Start with the grey horse on the left who sings bass.   If you click on the "and of four" on each of the other horses, you can coordinate their quartet, or click each horse on and off at different parts of the measure to create your own version.  "When you click" determines on which beat of the measure each horse sings. There are 15 combinations: solos, duets, trios, and the quartet.
