What Do You Get From a CSz Philadelphia Improv Class?

In our classes, you will learn the basics of improvisation and apply it to scene work, characters, relationships and performance. These skills can be applied to any form of improvisation.

CSz Philadelphia specializes in Short Form Improvisation

What is Short Form Improvisation?

Short Form improvisation was first developed by theater director and acting coach, Viola Spolin in the 1950s as a tool to work with actors during rehearsals. These theater games were eventually transposed through her son, Paul Sills for The Compass Players (which eventually became The Second City) into performance games for the stage. The Compass Players, commonly believed to be America’s first improv troupe, would in addition to their signature “scenario plays,” play improv games like “Story” as part of their shows. 

While several acting traditions throughout world history have employed improvisation as a method of actor training, American Short-Form may well be the first time a group of actors have ever stood on a stage ready to act with no pre-planned ideas of what their resulting scenes would depict.

Short Form takes the principles of improv and applies it to  games and scenes. Some games are scene-based, some are character-based, some are gimmick-based, but all use the improv skills that we teach you in each level of our classes: commitment, heightening and decision making. 

Short Form improvisation is used in popular and successful shows like Who’s Line Is It Anyway? and ComedySportz. It is also particularly effective in the game of life.
