I am reusing a harmonic progression I wrote a few years ago, in a different context than the original. Here there is the new passage:
The first two bars are around Dm (dorian). There is a modal interchange in the Fm7 chord. The rest is standard. The other two bars are around Gm. The last four chords are preparing the following section in Am.
I doubt that the chord selection is right in this context. There are two points where I think the harmonic rhythm makes some chords to be not suitable here:
- The Dadd9 at the end of the 2nd bar
- The Gadd9 at the end of the 3rd bar
I think they can suit within another harmonic rhythm, but not in this context, as they are a kind of passing chords here. In particular:
- The Dadd9 seems here to be preparing the Gm section, so I think omitting the 7th is not correct.
- Same stuff with the Gadd9 chord. Not clear its function in this context; I think it should be replaced by any chord with dominant function, preparing the succeeding Gm.
Regarding the Eb9 chord in the middle of the 3rd bar, I think it could be ok, depending on the melody. It seems to be preparing the Dm(add9) chord, as a substitute of the dominant. The 9th could also be b9, but it is not a mistake, provided that the melody suits it.
What do you think? any other suggestions for improvement?
