One of the basic poses in ballet, arabesque takes its name from a form of Moorish ornament. In ballet it is a position of the body, in profile, supported on one leg, which can be straight or demi-plié, with the other leg extended behind and at right angles to it, and the arms held in various harmonious positions creating the longest possible line from the fingertips to the toes. The shoulders must be held square to the line of direction.
Attitude [a-tee-TEWD] It is a position on one leg with the other lifted in back, the knee bent at an angle of 90 degrees and well turned out so that the knee is higher than the foot. The supporting foot may be à terre, sur la pointe or sur la demi-pointe. The arm on the side of the raised leg is held over the head in a curved position while the other arm is extended to the side.

Battement [bat-MAHN] Beating. A beating action of the extended or bent leg. There are two types of battements, grands battements and petits battements. The petis battements are: Battements tendus, dégagés, frappés and tendus relevés: stretched, disengaged, struck and stretched-and- lifted .
Battement, grand [grahn bat-MAHN] Large battement. An exercise in which the working leg is raised from the hip into the air and brought down again, the accent being on the downward movement, both knees straight. This must be done with apparent ease, the rest of the body remaining quiet. The function of grands battements is to loosen the hip joints and turn out the legs from the hips. Grands battements can be taken devant, derrière and à la seconde.
Bras bas [brah bah] Arms low or down. This is the dancer's "attention." The arms form a circle with the palms facing each other and the back edge of the hands resting on the thighs. The arms should hang quite loosely but not allowing the elbows to touch the sides.
Cabriole [ka-bree-AWL] Caper. An allegro step in which the extended legs are beaten in the air. Cabrioles are divided into two categories: petite, which are executed at 45 degrees, and grande, which are executed at 90 degrees. The working leg is thrust into the air, the underneath leg follows and beats against the first leg, sending it higher. The landing is then made on the underneath leg. Cabriole may be done devant, derrière and à la seconde in any given position of the body such as croisé, effacé, écarté, etc.
Chaînés [sheh-NAY] Chains, links. This is an abbreviation of the term "tours chaînés déboulés": a series of rapid turns on the points or demi-pointes done in a straight line or in a circle.
Chassé [sha-SAY] Chased. A step in which one foot literally chases the other foot out of its position; done in a series.
Demi-pointes [duh-mee-PWENT] On the half-points. Indicates that the dancer is to stand high on the balls of the feet and under part of the toes. Also used in the singular, "sur la demi-pointe."
Derrière [deh-RYEHR] Behind, back. This term may refer to a movement, step or placing of a limb in back of the body. In reference to a particular step, the addition of derrière implies that the working foot is closed at the back.
Devant [duh-VAHN] In front. This term may refer to a step, movement or the placing of a limb in front of the body. In reference to a particular step the addition of the word "devant" implies that the working foot is closed in the front.
Échappé [ay-sha-PAY] Escaping or slipping movement. An échappé is a level opening of both feet from a closed to an open position. There are two kinds of échappés: échappé sauté, which is done with a spring from the fifth position and finishes in a demi-plié in the open position, and échappé sur les pointes, or demi-pointes, which is done with a relevé and has straight knees when in the open position. In each case échappés are done to the second or fourth position, both feet traveling an equal distance from the original center of gravity.
Fondu, fondue [fawn-DEW] Sinking down. A term used to describe a lowering of the body made by bending the knee of the supporting leg. Saint-Léon wrote, "Fondu is on one leg what a plié is on two." In some instances the term fondu is also used to describe the ending of a step when the working leg is placed on the ground with a soft and gradual movement.
Glissade [glee-SAD] Glide. A traveling step executed by gliding the working foot from the fifth position in the required direction, the other foot closing to it. Glissade is a terre à terre step and is used to link other steps. After a demi-plié in the fifth position the working foot glides along the floor to a strong point a few inches from the floor. The other foot then pushes away from the floor so that both knees are straight and both feet strongly pointed for a moment; then the weight is shifted to the working foot with a fondu. The other foot, which is pointed a few inches from the floor, slides into the fifth position in demi-plié. When a glissade is used as an auxiliary step for small or big jumps, it is done with a quick movement on the upbeat. Glissades are done with or without change of feet, and all begin and end with a demi-plié. There are six glissades: devant, derrière, dessous, dessus, en avant, en arrière, the difference between them depending on the starting and finishing positions as well as the direction. Glissade may also be done sur les pointes.
Grand, grande [grahn, grahnd] Big, large. As, for example; in grand battement. (To find terms starting with "grand," look up the second word of the term.)
Jeté, grand [grahn zhuh-TAV] Large jeté. In this step the legs are thrown to 90 degrees with a corresponding high jump. It is done forward to attitude croisée or effacée, and to all the arabesques. It may also be done backward with the leg raised either croisé or effacé devant. Grand jeté is always preceded by a preliminary movement such as a glissade, pas couru or coupe.
Pirouette [peer-WET] Whirl or spin. A complete turn of the body on one foot, on point or demi-pointe. Pirouettes are performed en dedans, turning inward toward the supporting leg, or en dehors, turning outward in the direction of the raised leg. Correct body placement is essential in all kinds of pirouettes. The body must be well centered over the supporting leg with the back held strongly and the hips and shoulders aligned. The force of momentum is furnished by the arms, which remain immobile during the turn. The head is the last to move as the body turns away from the spectator and the first to arrive as the body comes around to the spectator, with the eyes focused at a definite point which must be at eye level. This use of the eyes while turning is called "spotting." Pirouettes may be performed in any given position, such as sur le cou-de-pied, en attitude, en arabesque, à la seconde, etc.
Plié [plee-AY] Bent, bending. A bending of the knee or knees. This is an exercise to render the joints and muscles soft and pliable and the tendons flexible and elastic, and to develop a sense of balance. There are two principal pliés: grand plié or full bending of the knees (the knees should be bent until the thighs are horizontal) and demi-plié or half-bending of the knees. Pliés are done at the bar and in the centre in all five positions of the feet. The third position is usually omitted. When a grand plié is executed in either the first, third or fourth position croisé (feet in the fifth position but separated by the space of one foot) or the fifth position, the heels always rise off the ground and are lowered again as the knees straighten. The bending movement should be gradual and free from jerks, and the knees should be at least half-bent before the heels are allowed to rise. The body should rise at the same speed at which it descended, pressing the heels into the floor. In the grand plié in the second position or the fourth position ouverte (feet in the first position but separated by the space of one foot) the heels do not rise off the ground. All demi-pliés are done without lifting the heels from the ground. In all pliés the legs must be well turned out from the hips, the knees open and well over the toes, and the weight of the body evenly distributed on both feet, with the whole foot grasping the floor.

Relevé [ruhl-VAY] Raised. A raising of the body on the points or demi-pointes, point or demi-pointe. There are two ways to relevé. In the French School, relevé is done with a smooth, continuous rise while the Cecchetti method and the Russian School use a little spring. Relevé may be done in the first, second, fourth or fifth position, en attitude, en arabesque, devant, derrière, en tournant, passé en avant, passé en arrière and so on.
Ront de jambe [rawn duh zhahnb] Round of the leg, that is, a circular movement of the leg. Ronds de jambe are used as an exercise at the bar, in the centre and in the adage, and are done à terre or en l'air. When used as a step, ronds de jambe are done en l'air and may be sauté or relevé. All are done clockwise (en dehors) and counterclockwise (en dedans).
