Depending on which definition of "cadence" you choose to accept, of which there are several, you may find that you have to determine the context in which to use it. For example, cadence, IS a movement of chords.

However, it is also a rhythmic line used to keep time, ie; the snare drum taps which keep soldiers marching in step. It can also be a song, sung by one in a group for timekeeping as well.
