Acting is an art and a skill, and it must be honed like any other skill. Good acting training will help you be one with your instrument (voice, body, movement, emotions) and teach you to rely on your impulses while you are living truthfully in your role.
At Actors In Action Conservatory, we teach the Liechty Technique, which takes a behavior-first approach to acting. We drill voice work, movement, moment-to-moment work (repetition), verb work, audition work, script analysis, and scene work over and over again, much like a pianist practices their scales or soccer players drill their foot work. This repetitive work takes the actor out of their head and into their instruments/impulses, so they can instinctively play a scene. The result is a fail-safe acting process that is always there for the actor no matter the circumstance or challenge.
