Which of the following is NOT classified as an Artistic Element feature?

Artistic Element features in synchro skating are characteristics that enhance the performance's expression and creativity. They contribute to the overall artistry of the program, showcasing the skaters' style and interpretation of the music.

Flexibility is a physical attribute that, while it can certainly enhance a skater's ability to perform various moves, is not classified as an Artistic Element feature itself. It does not directly relate to the creative aspects of choreography, formation changes, or transitions that are integral to artistic expression in synchro skating.

In contrast, pivoting, weaving, and change of configuration are all recognized as Artistic Element features because they involve specific movements and formations that contribute to the visual appeal and complexity of the performance. These elements focus on how skaters interact with each other and their formations, emphasizing the synchronized aspect of the sport and the artistry involved in creating engaging routines.
