Martha Graham is known for introducing unique elements that defined her ballet style, emphasizing expressiveness and emotion over traditional technical precision. She pioneered the use of contract and release, a technique that embodies the physical expression of emotional states. Graham's choreography often depicted themes of human experience, focusing on personal and psychological narratives. Her innovative approach to movement and storytelling transformed ballet into a medium for exploring deeper psychological and sociocultural themes. By breaking away from classical conventions, Graham laid the groundwork for modern dance, influencing future generations of dancers and choreographers across various styles.
