How to Learn Lines for a Devised Show (When the Script Is Still Being Written)

On the first day there was no script. There was a theme, a pile of interviews, a few prompts on the wall, and a director asking you to stand up and see what happens. Three weeks later you have a show. Parts of it came out of your mouth in an improvisation you barely remember, and now somebody has typed them up and handed them back to you.

That’s the strange thing about learning lines for a devised show. You’re memorizing words you helped make, in a text that’s still moving, often tied to movement you built before the words existed. The usual advice for learning a finished play doesn’t quite fit.

The short version: keep a record of what the group makes from the start, so you’re not learning from memory of an improvisation. Learn each section as a unit of words and movement. Treat the typed text as the new truth, even where you’d have said it differently. Then, once the text is set, drill it from the cues until you can say it without looking.

Why devised text is different to learn

Devised theater is work where the script, or the score for a mostly physical piece, comes out of collaborative and often improvised work by the ensemble rather than from a finished play. The same overview describes a common pattern: a long period of making lots of material, then selecting, editing, and refining it. A writer may work in the room or collect what the group makes and turn it into a script later.

So you meet the text three times. First as something you improvised. Then as a written version, cleaned up by a writer or director. Then as the final version after editing. Each step can change the words, and your memory holds all of them.

There’s good news in that too. Psychologists call it the generation effect: in Slamecka and Graf’s 1978 experiments, words people produced themselves were remembered better than the same words they simply read. Nobody tested that on devising actors, but it fits what many feel: lines you made yourself tend to come back easily. That suggests a catch: your own first version may come back easily too.

Keep a record from day one

The biggest risk in a devised room is learning from memory of an improvisation instead of from a text. An improv that felt brilliant on Tuesday is a blur by Friday. If nobody wrote it down, three actors will remember three different versions.

Good companies plan for this. Writing about devising I LOVE YOU G, the director of Massive Company describes meeting the stage manager before rehearsals to agree how she would record the script as it took shape. If your company hasn’t sorted that out, ask who is keeping the text, and how you’ll get the latest version.

• Ask the director or stage manager who holds the master copy of the script.
• Ask whether new versions will be dated or numbered, and keep only the latest one in your bag.
• Write the date at the top of every page you get, so you can tell versions apart at a glance.
• Record a quick voice memo after any improvisation the director wants to keep, with the company’s agreement.
• Note which sections are still open and which the director has called finished.

Don’t memorize anything the director hasn’t kept. The same Massive Company account says writing made in response to prompts was rarely used as first written; it was worked on the floor and often changed a lot. Learning a first draft hard is how you end up fighting it later.

Learn words and movement together

A lot of devised work starts with the body. Tectonic Theater Project’s devising method, Moment Work, puts every element of the stage on an equal footing with the words: a Moment can be built from gesture, a prop, or text, and Moments are then put in order to make a play. Frantic Assembly describes its own approach as a series of tasks, each broken down into building blocks.

That’s useful for memory. Research by Helga and Tony Noice, summarized by the Association for Psychological Science, found that lines learned while making a fitting movement were remembered better later than lines learned without one. In a devised show, the movement often came first, so let it carry the words.

Learn each section as a unit. Walk it while you say it. If a line belongs to the moment you cross to the chair, practice it on the cross, not sitting on the floor with the script. For long physical sequences, our guide to memorizing blocking has more ways to fix the moves.

Let the written version win over the improvised one

Here’s the trap. You said something in an improvisation, the writer tightened it, and now the script says it differently. In the run, your mouth goes back to your own words. They feel more natural, because they were yours first.

Treat the written version as the new truth. It was changed for a reason: to set up a cue, cut a repeat, or make a joke land. When your old version comes out, stop and say the written one again a few times, right away. Then say the cue line before it and your new line after it, so the new version gets attached to the moment.

This matters for the people around you. A paraphrase can drop the word your partner was waiting for. One stage manager, writing on a University of Lincoln student blog, notes that even a small script change can alter the order of lighting and sound cues. Your words may now be someone else’s cue too.

If you do want a line back, ask the director. Don’t fix it on your own in a run. Our guide to stopping paraphrasing has more on getting word-perfect when your memory keeps rounding off.

Verbatim text needs exact words

Some devised shows are built from real people’s words. Tectonic’s The Laramie Project came from interviews: the author’s note reproduced in a 2025 program says company members traveled to Laramie six times to interview people in the town before transcribing and shaping the material. In the finished play, eight actors play more than sixty characters.

In verbatim work, close enough isn’t. The Observer notes that the playwright Alecky Blythe feeds edited interview audio to actors through earphones during the performance, so they keep the speakers’ hesitations and half-sentences. The same article says London Road was the first of her pieces where the actors learned the lines instead. In that show, the spoken text is reproduced exactly as recorded.

If you’re learning verbatim text, learn the “ums,” repeats, and broken sentences as written. They’re the character. Listen to the source recording if the company has one and is allowed to share it, and say the text along with it until the rhythm sits in your mouth.

When you play many people

When you play several people, learn each one’s text as a separate block, with the cue that brings them on. Give each a physical anchor: a posture, a prop, a way of sitting. The switch in your body helps the switch in your words.

Once the text is set, drill it like any play

At some point the group stops making and starts fixing. In new-play development, this is sometimes called locking the script. In a rehearsal diary for the new play My Master Builder, the team planned to lock the script at the end of week one, with no more cuts or edits until previews. Devised shows can fix much later: the Massive Company director spent much of the final rehearsal week editing.

Ask the director when the text will be fixed, and plan around that date. Until then, learn the shape of each section and the cues, and go word-perfect on each section as the director calls it finished. Once the whole text is fixed, go word-perfect on everything. Our guide to handling script changes in a new play covers what to do when a set section still gets a late rewrite.

If you rehearse with Offbook, realistic voices read every other part and wait for your line. You can hide your lines while everyone else’s stay visible and say each one from the cue, and when one line changes, you can edit it in the scene instead of starting again. You can also turn any page into first-letter cues with our free line memorizer.

A plan for the weeks of a devised process

1. Week one: agree who keeps the text and how versions are dated. Learn nothing word for word yet.
2. Each day: read the latest pages that night, and cross out what was cut so it doesn’t come back.
3. As sections settle: learn each one as a unit of words and movement, on your feet.
4. Where your improvised words were rewritten: say the new version a few times, then run it from the cue.
5. For verbatim text: learn hesitations and repeats exactly as written.
6. From the date the text is fixed: drill every section from the cues until you don’t need the page.
7. In tech: note which of your lines are now light or sound cues; those are the ones a paraphrase will break.

Questions actors ask

How do you learn lines when the script keeps changing?

Learn the shape and the cues first, and save word-perfect learning for sections the director has called finished. Keep only the latest dated version, and drill any changed line from its cue the same day.

When should a devised script be locked?

There’s no fixed rule. It depends on the company and how long the process is. Ask the director for a date, because knowing when the text stops changing is what lets you plan your memorizing.

Is it easier to learn lines you wrote yourself?

It can be. In memory experiments, material people produce themselves tends to be remembered better than material they read, though this hasn’t been tested on actors. Your first version can stick too, so be strict about the written one when it differs.

Can I change my lines in a devised show?

Only through the director or writer. Once the text is set, other actors and the stage manager are relying on it for their cues. Ask in rehearsal rather than changing it in a run.
