If a book musical asks “what happens next?” and a jukebox musical asks “do you recognise this?”, a concept musical asks something completely different: what does this feeling, this idea, this moment in a life actually mean? I think it’s the hardest of the three formats to explain simply, which is exactly why I wanted to write this properly rather than reduce it to a one-line definition.
What Is a Concept Musical?
The Core Definition
A concept musical is a musical built around a unifying idea, theme, or structural device rather than a continuous, chronological plot. Instead of following a single story from beginning to end the way a book musical does, a concept musical organises its scenes and songs around a central concept, and uses the music to examine that concept from multiple angles rather than to advance a linear sequence of events.
This is a genuinely different way of building a show. In a book musical, you could in theory describe the plot to someone in a few sentences and they’d understand the shape of the evening. In a concept musical, describing the plot often barely tells you anything, because the plot was never really the point.
Where the Term Comes From
The phrase itself has a surprisingly specific origin. In 1968, critic Martin Gottfried reviewed Zorba, directed by Harold Prince, for the New York Times, and wrote that “conception is the big word here, it is what is coming to replace the idea of a book.” That single review is widely credited as the moment the term “concept musical” entered common use, specifically to describe the way Prince was organising shows around a directorial idea rather than a traditional script-first structure.
A Brief History of the Concept Musical
The Precursors
Before the term existed, the groundwork was already being laid. Man of La Mancha (1965) and Cabaret (1966) both experimented with structuring a show around a theme and a framing device rather than pure chronological storytelling, and Hair (1967) pushed further still, abandoning conventional plot almost entirely in favour of a loose structure built around the counterculture itself as the subject.
Company and the Genre’s Real Arrival
The concept musical truly arrived, in the form we’d recognise today, with Company in 1970. Stephen Sondheim wrote the music and lyrics, George Furth wrote the book, and Harold Prince directed. Rather than following a continuous story, the show presents a loosely connected series of vignettes about marriage and commitment, all orbiting around a single unmarried man, Robert, on his 35th birthday. Company opened at the Alvin Theatre on Broadway and won the Tony for Best Musical, proving immediately that audiences would embrace a show that broke nearly every rule of how a musical was supposed to be built.
Why Sondheim and Prince Matter So Much to This Format
I don’t think it’s an exaggeration to say the concept musical as a genre is inseparable from the Sondheim/Prince partnership, alongside choreographer-director Bob Fosse. Beyond Company, the pair went on to create Follies and Pacific Overtures, both of which structured entire evenings around a theme (the death of an art form, the collision of two cultures) rather than a conventional plot. These shows weren’t commercial sure things in the way a book musical with a familiar story could be; they demanded an audience willing to follow an idea rather than a character’s journey, and the fact they succeeded at all changed what people believed a musical could do.
Bob Fosse’s Parallel Contribution
Alongside Sondheim and Prince, choreographer-director Bob Fosse was developing his own strand of the format through staging and movement rather than through Sondheim’s lyrical density. Pippin (1972) wraps its coming-of-age story inside the framing device of a travelling troupe of performers putting on a show about Pippin’s life, constantly reminding the audience they’re watching a performance about a performance. Chicago (1975) goes further still, structuring its entire true-crime story as a vaudeville revue, with each major plot beat delivered as a self-contained musical number in a presentational style rather than as a naturalistic scene. Fosse’s contribution to the concept musical is really about proving that staging and choreography could carry as much conceptual weight as Sondheim’s lyrics did.
Why the Concept Musical Was Initially So Divisive
Critics Who Wanted a Story
I think it’s worth being honest that the format wasn’t universally welcomed when it first emerged. Some critics and audiences in the early 1970s found shows like Company cold or unsatisfying precisely because they withheld the thing musical comedy had always promised: a clear story with a beginning, a middle, and a resolved end. Following an idea instead of a character’s fate is a different kind of theatrical contract, and not every audience member in 1970 had signed up for it.
