Open. Open for short, open. Literally speaking, openness means stretching all parts of the body completely. In ballet, it is a challenge for dancers to open the hip joint to both sides of the human body and drive the knee joint, wrist joint and toe to open completely. If the movement is deformed and uneven, it will cause muscle strain or ligament damage, which will damage health. The main function of outward opening is to stabilize the center of gravity of the body. Only when the state of the center of gravity is relatively stable can the dancer complete the dance movements of the upper limbs. "Opening" is a test of the ability of lower limbs. The correct opening action can stretch the dancer's body lines and show the graceful posture of the body lines. At the same time, the opening ability determines the performance ability of the dancer's lower limbs. The standard opening action can make the dancer's dance more spiritual and straight. Taking tendu's movements as an example, the basic body movements of outward opening perfectly explain the aesthetic concept of "the limbs extend radially outward" in ballet dance. ?

Nervous. Stretching refers to the stretching of feet, knees and ankles, and the strength should penetrate from ankles to toes. In fact, the stretching of the instep and toes determines the tension of the legs and knees. On the one hand, foot extension can visually extend the length of the legs and beautify the dancers' legs; On the other hand, foot extension can effectively train the sensitivity and control ability of ballet dancers' ankles, which is convenient for dancers to express their actions and feelings. The ballet dancer tightens the muscles of all parts of the body and concentrates on the vertical line in the middle of the body, thus making the body generate upward motivation. When you stretch your feet, you should stretch your toes upward so that they can completely grasp the toe. At the same time, your heel should be forced forward to ensure that your foot is not injured when you spin and jump. Stretching the foot is to mobilize muscles and bones, so that dancers can achieve the harmonious unity of body and spirit, and truly express the spiritual connotation of ballet dance. ?

Straight man. The ballet dancer's trajectory on the stage is linear, which requires the dancer to stand straight and show positive and noble spirit. The concept of straightness is mainly aimed at the verticality of the dancer's legs, knees and back, so as to achieve a vertical state of body stretching, so that the dancer's dance posture can be completely stretched and opened, which plays a visual modeling role in lengthening the body lines. Moreover, dancers keep straight and can always keep their center of gravity vertical. Only by ensuring the stability of the body can we complete the ever-changing dance movements. It can be seen that standing upright is not only related to the dancer's mental outlook and physical temperament, but also the fundamental guarantee for completing the dance movements.

Stand up. The concept of "standing" in ballet is a higher requirement based on the completion of "straight" movements, which is to upgrade ballet from the aesthetic feeling of physical movements to the artistic beauty and spiritual beauty of dance. Standing is to create a feeling of stretching on the basis of stretching the body. "Standing" is to keep the whole body upright and upright, and then accurately put the center of gravity of the body on the center of gravity of the legs, resulting in a noble sense of independence. Dancers can master the essence of standing posture, bring light and energetic visual feelings to the audience, achieve the harmonious unity of action and spirit, and show the elegant temperament of ballet. ?
