The term 'BALLET beam' is a combination of two words, 'BALLET' and 'barre'. BALLET is a type of performance dance that originated in the Italian Renaissance courts of the 15th century. It is known for its grace and precision of movement. The barre is a stationary handrail used in BALLET classes to help dancers maintain their balance and alignment while performing various exercises. The barre is also used as a support for stretching and strengthening exercises.
