Part I

IV to V

IV-V-examples

In IV->V, another common root movement, the bass moves by step, presenting the possibility of writing parallel fifths and octaves, a major part writing error.

To avoid the problem of parallel fifths and octaves, simply move the upper voices in contrary motion, that is opposite direction, to the bass.
