What is the best book on improv?
Discovering the Ultimate Guide to Improvisation for Performers and Creators
(By Javier Guerra)
Why Improv Books Matter More Than Ever
Improvisation has transcended the traditional boundaries of theatre and comedy stages. Today, it’s used in classrooms, corporate boardrooms, and even in therapy sessions. With its growing popularity, the demand for quality resources has increased. And among all these resources, books remain one of the most accessible and effective ways to understand the fundamentals and intricacies of improv.
But with so many titles out there—some geared toward actors, others toward educators or public speakers—choosing the right one can feel overwhelming. Whether you’re a complete beginner or a seasoned performer, the right improv book can unlock new levels of spontaneity, collaboration, and confidence.
So, what is the best book on improv? Let’s take a deep dive and find out.
The Gold Standard: “Truth in Comedy” by Charna Halpern, Del Close, and Kim Johnson
Among the many books on improvisation, one consistently stands out as the essential read:
“Truth in Comedy: The Manual of Improvisation” by Charna Halpern, Del Close, and Kim Johnson.
This influential guide has shaped modern improvisation as we know it. Del Close, in particular, is considered the godfather of long-form improv and a mentor to some of the greatest comedy talents, including Tina Fey, Amy Poehler, and Bill Murray.
What makes this book special?
It introduces the groundbreaking concept of the Harold, a long-form improv structure still widely used today.
It emphasizes honesty and real emotion over contrived jokes.
It encourages actors to listen, collaborate, and build truthful scenes.
Quote from the book:
“The more you try to be funny, the less funny you are. The more honest you are, the more comedic you’ll be.” — Del Close
This perspective has revolutionized the way improvisers approach the stage—not as clowns trying to entertain, but as artists seeking connection and truth.
What’s Inside “Truth in Comedy”?
The book is structured around a series of key improv principles that build upon each other. Here’s what readers can expect:
The Basics of Agreement: “Yes, and…” is the cornerstone of all improv. The book stresses the importance of supporting your scene partner’s reality and building on it.
Group Mind: Successful improv isn’t about individual brilliance but collective synergy. “Truth in Comedy” dives deep into how to create that harmony.
Scenes with Substance: The authors teach how to build entire worlds and narratives without a script—creating real characters, real relationships, and real conflict.
The Harold: One of the most celebrated contributions of this book, the Harold is a format where multiple scenes and characters are introduced, explored, and brought together by the end of the performance.
Example Exercise from the Book:
A classic “Yes, and…” drill where two performers build a story sentence by sentence. One begins: “Let’s rob a bank!” The other responds, “Yes, and we’ll wear clown masks!” The goal is to embrace and expand, not block or deny.
Other Highly Recommended Books on Improv
While “Truth in Comedy” is widely regarded as the definitive text, several other books offer unique perspectives and valuable techniques. Here are a few more must-reads:
1. “Impro: Improvisation and the Theatre” by Keith Johnstone
A foundational text for improvisers and theatre educators, Johnstone’s book dives into status, spontaneity, and storytelling. His status exercises—where actors play with social dominance and submission—have become staples in acting classes worldwide.
2. “The Upright Citizens Brigade Comedy Improvisation Manual” by Matt Besser, Ian Roberts, and Matt Walsh
Created by the founders of UCB, this detailed manual covers everything from basic scene work to game-based improv. It’s perfect for performers seeking structure and clarity, especially in comedic improvisation.
3. “Improvisation at the Speed of Life: The TJ & Dave Book” by T.J. Jagodowski and David Pasquesi
For a more philosophical and artistic approach, this book is a masterclass in intuitive performance. TJ and Dave are known for their emotionally rich, unscripted performances that feel like scripted theatre.
4. “Improvise: Scene from the Inside Out” by Mick Napier
Napier brings a more rebellious voice to improv, encouraging actors to trust their instincts and break the so-called “rules” of improv. This is a refreshing and practical guide, especially for those who feel boxed in by traditional structures.
Why “Truth in Comedy” Stands the Test of Time
What gives “Truth in Comedy” its staying power in an evolving improv world? It’s the philosophy behind the method.
Most improv books teach skills. “Truth in Comedy” teaches values. It doesn’t just explain how to do a Harold—it explains why being truthful is funnier, richer, and more resonant than trying to “perform.”

What Beginners Should Know Before Reading
“Truth in Comedy” is accessible, but its full depth is revealed when paired with practical experience. If you’re just starting out, consider:
Taking an improv class while reading.
Doing the exercises with friends.
Watching long-form improv performances online (look up “TJ & Dave,” “Middle Ditch & Schwartz,” or “ASSSSCAT”).
The book isn’t a joke-writing guide or a how-to-be-funny manual. It’s about truth, vulnerability, and listening—skills that benefit everyone, not just performers.
Final Thoughts: The Right Book for Your Journey
