How to learn a whole play, not just one scene

Most advice on memorizing lines is really advice on memorizing a scene. That advice still works for a full play, but it isn't enough. A big role creates problems a single scene never does: the first act fades while you're learning the third, similar scenes blur together, and you can run out of time without noticing until tech.

A whole play is a logistics problem wearing a memory problem's costume. So start with the logistics.

Start by reading the play, twice

Read it once straight through for the story, ideally in one sitting, with your phone in another room. Read it a second time for your character's journey. Where do they start? What do they want in each scene? What do they know, and when do they find out?

Don't start memorizing yet. This reading gives you a map of the whole thing, and you'll hang every line on that map. If you know that your character has just heard terrible news when they enter in Act Two, you won't have to invent the tone, and the words will come more easily too.

Map your part

Next, make a simple table. List every scene you're in, with its page numbers and a rough count of your lines. Add three more columns: who else is in the scene, what your character wants in it, and how hard it looks.

This takes half an hour, and it may be the first good news you've had since casting: you're not in every scene. You'll also see where the big speeches are, and how much material you really have. You might also spot scenes that look alike, such as two arguments with the same character. Mark those, because they're the ones you're most likely to mix up later.

Work backward from your deadline

Find out when your director expects you to have lines down. That date is your real deadline, and opening night isn't. Count back from it and divide the part into weekly chunks.

Two rules make the schedule realistic:

• Don't divide evenly by page. A page of fast one-line exchanges and a page of monologue take very different amounts of time. Use your table to weight the hard scenes.
• Leave the last week empty. Everything takes longer than you expect. If you finish on time, you can use that week to run the whole play.

Say you have 30 scenes and five weeks until lines are due. Leave the last week empty and you're learning seven or eight scenes a week, so about one a day. That's doable. Start a week late and it's ten, so the single biggest thing you can do is start now.

Learn in story order, mostly

Learning in order helps, because each scene sets up the next and you build the same momentum your character has. But don't always start at the beginning of your learning session. The common result of that habit is a polished Act One and a shaky Act Three.

If your rehearsal schedule is working through the play out of order, it's fine to learn what's coming up next in rehearsal first. You'll get to use those lines right away, which helps them stick. Just keep your table up to date so nothing gets left behind.

Keep the old material alive

This is where whole-play learning differs most from learning one scene. Lines you knew perfectly three weeks ago will fade unless you come back to them, so every session needs two parts:

1. Review, about a third of your time. Test yourself on scenes you've already learned, starting with the oldest or weakest.
2. New material, the rest. Work on this week's scenes using the beat-by-beat method.

Spacing your review out like this is one of the most reliable findings in memory research. You don't need a complicated system. If a scene comes back cleanly, you can wait longer before reviewing it. If it comes back badly, look at it again tomorrow.

Build a thread through the play

Once you have a few scenes learned, start running them in sequence, without the scenes you aren't in. Say the last line of one of your scenes, then go straight to the first line of your next one. Ask yourself what happened to your character in between.

These transitions matter because they're where actors go blank in a full run. You come off stage, change a costume, come back on, and your mind is empty. If you've practiced getting from each scene to the next, you've got a route. It also helps to memorize a one-line summary of each scene, in order, so you can recite the plot of your own part from start to finish.

Sort out the lookalikes

Plays repeat themselves on purpose. A phrase comes back in Act Three with a different meaning, or two scenes open the same way. These are the classic traps, because a familiar line can send you down the wrong track and into the wrong scene.

Take each pair you marked on your table and compare them side by side. Find the exact point where they split, and work out why your character says something different this time. Then practice just that split, going back and forth between the two versions. Doing this once on purpose can save you a very awkward moment on stage.

Learn the other parts of the story

You don't need to memorize other people's lines, but you do need to know them when you hear them. Listen to the whole play regularly, including scenes you aren't in. Over a long rehearsal period, this gives you a strong sense of the rhythm of the play and what's coming next. It also helps if a castmate jumps a line, because you'll know where they've landed and how to get back.

Know when you actually know it

Feeling confident isn't a good measure. Use a more demanding test: you know a scene when you can say it with the script closed, at performance speed, starting from any point, while doing something else with your hands. Keep a simple record in your table of which scenes pass, and which lines keep tripping you up. For the final stretch, read our guide to getting word-perfect before tech week.
