Ballet style and technique are rooted in five basic positions. They are:
First: heels touching, feet forming a straight line.
Second: heels wide apart, feet forming a straight line.
Third: one foot in front of the other with heel against the instep.
Fourth: feet apart, one in front of the other, heels in line.
Fifth: one foot in front of the other with the heel against the joint of the big toe.
Modern dance developed as a rebellion against the strict rules of classical ballet; however, modern dance did not totally abandon these positions. Instead, the positions were adapted to reflect the difference style of modern. Similarly, jazz dance also adapted these basic positions. Variations in the movements, use of arms, type of footwear worn, and tenor of movements distinguish each dance style.
