Gesture
Gesture is an important part of the drama medium. It’s usually included with movement and mime. The most significant is usually hand gestures. Gloria Swanson who played the role of Norma Desmond in the classic Hollywood film, Sunset Boulevard, used over exaggerated and almost spider like gestures with her hands. This married well with the type of character she portrayed - a desperate ex-movie queen trying to hold on to youth and her young lover.
The wagging admonitory finger accompanying words like 'I have told you time and time again that this behaviour is unacceptable' is probably among the most familiar of all gestures. They tend to work as emphasis.
However, gestures can also amplify a question, such as pointing in a particular direction as you say 'Do you mean this way?' They can also convey a mood, such as a shrug of the shoulders to convey indifference.
A more subtle gesture would be arms out, almost as though you plan to hug someone, but you are using the gesture to embrace a crowd of people as you say, 'Welcome!'
