How to Practice Improv by Yourself: Solo Drills That Carry Into a Scene

Your improv class meets once a week. Or there is no class nearby, no team, and no friend who wants to play scenes in your living room. Meanwhile the audition notice says “improv skills a plus,” and you know the casting director might lean back after the scene and say, “Great, now just play with it.”

Improv looks like a group sport, and the best of it is. But most of what freezes people in a scene happens inside one head: the half-second where you judge an idea before you say it, the vague answer that gives your partner nothing, the moment you stop listening because you are planning your next line. All of that can be trained alone.

The short version: practice out loud, every day, for a short time. Drill saying the first thing without editing it, making specific choices, setting up who and where in one line, and showing a room with your hands. Then practice the part that needs a partner, listening and answering, against a recorded or read scene. Save the group work for class, and you will walk in with sharper tools.

What you are actually training when you improvise

Strip away the games and improv asks for a handful of skills: say something without censoring it, make it specific, accept what your partner gives you, and build on it. Only the last two truly need another person, though you can rehearse the habit of them alone. The first two are habits of your own mind, which is good news for anyone practicing alone.

There is a hint from brain research about why the censoring part matters. When Charles Limb and Allen Braun scanned six professional jazz pianists, they found that improvising, compared with playing memorized music, came with widespread deactivation in prefrontal regions the authors link to self-monitoring. Those were musicians, not actors, so treat it as a clue rather than a rule. But it matches advice improv teachers like Johnstone give: the inner editor gets in the way.

Keith Johnstone, author of Impro (1979), pushed his students the same way. He told them not to concentrate, not to think, and to do the obvious. Solo practice is a safe place to build that habit, because there is no one watching you say something dull.

Say the first thing, out loud

The core solo drill is simple and a little uncomfortable: speak before you judge. Thinking the answer does not count. The habit you want lives in your mouth, so every drill below is done out loud, ideally standing up.

• Word chains: say a word, then the first word it makes you think of, and keep going for one minute without pausing. If you stall, say the stall (“blank, blank, blanket”) and keep moving.
• Fast lists: set a 30-second timer and name ten things in a category, such as “things in a grandmother’s purse” or “reasons to call in sick.” Bad answers count. The point is the speed, not the quality.
• Object stories: pick up anything near you and tell a 30-second story about where it came from, starting the first sentence before you know how it ends.

You will notice a pattern quickly: your first answer is usually the obvious one, and the obvious one is usually fine. The obvious choice to you often looks fresh to someone else. Let it out, and save the clever choices for when they arrive on their own.

Make specific choices, every time

The second habit is specificity. A scene partner can do almost nothing with “I’m making food.” They can do a lot with “I’m burning the pancakes I promised your mother.” Specific details hand your partner something to react to, and they make you more interesting to watch.

Practice this as a rewrite drill. Say a vague line out loud, then say it again three times, more specific each time: “I went somewhere.” “I went to the lake.” “I went to the lake where we lost the canoe.” “I went back to the lake to find the canoe you swore you tied up.” Each pass adds a name, a place, a history, or a feeling.

Do the same with characters. Instead of “an old man,” try a retired school principal who still corrects everyone’s grammar. Specific characters are easier to sustain, because every new line has an obvious source: what would this exact person say?

Show the room with your hands

Improvisers call it space work or object work: using mime to handle objects in an imagined room so the audience can see it. Improwiki’s entry on space work makes two points that matter here: the room should be clear from what you do, without explaining it in dialogue, and every object, once established, has to be respected.

This is the easiest skill to drill alone, and the one many students skip. Do something real, like making tea, then step aside and repeat it with nothing in your hands. Feel the weight of the kettle, the size of the mug, the drawer you opened. Then do it again with an emotional choice attached: making tea while furious, or while trying not to wake someone.

Keep the room consistent. If you put the mug on the counter to your left, it is still there a minute later. In a real scene, walking through a table you set up is the kind of thing that makes an audience stop believing. Practicing alone, you can catch it every time.

Play both sides of a short scene

A good first line tells your partner who you are to each other, where you are, and what is going on. Teachers often call this the who, what, and where of a scene. Our guide to Viola Spolin’s theater games covers the group versions.

Alone, you can practice it with three-line scenes. Say a first line that sets up the relationship, the place, and the situation. Turn your head or take a step, and answer as the other person, accepting everything the first line established. Then give a third line that raises the stakes. Stop there and start a new one.

• Line one: “Dad, I told you the recital in the school gym started at six, and you brought the wrong kid.”
• Line two: “He was standing right where you said you’d be, and he called me Dad.”
• Line three: “That’s because he’s the neighbor’s kid, and they just pulled into the parking lot.”

