in the 5 chord, you are adding an extra Bb, which is 6th of the tonic but a 2nd (or is it 9th) of the 5 chord. is that right?
I'm guessing you talking about this chord, Ab / Cb-Eb-Gb-Bb. This chord is an Abm9 chord. So, basically I am just changing the natural 5 chord in Db, Ab-C-Eb, into an Abm9 chord, Ab-Cb-Eb-Gb-Bb. I am playing the root in the bass, and everything else in my RH.
in the 1 chord, you are adding an Ab, which is a 5th of the tonic. is that there for color, or because it resolves well to the next chord? (you'll probably say both)
You talking about this chord, Db / Cb-Eb-F-Ab. This chord is a Db9 chord. So, basically I am just changing the natural 1 chord in Db, Db-F-Ab, into an Db9 chord, Db-F-Ab-Cb-Eb. I am playing the root in the bass, and everything else in my RH. Of course, the notes are switched up a little, but that's o.k.
In the 4 chord, you add Ab (5th of the tonic). i guess that means yuu are adding adding another 9th.
You talking about this chord, Gb / Bb-Db-F-Ab. This chord is a GbM7/9 chord (I think that's how it would be written). So, basically I am just changing the natural 4 chord in Db, Gb-Bb-Db, into a major 7th chord and adding the 9th. I am playing the root in the bass, and everything else in my RH.
So, I guess your explanations are correct, although I would be careful and not try to analyze too much. Try to simplify theory as much as possible, trust me.
If I understand correctly, you are adding alot of nice 9ths here.
Yes, I am adding 9ths, but I am also using m7 and M7 chords as well. Using the wrong kind of 7th can throw the whole chord off.
