Other common features of a dance studio include a barre, which can be either fixed to the wall or be a standalone move-able device that is approximately waist height and used as a means of support. As music is an integral part of dance, nearly all dance studios have a sound system for playing CD's or music via a Bluetooth enabled device; a remote control is essential for the sound system to make it easy for the instructor to repeat musical passages as needed.
