Contrary to the uniform, homogenized, popular customs produced by the mass media, folk customs make people feel unique and special. They convey a sense of belonging to a group. The American square dance is different from other folk dances. It is the only one always directed by a caller who exercises the prerogative of extemporaneously choosing patterns from known basic movements. It's like knitting and crocheting, there's an infinite variety of patterns.
Nothing ever happens the same way twice.
Since square dance movements have no set pattern, new movements and calls are constantly evolving. This constantly changing face of square dancing keeps it ever contemporary and enjoyable. The choice of music adds even more variety. Add to this, the involvement in an aerobic exercise activity that is also a social event. Square dancing has been referred to as friendship set to music and it continues to exist as a folk art form faithfully practiced by families and friends for untold generations.
