More on Common Tones

So let's continue on the common tones of the F (Sub Dominant) chord in the Key of C. The notes are F A and C. But now, lets drop the F note to an E note which makes it a 2nd inversion A minor (E A C), and instead of that, let's raise the C note 1/2 step to a C# note (E A C#). This 2nd inversion A chord ends up wanting to resolve to a D Minor chord very nicely. The D Minor chord is comprised of the notes D F and A. The E note would resolve nicely 1/2 step to the F note, the A note would remain a common tone and the C# note would have a tension that would resolve nicely 1/2 step up to the D note. So this 2nd inversion A chord (not A Minor, but A) resolves nicely to a 1st inversion D Minor.

Or try this: Take the root position C chord, C E and G and raise the C note 1/2 step to C#. This makes a chord comprised of the notes C# E and G. This is a 1st inversion A7 chord. This resolves very nicely to the D Minor chord. This can also resolve nicely to the D chord (D F# and A) because the 7 note which is a G will resolve nicely to the F#. So C# E G resolves to D F#.
