The popular definition of tragedy is heavy drama in which everyone is killed in the last act, comedy being light drama in which everyone is married in the last act.
I'm a natural born show off. I love performing, and at school we had a really good music scene and an even better drama scene. When I got to university, I played in bands and did sketch stuff and it was always about coming up with material, which is why I never really practised and have no chops!! When I left uni, I carried on playing and trying out at stand-up.
A third variety of drama ... begins as tragedy with scraps of fun in it ... and ends in comedy without mirth in it, the place of mirth being taken by a more or less bitter and critical irony.
