I went to an improv class. Improv is where you are on stage and you don’t decide what you are going to until you’re right on the stage. Improv can be funny and usually the improv I see is funny but I know that if you have an instrument you also can do improv and improv is a short way of saying improvisation. It just means you decide as you go along. Improv is a good way to learn to not be shy and to try new things really fast! My dad does the funny kind of improv and he likes it a lot.
