It is very rare for a dance to be completed all on one level and jumping allows the performer to create flight and dynamic movement into the sequence.
Different types of jumping that you can add to a sequence
Jumping from the floor, jumping high, jumping long, landing from the jump, putting consecutive jumps together, jumping position in the air, assisted jumps, jumping with a partner or group, jumping with a prop, jumping on different body parts, jumping over something, jumping on to something, jumping off something.
Developing jumps in your sequence
Changing the type of take-off, holding different shapes through the air, changing the speed of jump, changing the direction of jump, timing of the jump to coordinate with music, partner or group, thinking about how you can link different jumps together.
