Arabesque is a ballet position in which the leg is raised high in the air according to a certain formal shape.
In ballet, both legs are always externally rotated. Tango maintains this tradition for two reasons. It enables the base leg’s muscles to work more strongly. It creates a classic look with the free leg.
The toes are always pointed.
Front arabesque: Free leg’s hip is flexed, knee may be slightly flexed or extended. Torso is upright.
Side arabesque: Free leg’s hip is adducted, knee is extended. Torso is upright.
Back arabesque: Free leg’s hip is fully extended, knee may be slightly flexed or extended. torso is tipped slightly forward
In tango we usually don’t take our legs so high.
