Deputy stage manager (DSM)
The Stage Management Association, says:
During rehearsals one member of the team must be present whenever the director is working with the cast. This is usually the DSM (deputy stage manager), whose duties naturally arise from knowledge of the director’s intentions.
Duties therefore include: preparing and keeping the prompt script (or ‘Book’) up to date, prompting, calling artists for rehearsals and costume fittings, passing on the director’s requirements to the SM (stage manger), designer, and all other creative and technical departments, liaising with lighting and sound designers before and during technical rehearsals.
The ability to read a score is essential in opera and ballet and often useful in musical theatre.
