I did this one for a college assignment! Let me dig it out for you.
Producer – pulls everything together to produce the show, especially the money.
Theatre Owner – rents the theatre to the producer for the show. More often a company than a person.
Book – composes the final version of the story as told by the dialogue and lyrics. Writes dialogue.
Composer – writes music for the show, in conjunction with the lyricist.
Lyricist – writes lyrics for the songs and recitative.
Orchestrator/Arranger – takes the tunes from the composer and arranges them for the full band or orchestra, arranges incidental music.
Director - directs the cast, deciding inflection and interpretation of the script.
Choreographer – creates the dance
(Dialect Coach) – coaches the cast in any specific dialect or accent required by the piece
Costume design – designs the costumes, taking into account character, budget, body shape, set design and lighting design
Set design – designs the set, from the script. And with input from the director and possibly producer
Sound design – wires the theatre, decides on sound effects and surround sound/stereo.
LX design – designs the lighting. An artistic job, brought to life by technicians.
Wardrobe(construction and maintenance) – interpret the costume designs into constructed garments, then look after and repair them. Usually costume makers make the costumes and wardrobe look after them
Wigs(construction and maintenance) – makes the wigs from designs by the costume designer, style them, wash and maintain. Same with wigs – makers will make them and the wig department will maintain them.
Head Carpenter(construction and maintenance) – in charge of set construction and maintenance. Leads some of the stage crew.
Stage Crew – anything and everything that needs pulling on or off stage, they set.
LX Op – programmes the lighting desk according to the LX designer, then in production hits ‘go’ every time the DSM tells them to. In an emergency (say, desk crash) has to improvise with sub-masters.
Sound Op – a very complex and organised job, they bring up and down every sound channel(so that’s every microphone, every instrument in the orchestra/band, any sound effects and click tracks which need to be half silent to everyone except the conductor) at the correct time. They don’t have time for a script, they have to operate the show from memory. They also conduct mic checks(checking the mics work and aren’t making any unpleasant noises) before every show. And change the batteries.
Follow Spot Ops – point spotlights at people. They have their own cue sheets, and do not follow the DSM. They are responsible for knowing exactly what they are doing at any given moment because no-one’s going to tell them.
(Automaton Crew) – man any moving set pieces in the show, maintain them against hydraulic fluid leaks and generally keep everyone alive by not dropping them on their heads.
(Fly crew) – man the flies, hopefully counterweight and not hemp, flying people and sets in and out of the stage.
Stage Manager – makes sure everyone is where they are supposed to be at every point in the show.
DSM – calls every cue in the show. Every LX cue, every sound cue, every fly cue, every automaton cue, and often every principle performer to the stage. Do not disturb without very good reason. Doesn’t have to worry about follow-spots, though.
Rehearsal Pianist - plays the reduced piano score at rehearsals for the cast to sing and dance to, so they know the shape and counts of the music without having to pay the orchestra/band to play.
Musical Director – directs the orchestra/band in the music. Much like any director, they interpret the material to a particular effect.
(Resident Director) – in long-running shows, or those with multiple productions, a resident director is needed to keep the cast rehearsed and in line as the Director will often be attending elsewhere.
(Resident Choreographer) – as the resident director, but for the choreography.
Dance Captain – one of the cast, they lead the physical warm up and rehearse swings in their specific tracks.
(Animal handlers) – Look after and train any animals required by the show, eg. The snakes in Whistle Down the Wind.
(Children's Director) – directs any children in a show, as there will always be more children per role than adults, so they require much more time that the producer doesn’t also want to be paying the adult cast to be rehearsing for. Qualified to work with children.
(Children's Chaperones) – present whenever children are working, so rehearsing or on stage, to ensure that nothing untoward happens.
(Magic Consultant) – designs any magic tricks involved in the show, so that they are convincing and(especially if contortionists are involved) safe.
(Specialist skills coaches) – e.g. silk flying, plate-spinning, roller skating. Teach the cast specific skills as required by the show.
Marketing team – sell the show. Advertising and ticket offers.