Notice what the second line does: it never says “What do you mean?” or “No, I didn’t.” It accepts the wrong kid, adds a reason, and keeps the scene moving. That is the habit you want. Run ten of these in a row and the first line gets faster and clearer each time.

Practice listening with a partner who is not in the room

The skill solo drills cannot fully give you is reacting to a line you did not write. You know what your own second line will be before you say it. In a real scene, the other person surprises you, and the work is to hear it and respond, rather than wait for your turn.

You can get closer to that with a script. Take a short exchange, cover your character’s reply, and listen to the cue line. Then answer it out loud in your own words three different ways before you look at what the writer wrote. Here is a cue from Oscar Wilde’s The Importance of Being Earnest (1895), Act I:

JACK. ... That, my dear Algy, is the whole truth pure and simple.

Hear Jack’s line, then improvise three Algernon replies: one that agrees, one that mocks, one that turns it back on Jack. Every version that answers what Jack said, rather than ignoring it, is good listening practice.

Then compare Wilde’s. Algernon replies: “The truth is rarely pure and never simple ...” It takes Jack’s own words and turns them on him.

Offbook makes this drill easier because the other part is read aloud, so you hear the cue instead of reading it. Upload a scene, pick your role, and realistic voices read every other character. Set line detection to Manual, so it never moves on by itself, answer each cue in your own words, then press Enter or say “next line” to hear the next one. When you want to come back to the script, switch line detection to Lenient, then to Strict, so it holds you closer to the written words each pass. The video below shows how line detection works.

The free run lines tool reads classic scenes in Offbook’s voices and waits for your line, with no account needed. You can also pull a two-person scene from our plays library and use it for the cover-and-answer drill.

Borrow from the solo games that already exist

You don’t have to invent all of this. There is even a Spolin guide for working alone, compiled from Viola Spolin’s games, whose techniques have influenced modern theater. Northwestern University Press describes Theater Games for the Lone Actor as more than forty exercises that let actors side coach themselves at home, in rehearsal, or in performance.

Side coaching is Spolin’s term for the short prompts a teacher calls out during a game. Coaching yourself means giving yourself one plain prompt as you work, such as “see the cup” or “hear the other person.” It sounds odd at first, but it keeps your attention on the scene instead of on how you are doing, which is most of the battle.

Monologues help too. Pick a speech from our monologue library, learn the first few lines, and then keep going in the character’s voice for another minute after the written text ends. It trains the same muscle as improv, with a strong character to lean on.

A 20-minute solo session you can run tonight

Short and frequent beats long and rare. Here is one way to put the drills together:

• Two minutes of word chains, out loud, without stopping.
• Three minutes of fast lists, ten items per 30-second timer.
• Three minutes of space work: one real task, then the same task mimed, then mimed with an emotional choice.
• Five minutes of three-line scenes, starting each one with a who, what, and where.
• Five minutes of cover-and-answer listening with a short two-person scene.
• Two minutes of honest notes: what felt easy, and which drill you avoided.

Record yourself on your phone once a week. Watch for the pause before you speak, for vague nouns, and for objects that vanish. Those three are worth fixing first, and they all show up on video.

Why you still want other people, eventually

Solo practice sharpens your tools, but the payoff is the moment someone else hands you an idea you did not expect. That comfort with not knowing grows with practice. In a study by researchers at the University of Michigan and Northern Michigan University, 350 Detroit students in grades 8 to 12 took ten weekly improv sessions, and their discomfort with uncertainty and social anxiety both dropped by the end of the program.

That was group improv, so take it as a reason to join others when you can: a drop-in jam, a class, or a friend reading with you. Your solo work means you walk in already saying the first thing, making it specific, and listening. If improv shows up in an audition, our guide to handling improv in the room covers what casting is looking for.

Questions actors ask

Can you really practice improv alone?

Yes, most of it. Saying the first thing without editing, making specific choices, setting up a scene in one line, and space work are all habits you can build alone, out loud. The part that needs a partner is reacting to surprises, and you can get close to it by answering cue lines you have not memorized.

What are good solo improv exercises for beginners?

Start with word chains, 30-second fast lists, and mimed everyday tasks. Then add three-line scenes where you play both people. Keep each drill short and do them out loud; thinking the answers silently skips the part you are training.

How long should I practice improv by myself each day?

Fifteen to twenty minutes is plenty. Short daily sessions build the speak-first habit better than one long session a week, and they are easier to keep up.

Will solo improv practice help in auditions?

It helps with the moments when casting asks you to play with the scene. The listening drills matter most, because an improvised scene depends on hearing the other person and responding, not waiting for your next line.

Can I practice improv on my phone?

Most of these drills need no device at all. For listening practice with a scene, rehearse on your laptop with Offbook reading the other parts, and listen to your scenes on your phone anywhere to keep the cues in your ear.
