The emotional core of the musical is the engine that propels the drama and travels the emotional distance the characters travel. This core should grow and build throughout the acts (not a piece of Act One and a piece of Act Two, but rather an entire piece that flows from one act into the next) until it reaches its climax. The events should unfold so that we grow from curious about the characters to caring about them and finally, release. In the first moments of a musical, there is usually some action, some slight challenge that foreshadows what’s to come and engages our initial sympathies.
Most of this building, of course, comes from the ratcheting up of the emotional stakes from one act to the next, but it also relies heavily on the careful plotting of turning points that put characters in a position where they must face their inability to go backwards and move forward into a decision that cannot be reversed. Typically, we see the “want” or the “disruption” in act one, the “question” of the story clarified and ready to carry us through; then act two complicates that question with challenges and discoveries that ratchet up the tension for all involved until everyone hits their various walls.
In the third act, that resolution is then rewarded in a way that feels fulfilling but also true to the difficult journey that it took to get there. The emotional relief that comes with some level of a happy ending is really found in people’s changed perspectives, even if their situation isn’t necessarily all that different. The last musical numbers are often recapitulations, where there is time to sit and reflect quietly or to belt out a reprise of the beginning, to show how far they’ve come emotionally. The cyclical but still forward-moving nature of the story gives the sense of an ending but not necessarily in a neat, tidy way that means a finale has to end immediately with its final notes ringing in our ears.
Doing all of this, however, requires control. You can’t have your characters be so broken or cloying that they turn off the viewer. You have to space out dramatic moments with comedowns and spectacle. There has to be a range of emotional displays and recognitions, from one-on-one, private affirmations to grand, whole-group confessions. And there needs to be a steady return to the core emotional exploration lest the series wander and make these emotional scenes feel disconnected from the rest of the story.
Finally, when done right, an emotional arc makes the musical not just fun but emotionally resonant, allowing people to experience catharsis, connection, and hope. It demands precision in the shaping of each moment but also great compassion for the audience, as creators need to intuit how people will react to every single moment, every emotional turn of the musical. When done right, it creates a story that the audience doesn’t just watch, but embodies, another testament to the power of musical theatre.
