Director's notes on Proper Soliloquies.
An actor who aims to perform a soliloquy must look around their environment, focus on a significant element of the scene, and procced to describe with detail how the sight makes them feel - repeat the process with the rest of the scene -. The actor should change the tone of their voice between the lines depending on the current feeling of their character; shouting it all should not be neccesary and might be considered exaggerated.
