Root Movement by Fourths

When you are developing chord progressions, the principles of root movement reduce the choices from any given chord to three: root movement by fourths, thirds, and seconds. In the case of the first choice—root movement by fourths—the two chords will always have one note in common (see Figure 18.6).

Figure 18.6. Root movement by fourths.

This one note acts as a link between the two, with the other two notes offering contrast by change. Root movement by fourths is the strongest kind of root movement, and it is often used sequentially, such as in a cycle of fourths.
