The connection between dance and mathematics is undeniable, particularly in the world of choreography. Judith Rivas, a dance specialist, has highlighted several examples of this relationship, including the use of numerical terms to describe hand and foot positions in ballet. In all forms of dance, from ballet to breakdance, mathematics plays a role through the structure of music and the steps that dancers perform.
Rivas explained how different styles of dance are associated with specific musical rhythms and time signatures, which dictate the number of beats and steps taken by dancers. For example, social dances like merengue and polka are written in two-quarter time signature, resulting in two steps per measure. In folk dances like Mexican jarabe tapatío, steps are often named using numerical terms like “eight vices” or “seven sins.” Geometry plays a significant role in standard ballroom dances as well, where couples move in circular motions around the dance floor.
Rivas also discussed the use of symmetry and isometries in choreography. Choreographers like Rudolf Laban and Merce Cunningham have explored this relationship by developing notation systems based on geometric figures or using chance choreography to create unique sequences. Laban’s notation system for dance involved using geometric shapes to describe movements, while Cunningham used mathematical principles to generate choreographies that were both innovative and visually stunning.
Overall, the connection between dance and mathematics is evident in every aspect of choreography. By understanding this relationship, dancers can enhance their performances by incorporating mathematical principles into their movements. As Rivas put it, “Mathematics is not just a tool for measuring movement; it is an essential part of creating art.”
