11.40ii–V without immediate I

Jazz often gives you:

Dm7 → G7

and then goes somewhere unexpected.

So don't assume every ii–V must resolve immediately to its expected I.

Still, identifying the implied destination is extremely useful.

If you see:

Cm7 → F7

ask:

What key would this normally resolve to?

Answer:

B♭

because:

Cm7 → F7 → B♭maj7

is ii–V–I in B♭.
