Her Majesty’s theatre has a typical lyric theatre orchestra pit, accommodating 20 players comfortably, depending on the instrument mix. The rear wall is demountable, allowing considerable expansion. Alternatively, additional players may be accommodated by removing Rows A and B from the stalls. These extensions allow the pit to accommodate up to 90 players.  Both options must be discussed with the Technical Manager well in advance.
Please note the following:
When not in use, the pit can be in-filled at auditorium floor height
There are no additional seats to install when the pit is not required
There is no “orchestra pit lift
Treads connecting the auditorium floor with the stage can be made available by arrangement. Some loss of seats may result.