Why It Won People Over Anyway
What changed people’s minds, I think, was simply how emotionally effective the format turned out to be once audiences adjusted their expectations. A Chorus Line became one of the longest-running shows in Broadway history specifically because audiences responded to its honesty, even without a conventional plot to hold onto. The format succeeded not despite its structure but because of it: stripping away plot mechanics left more room for raw, direct emotional address.
What Actually Makes a Show a Concept Musical?
Structure Over Chronology
The clearest tell is structural. If you can lay out the events of a concept musical on a timeline and have that timeline meaningfully represent the show, it probably isn’t a concept musical. If the show instead circles a theme, returning to it from different characters’ perspectives or different moments without a strict before-and-after logic, that’s the format at work.
Theme as the Real Protagonist
In a concept musical, the theme itself often does more dramatic work than any individual character. Company isn’t really “about” Robert in the way Guys and Dolls is about Sky Masterson; Robert is more of a lens the show uses to examine marriage and commitment from multiple angles through his married friends. The theme is the throughline. The character is the vehicle.
Staging and Design as Structural Tools
Concept musicals frequently use staging itself to express the concept, not just the script. A Chorus Line is staged almost entirely on a bare rehearsal stage with a mirrored backdrop, a design choice that isn’t just visually striking, it’s a structural statement about exposure, vulnerability, and the absence of anywhere to hide. The set is doing conceptual work that a book musical would usually leave to plot and dialogue.
Concept Musical vs Book Musical vs Jukebox Musical
Here’s how the concept musical compares to the other two major structural formats I’ve written full guides to.
| Structural Element | Concept Musical | Book Musical | Jukebox Musical |
|---|---|---|---|
| Organising principle | A unifying theme, idea, or structural device | A linear, chronological plot | A pre-existing song catalogue |
| Source of the music | Original score written specifically for the show | Original score written specifically for the show | Pre-existing, previously released songs |
| Narrative framework | Often non-linear, episodic, or vignette-based | Linear, cause-and-effect | Varies (biographical, fictional, or none) |
| What the audience follows | An idea examined from multiple angles | A character’s journey through events | Familiar songs, however they’re framed |
| Risk profile for the creative team | High; demands audience trust in an idea, not a story | Moderate; story has to earn its own momentum | Lower; familiarity does a lot of the work |

Case Studies: How the Format Actually Works on Stage
Company
This remains the cleanest demonstration of the format. Every vignette, every married couple Robert visits, exists to add another facet to the show’s central question about whether commitment is worth its cost. Remove the chronology entirely (and productions have reordered scenes between revivals without damaging the show) and it still works, because the show was never relying on chronology to begin with.
A Chorus Line
I think this is the format at its most emotionally direct. The “concept” is the audition itself: seventeen dancers fighting for eight spots, each given a moment to reveal who they are beyond the choreography. The show barely has a plot beyond “will I get the job,” but it doesn’t need one, because the real subject is what it costs to want this career badly enough to keep showing up to room after room of rejection.
Hadestown
This one’s a useful complication, and I think it’s worth addressing directly because the word “concept” shows up in its history in a different sense that can confuse people. Hadestown began life as a concept album in 2010 (meaning an album built around a unified theme or story, the music industry’s use of the word, not the musical theatre structural term) before composer Anaïs Mitchell developed it into a stage show retelling the Orpheus and Eurydice myth alongside Hades and Persephone’s. On stage, it does function as a concept musical in the theatrical sense too: it’s structured around a sung-through meditation on love, poverty, and inevitability, using the myth as the lens rather than as a plot to be followed beat by beat. It’s a good example of how the word “concept” gets used loosely across different contexts, and why I think it’s worth being precise about which meaning you’re using.
Hamilton
I’d argue Hamilton sits closer to the book musical end of the spectrum than people often assume, since it does follow a clear chronological life story, but its structural ambition (the sung-through hip-hop framework, the deliberate use of repeated musical motifs to comment on the story rather than just narrate it) borrows enough from the concept musical tradition that it’s worth mentioning here as a hybrid case. Lin-Manuel Miranda has spoken about Sondheim’s influence directly, and you can hear it in how the show uses music to editorialise on its own events, not just describe them.
