Combinations of Motion
The two chapters "Simple Prolongation" and "More Prolongations" have presented numerous examples of
neighbouring and passing motions used together to produce chords. A great many combinations have been
shown, and the reader may well be wondering if all combinations are possible, or if some are better than
others. Many combinations are possible, but it is clear that composers preferred some, and strictly avoided
others.
We have already seen that motion in parallel thirds is commonly used and works well. We have seen all
possible combinations of neighbours in thirds, as well as the passing 123+345 motion in which the top and
bottom lines are moving in thirds.
The inversion of the third - the sixth - works just as well.
Motions which use the strong resolving notes of the dominant seventh chord work very well and are very
common. These motions, you will recall, are - combined with - .
