Knowing the acting tools to use for each piece of drama is a skill that is developed with practice. Identifying the performance’s style, genre and form will often dictate how to perform a particular role, as each of these has conventions.
There are many ways an actor might change their approach depending on the performance’s genre, style or form. For example:
Performers might interact with the audience, eg through direct address or audience participation, but most of the time the performer to audience relationship is built more subtly, eg through eye contact and the use of space. The style of the performance will decide the methods of building the performer to audience relationship. It can be experimented with, eg by using downstage, close to the audience, for important or significant moments.
To engage an audience, performers need to be completely focused and remain in character throughout, known as a sustained performance. This can be tiring and can take a lot of practice throughout the rehearsal process.
Performers need to consider their own health and safety, as well as that of the audience. It is important to ensure that performers warm up both physically and vocally during rehearsals and before going on stage for any performance.
