In Musical Theatre, Opera, what percentage of ticket sales go to whom?

I've heard on average the composer gets 6% of ticket sales. But I don't know where to get real "industry standard" data on this?

Main Leads: __ %
Composer: __ %
Lyricist / Librettist:__ %
Supporting Leads:__ %
Lighting Person:__ %
Sound Person:__ %

Answer 1

Almost no one in musical theater or opera gets a percentage of the ticket sales. Musical theater is expected to make a profit and the risk is taken by supporters who put up the production money and own various percentages of the show. Everyone you name works for fixed fees or wages. If enough people buy tickets, the "angels" get money back, if not, then they lose their investment.
Opera pays people the same way (you don't get a star without a guarantee of payment), but since opera almost always costs more than ticket sales bring in, so donations and grants must be solicited to make up the difference.
For several of the positions you name, there is a further need to define the positions in more detail. For example, there are lighting designers, sound designers, composers, and libretists all of whom are usually paid a fee rather than a wage, salary, or percentage. On the other hand, there are sound operators, lighting operators, musicians and singers who are involved in every performance and are probably union members who are getting a guaranteed scale or higher and get paid or the show does not go on.
All this is complicated when a lead singer or other production person own part of the show or acts as producer to put it together.
