# How to fill the harmonic gap?

So I have thought of almost the entire progression for my trio that goes from D minor to D major. Here is what I have of it so far:

D minor -> C major -> B minor -> ??? -> A major -> D major

And here is the harmonic relation:

i VII vi ??? V I

And here are the respective key signatures:

1b 2#

The C major can be thought of as D dorian, at least at the beginning of the section that has that harmony because of the C -> D motion. But this goes from simply being D dorian to being full blown C major. The C major -> B minor motion is where the key change occurs from 1 flat to 2 sharps.

Thing is, I have no idea what harmony to use to bridge the gap between B minor and A major. On the one hand, I could simply not have this bridging harmony and go from vi to V directly. But on the other hand, I am wanting this bridging harmony because I want to reserve the dominant chord for after D minor appears for a third time. Overall this is my harmonic plan:

Dm ---> Bm -> Dm ---> ??? -> Dm ---> A -> Dm ---> D

As you can see, I have D minor occuring 4 times. The short arrows are to represent the sudden appearance of D minor which in my piece represent cold snaps. The long arrows are to represent the chord progression going towards D major which gets longer each time before D minor suddenly appears again.

So without using the tonic major early on or going directly from vi to V, how can I bridge the harmonic gap between vi and V?

• An obvious one from the circle of fifths is to bridge Bm and A with an E of some sort, preferrably E major, or E7. Or a tts of Bb(7). – Tim Mar 8 at 7:21
• What about gm, the sub dominant of dm, or even the major parallel of it G, as it has the commun tones of bm? I am very curious about your trio and hopefully we can see and listen to it when it’s finished. – Albrecht Hügli Mar 8 at 9:08
• How about an Em9 with the F# held over from the Bm? Or a Gmaj7 with the F# held over? Or move the bass via a Bb and use a dim7 chord over it. The choices are numerous. . – PeterJ Mar 8 at 12:02
• A9sus would be nice, but it doesn't really bridge any gap... G7 or Gmaj7? B♭9? – user45266 Mar 8 at 16:10
• You can think of Bm as the ii of Amajor that is the V of D major – Shevliaskovic Mar 28 at 18:48
