's nothing conventional about the sequence, if anything its just a mixture of intervals with an a chord or two and probably shouldn't have ever been passed off as a progression.

You are right the melody that goes with it more or less stays in the key of D Major.

Cheers Jan

Looks like either the key of D Major of B Minor.

You need a musical key before you can go assigning roman numerals as the roman numerals indicate what number chord it is. (I won't get into modes)

Your chords are fine with the exception of the F# which needs a 3rd (or a 7th) in order to indicate if it's major or minor. Typically, if you're going to omit a note from a chord, the 5th is the best as it does nothing to indicate what the chord is.

For the key of D Major - A Major is V, (upper case roman numeral for a major chord) Em7 is ii7, (minor chords get lowercase roman numberals) etc.
If it's B minor - A Major is VII, Em7 is iv7, etc.