Chicago
Bob Fosse and John Kander and Fred Ebb’s vaudeville framing device is the clearest possible demonstration of staging-as-concept. Every major event in Roxie Hart’s trial is delivered as a self-contained presentational number, performed directly to the audience as though it were a music hall act, rather than as a naturalistic scene the audience watches unfold. The concept, that celebrity and crime are essentially showbiz, is baked into the structure itself: you’re never allowed to forget you’re watching a performance about performance.
Is the Concept Musical Harder to Stage as an Amateur Society?
I think the honest answer is: differently hard, not necessarily harder.
Audience expectations need managing. A society programming Company or A Chorus Line should be upfront in marketing that this isn’t a conventional plot-driven night out. Audiences who arrive expecting a clear story can feel adrift if nobody’s prepared them for the format.
Ensemble strength matters enormously. Many concept musicals (A Chorus Line especially) ask every member of a large ensemble to carry a genuine individual moment, rather than letting a few leads carry the emotional weight. That’s a real test of depth across a cast, not just at the top of the bill.
Staging can be simpler than you’d expect. Because the format often relies on a directorial idea rather than elaborate scenery, some concept musicals are genuinely more achievable on a modest budget than a book musical demanding multiple realistic sets. A Chorus Line’s bare stage is a perfect example: the simplicity is the point, not a compromise.
Vocal and acting demands tend toward the character-actor end. Concept musicals often reward performers who can hold a single, sustained emotional truth through a song rather than performers built for big, showy belting. That can suit societies with strong actor-singers who might not have traditional leading-role voices.
A Common Misconception Worth Clearing Up
I think the single most common mistake people make with this term is assuming that because Stephen Sondheim wrote a show, it must be a concept musical. It isn’t that simple. Sondheim wrote plenty of shows that are genuinely book musicals: Sweeney Todd follows a clear, linear revenge plot from beginning to end, and Into the Woods, despite its layered fairy-tale structure, still follows its characters through a continuous chronological story. Sondheim’s name is a strong signal that a show will be structurally ambitious and lyrically dense, but it isn’t a guarantee that the show abandons plot for theme. The format is defined by structure, not by who happens to have written the score.
How to Tell If a Musical Is a Concept Musical
A practical test, the same way I approached this for jukebox musicals: ask whether you could remove the chronological order of the scenes without damaging the show’s meaning. If the answer is yes, or close to yes, you’re likely looking at a concept musical. If reordering the scenes would make the story incomprehensible, you’re almost certainly looking at a book musical instead, however thematically rich it might also be.
Frequently Asked Questions About Concept Musicals
What is a concept musical?
A concept musical is a musical structured around a unifying theme or idea rather than a linear, chronological plot. Songs and scenes examine that central concept from multiple angles rather than advancing a continuous story.
What was the first concept musical?
Company, which opened on Broadway in 1970 with music and lyrics by Stephen Sondheim, book by George Furth, and direction by Harold Prince, is widely credited as the show that established the format, though Cabaret (1966) and Hair (1967) laid important groundwork before it.
Where does the term “concept musical” come from?
Critic Martin Gottfried used the word “conception” in a 1968 New York Times review of Zorba, directed by Harold Prince, to describe a directorial approach replacing the traditional idea of a “book.” The term stuck.
Is Hadestown a concept musical?
Yes, in the musical theatre structural sense. It began life as a 2010 concept album (a different use of the word “concept,” referring to a themed record) before being developed into a stage show structured around a sung-through meditation on its central myth.
Is A Chorus Line a concept musical?
Yes. It’s structured around a single audition rather than a chronological plot, using that framing device to give a large ensemble of dancers individual moments of revelation.
Are concept musicals harder to stage as an amateur society?
Differently hard rather than necessarily harder. Audience expectations need managing, ensemble strength matters more than usual, but staging demands can actually be simpler than an elaborate book musical.
