What is acting?
Acting is showing a character to an audience so that they believe it. The actor is real, the situation is imagined, but the feelings and actions must look true.
Actors work in theatre, film, radio and street performance. In all of them the tools are the same: imagination, body, voice and the other actors.
Building a character
Given circumstances
These are the facts of the scene: who the character is, where and when the scene happens, and what has just happened. Read the script like a detective and list them.
Objective and obstacle
The objective is what the character wants in the scene ("I want her to forgive me"). The obstacle is what stands in the way. Playing a clear want gives the actor energy and direction.
Subtext
Subtext is the meaning under the words. "Nice shoes" can be a real compliment or a joke. The actor decides which and shows it.
Many teachers use ideas from the Russian director Konstantin Stanislavski, such as "the magic if": What would I do if I were in this situation?
Body: posture, gesture, levels and status
Posture is how you hold your body. Gesture is a movement that shows meaning (a pointed finger, an open palm). Facial expression shows feeling.
Levels mean height on stage: standing, sitting, kneeling, lying. A character on a higher level often looks more powerful.
Status is how much power a character seems to have. High status: still, upright, steady eye contact. Low status: fidgeting, looking down, taking up little space. Status can change during a scene, which is very interesting to watch.
Proxemics is the distance between characters. Close can mean love or threat; far can mean fear or coldness.
Voice: volume, pace, pitch, pause
- Volume (projection): loud enough for the last row, without shouting. Breathe from the belly.
- Pace: fast can show panic or excitement; slow can show sadness or authority.
- Pitch and intonation: high or low, rising or falling. A rising pitch can turn a statement into a question.
- Emphasis: stress a different word and the meaning changes: "I didn't take it" vs "I didn't take it".
- Diction: clear sounds so every word is heard.
Action, reaction and timing
On stage, everything is a chain of action and reaction. One character does something; the other is changed by it and responds. Good acting is mostly good listening: react to what your partner actually does, not to what you planned.
Timing is when you say or do something. A pause lets a moment land and builds tension (the audience waits for what happens next). Comedy also depends on timing: the joke lands just after a short beat.
Actors combine many elements together: space, objects, rhythm, silence and contrast (fast/slow, loud/quiet).
Rehearsal, training and theatre with a purpose
Warm-ups prepare body and voice (stretching, breathing, tongue twisters). Improvisation means making a scene up on the spot, which trains quick listening. Hot-seating: an actor answers questions in character. Freeze-frames (tableaux) show a key moment as a still picture.
In rehearsal the actor tries choices, takes notes from the director and repeats until the scene is clear. Afterwards actors evaluate: what worked, what to change.
Theatre can explore a social issue such as bullying, waste or fairness. Forum theatre lets the audience stop a scene and suggest a better action; street theatre takes the play to where people are.
Try it: one line, five ways
Say the line "I'm going home now." five times: happy, angry, scared, bored, secretly sad. Change only your voice the first time, only your body the second time, then both. Record yourself on a phone and watch with the sound off: can you still tell the feeling? Then try the sliders in the last 3D step.
Key formulas and definitions
- Given circumstances: who, where, when, what just happened
- Objective: what my character wants; obstacle: what stops them
- Subtext: the meaning under the words
- Body tools: posture, gesture, facial expression, levels, proxemics, status
- Voice tools: volume, pace, pitch, pause, emphasis, diction
- Action → reaction: listen, then answer
- Pause = tension; timing decides when a moment lands
Worked examples
1. Script: a student comes late to class. Write the given circumstances and an objective.
Who: a Class 9 student. Where/when: classroom door, 9:15 a.m., during a test. What just happened: missed the bus. Objective: "I want the teacher to let me sit the test without a scolding." Obstacle: a strict teacher.
2. Show high and low status in the same scene: a shopkeeper and a customer.
High-status shopkeeper: stands still behind the counter, slow voice, steady eye contact. Low-status customer: shifts weight, looks at the floor, speaks fast and softly. Swap the status halfway to show the customer finding courage.
3. How can emphasis change the line "You ate my lunch"?
"YOU ate my lunch" = surprise at who did it. "You ATE my lunch" = shock that it was eaten, not just moved. "You ate MY lunch" = it was mine, not yours. Same words, three meanings.
4. Plan a short scene on a social issue: plastic waste.
Freeze-frame 1: a family throwing plastic in a river. Short scene: a fish (actor) reacts, coughing. Pause. Forum moment: the audience suggests what the family could do. Final freeze-frame: the river clean. Use levels (fish low, family high) and a long pause before the fish's line.
Common mistakes
- Waiting for your cue instead of listening. React to what your partner really does.
- Turning your back to the audience or speaking too softly. Keep an open body and project your voice.
- Showing a general feeling ("being sad") instead of playing a clear objective ("I want him to stay").
- Rushing every line. Without pauses the audience has no time to feel the moment.
