Which scale works over both Dm7 and G7?

D dorian and G mixolydian contain the same seven notes - they are both modes of C major. So one note pool covers the whole ii–V; only the target notes change.

Why does the ii–V sound like it is going somewhere?

Because the roots move down a fifth, which is the strongest root motion in tonal harmony, while the upper voices barely move. The bass creates the momentum, the guide tones create the continuity.

Dm7 → G7: the ii–V connection

Dm7 → G7 gets far less attention than the resolution that follows it, and that is a mistake. It is the smoothest chord change in the cadence: almost nothing moves, which makes it the place to build a line rather than break one.

Why this works

Dm7 is D–F–A–C. G7 is G–B–D–F. Two notes are shared outright: D and F. That is half of each chord held in common. Of the remaining voices, C falls a half step to B, and A falls a whole step to G. So the entire change is one half step and one whole step, with two notes standing still. This is why the ii chord exists: it delays the dominant while changing as little as possible, which builds expectation without creating new tension. The practical consequence for soloing is that you should *not* treat Dm7 and G7 as two separate problems. Play a line over Dm7 that already contains F - it is the 7th of G7, so it survives the change - and let C drop to B exactly when the chord moves. One note carries the whole ii–V.

How to practice this

Practise this as one bar of music, not two chords.

Step by step

Loop Dm7 – G7 at 80 BPM with four beats per chord, in frets 3–7.
Play D and F only, across both bars. They fit both chords - nothing needs to change.
Add C over Dm7 and let it fall to B exactly on the G7 downbeat. That single half step is the whole change.
Play a four-note phrase over Dm7 that ends on F, then continue it over G7 starting from F.
Now chain it forward: Dm7 – G7 – Cmaj7, and combine this half step with the F→E resolution from the next page.
