Hi, this is my first post so I'm hope this isn't too stupid a question.

I know a little bit about chord formation, but I can't figure out what to call this chord. It has the notes B,D,A,C in it. I was thinking I could invert it to A,B,C,D. Is there such a chord with the 1,3 and 4 of the scale. Would this be a Amin (dd5?) add 9 or something along those lines. I hope my question at least made a little sense.

Thanks.

Well....

Any note can be the root, even if it isn't being played. So your notes are A-B-C-D.

If A is the root, you have 1-b3-9-11, or Am(add 9, add 11)
If B is the root, you have 1-b3-b7-11, or Bm7/11
If C is the root, you have 1-6-7-9, or Cmaj13
If D is the root, you have 1-5-6-b7, or D13 (possibly Dm13, but that would be really rare)

You could also be missing a root.... so there are other possibilities as well. Not all chromatic roots are possible - Bb can't be the root, since you have both a B and an A; same is true of Db. But you might have:

Eb as the root, (1)-#5-7-11-13, or Eb maj13+
E as the root, (1)-5-b7-11, or E11
F as the root, (1)-3-5-9-11. or Fadd9(add11)
F#/Gb as the root, (1)-b3-b5-b6-b11 - this wouldn't add up to a common chord
G as the root, (1)-3-5-9-11, or Gadd9(add11)
G# as the root, (1)-b3-b5-b9-b11 - also not common

It's all going to depend on context. Chords aren't named in isolation.

oh ok, thanks a bunch!

I forgot that you can omit the 5th of the scale if you have a 9 or 11th chord.

Thanks again.
