What structures/devices have you used in your duos?

we have used many different devices for our duet such as ; 

• cannon
• repetition on movements ( motif) 
• motif development 
• levels (using the floor)
• formations (changing places/patterns)
• dynamics ( force,speed,flow ) we have used force for the basketball motif and speed as bouncing the ball.
• contact
• symmetry
• climax ( lifts)
• movement components

we are also using the structure of our dance as ABC this is telling a story (narrative) 

Have you refined movement in your duos?
