There are several careers connected with dancing: Dancer, dance teacher, dance sport coach, dance therapist and choreographer. Dancer Dance training differs depending on the dance form. There are university programs and schools associated with professional dance companies for specialised training in classical dance (e.g. Ballet) and modern dance. There are also smaller, privately owned dance studios where students may train in a variety of dance forms including competitive dance forms (e.g. Latin dance, ballroom dance, etc.) as well as ethnic/traditional dance forms. Professional dancers are usually employed on contract or for particular performances/productions. The professional life of a dancer is generally one of constantly changing work situations, strong competition pressure and low pay. Professional dancers often need to supplement their income, either in dance related roles (e.g., dance teaching, dance sport coaches, yoga) or Pilates instruction to achieve financial stability. In the U.S. many professional dancers are members of unions such as the American Guild of Musical Artists, the Screen Actors Guild and Actors' Equity Association. The unions help determine working conditions and minimum salaries for their members. Professional dancers at the Tropicana Club, Havana, Cuba, in 2008 Dance teachers Dance teacher and operators of dance schools rely on reputation and marketing. For dance forms without an association structure such as Salsa or Tango Argentino they may not have formal training. Most dance teachers are self-employed. Dancesport coaches Dancesport coaches are tournament dancers or former dancesports people, and may be recognised by a dance sport fe
eration. Choreographer Choreographers are generally university trained and are typically employed for particular projects or, more rarely may work on contract as the resident choreographer for a specific dance company. A choreographic work is protected intellectual property. Dancers may undertake their own choreography. A dance studio is a space in which dancers learn or rehearse. The term is typically used to describe a space that has either been built or equipped for the purpose. A dance studio normally consists of a smooth floor covering or, if used for tap dancing, by a hardwood floor. In most cases the floor is sprung, meaning the construction of the floor provides a degree of flexibility to absorb the impact of intensive dance exercise, such as jumping. This is considered vital to promote good health and safety.  Other common features of a dance studio include a barre, which is fixed to the wall at 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 cassett tapes, and a piano is still commonly used to accompany ballet and tap dance, especially in professional studios. In purpose-built dance studios, it is typical for at least one wall to be covered by floor to ceiling mirrors, which are used by dancers to see their body position and alignment. In China, the term dance studio is also used to describe a place which is established to teach dance. Commonly referred to as dance schools in Europe, they are often based locally and offer classes to interested students who live nearby. Depending on the studio, a variety of dance styles may be offered, or only one.
