We generally know that the three-step dance should use music with a three-quarter beat, and the four-step dance should use music with a two-quarter or four-quarter beat.
The ten-step, twelve-step, sixteen-step, etc. in square dance are different from what we usually call three-step and four-step dance.
The steps in square dance refer to a group of movements consisting of several steps, and this group of movements can be danced repeatedly in a song. For example, the sixteen-step "Meeting You is My Destiny" is a set of sixteen steps that are danced repeatedly in the song "Meeting You is My Destiny" until the end of the song.
The same piece of music can be danced in ten steps, twelve steps, sixteen steps, twenty-four steps, thirty-two steps, forty-eight steps, sixty-four steps, etc.
