What is a "barre"?

In ballet, a barre is a horizontal rail mounted on the wall used for support during warm-ups and exercises. Dancers hold onto the barre with one hand while performing various movements and stretches, which helps them maintain balance and proper alignment. The barre is essential for building strength, improving technique, and practicing fundamental steps. It is a key tool in ballet training, allowing dancers to develop their skills and prepare for more complex movements and choreography.
