As was mentioned earlier, the Khon drama, commonly called
the "masked-play," involves singing, dancing, acting, acrobatics,
and music. The singing is accomplished by an offstage chorus
which also recites the narrative and dialogues. The majority
of actors are-unable to do this because of the masks they wear.
Some forms of the masked-play, probably older forms, did not
use singing. Most performances today, however, do use it.
