You are standing in
the middle of the upper balcony in row "X". Above you is a good view of the
dome, which is a
parabolic reflector. It is 64 feet wide by 10 feet deep and is used to
reflect the sound from the stage to the audience.
Note how the theater is designed for sound, hence the rounded ceiling and
walls. The stage is like the small end of a
megaphone, broadcasting sound into the auditorium.
