Increase voice/actions so they will carry to the audience

Answer 1

Hi!

Increased voice/actions will only carry to the audience if your character and your acting is congruent to the play. If you are "showing" your actions, or speaking too loudly for the context of the play, people will call it "bad acting." And you don't want that.

Yes, when performing you need to project your voice, and you need to be congruent to the character and to the plays context.

Answer 2

When it comes to your voice, always make sure you are using your diaphragm to support instead of your lungs, along with speaking or singing from your chest instead of your head or throat. Speaking and singing from your chest gives your voice more volume and body than it would if you used your head voice, and using your throat can damage your vocal cords. In terms of actions, exaggerate them. There's a reason this is drama - you have to be dramatic with everything. If you're picking something up, make a show of it. The people in the back will be reading your movements to understand what you're doing, and so you have to make it visible to them too.
