Les Miserables is a typical musical with British and American styles, and this kind of play is called "Musical Theatre". There is no strict restriction on the singing style of this musical, which can be bel canto and popular, and it is set completely according to the needs of the plot characters. The music style is also case by case, for example, LM is the style of symphony orchestra accompaniment, while Mamma Mia! They are totally popular electro-acoustic bands, but the same thing is that this kind of drama emphasizes drama conflict and drama logic, and some Legato music follows this principle. The reason why Les Miserables has become a classic drama of musicals is closely related to the development of musicals in the 2th century, in addition to its broad and classic humanistic background. Early musicals were born in bars and other places of song and dance entertainment. It is a style of mixing drama, dance, music and poetry in various ways. Classical music and popular performances are the sources of musicals, which originally came from Europe rather than Broadway. From Strauss's popular music to French operetta to mass entertainment, European vaudeville theaters provide more lively performance space for the birth of musicals. When people's taste has changed from the performing arts such as opera, the musical, which is full of appreciation and accords with the nature of escape and freedom, has become a new outlet for people's feelings. In the United States, the fusion of jazz, rock and fashion singing and dancing has formed Broadway musicals, which appeared in the Hollywood musical Desert Love Song in the 192s and 193s. Her flourishing period began in the 196s, and has fully demonstrated her unique comprehensive and creative power-integrating multiple artistic styles such as opera, symphony jazz, rock and roll, such as conductor Bernstein's west side story. Music, singing and dancing and industrialized production of dance beauty have always gone hand in hand, which has become a major feature of musicals. In production, the concept of market mechanism has been strengthened, and performance and commercial profit have always been integrated, which has become an important factor for the continuous success of musicals.
Musicals require that the appearance and temperament of the actors must conform to the role, and they must be good at singing and dancing, know how to perform, and have a solid foundation in music, but they are often informal in singing. In Les Miserables, Colm Wilkinson, the actor of jean valjean, showed a high level of bel canto. But when the love is deep, he sings very exaggeratedly and casually.
