What Is a Book Musical?

Wikipedia says the "book musical" has been defined since the 20th century as a musical play "where songs and dances are fully integrated into a well-made story with serious dramatic goals and which is able to evoke genuine emotions other than laughter." The same page states that "the three main components of a book musical are its music, lyrics and book."

What Does "the Book" Mean?

Wikipedia states that the book, or script, of a musical "refers to the story, character development and dramatic structure," including the spoken dialogue and stage directions. The term can also cover the dialogue and lyrics together, which are "sometimes referred to as the libretto," Italian for "small book."

Where Do the Songs Fit?

According to Wikipedia, "a book musical is usually built around four to six main theme tunes that are reprised later in the show," though it sometimes consists of songs that are not linked musically. "Moments of greatest dramatic intensity in a book musical are often performed in song," the same page states. "In a book musical, a song is ideally crafted to suit the character (or characters) and their situation within the story," it adds, though "there have been times in the history of the musical (e.g. from the 1890s to the 1920s) when this integration between music and story has been tenuous."

How Is It Different From Other Forms?

A concept musical describes a tendency rather than a fixed formula: a core idea or staging framework can sometimes shape the audience's experience as much as the plot does; see our guide to concept musicals. A sung-through musical relies mainly on song, with little or no spoken dialogue, though that is not a strict ban on spoken words; see our guide to sung-through musicals. A jukebox musical gives existing songs, usually written apart from any stage plot, a new theatrical setting; see our guide to jukebox musicals.
