These plays contain darker themes such as death and disaster. Often the protagonist of the play has a tragic flaw, a trait which leads to their downfall. Tragic plays convey all emotions, and have extremely dramatic conflicts. Tragedy was one of the two original play types of Ancient Greece. Some examples of tragedies include William Shakespeare's Hamlet, and also John Webster's play The Duchess of Malfi.
The term "play" can be either a general term, or more specifically refer to a non-musical play. Sometimes the term "straight play" is used in contrast to "musical", which refers to a play based on music, dance, and songs sung by the play's characters. For a short play, the term "playlet" is sometimes used.
