Charm is the main ingredient of the more sentimental Viennese operetta, and it usually submerges the rarer shaft of social comment. The younger Johann Strauss made operetta an international entertainment by an expert blend of charm and craft, and his Die Fledermaus (1874; The Bat) remains a classic of its kind. A second generation in this tradition was chiefly distinguished by Franz Lehár, whose Die lustige Witwe (1905; The Merry Widow) represents the genre at its peak of romantic elegance, demonstrating a style and craftsmanship that seems in serious danger of being lost altogether.

Such operettas remain current in today’s musical theatre mainly as an indulgence of musical and emotional nostalgia. Their popular style enabled them to take root and flourish far from their native territories, including transplantation to the United States. The indigenous tradition of the U.S. stage musical, already mentioned, first had to compete with European-style operetta. That the latter keeps a tenacious hold on popular affections is demonstrated by figures listing Rudolf Friml’s Rose Marie (1924) and Sigmund Romberg’s The Desert Song (1926) as the most frequently performed works in U.S. musical theatre, in terms of both amateur and professional performances.

Zarzuela

Spain was a prominent exception to the wide dissemination of operetta, preferring instead the flourishing native variety of zarzuela. This form customarily incorporates regional songs and dances, sometimes with traditional rather than original music. It continues to some extent as a staple fare in Spanish musical theatre, although the general contemporary trend toward a more universal style of musical expression has meant that the younger Spanish composer has shown much less interest in the zarzuela form as an outlet for his musical imagination.

The Romantic zarzuela has little resemblance to the aristocratic and courtly character of its 17th-century namesake and emerged with French and Viennese operetta during the 19th century. It divided into two forms—the zarzuela grande in three acts, equivalent to romantic operetta, and the género chico in one act, invariably comic, usually satirical, employing the broadest musical vernacular, and verging on revue. In the former category, the names of Francisco Barbieri, Amadeo Vives, and Federico Moreno Torroba are probably the most significant representatives of their respective generations.

The Spanish character and language of the Romantic zarzuelas made them exportable to Central and South America, where they became a model for the limited indigenous musical theatre. The South American centres are otherwise dominated by imports or imitations of the Italian opera tradition or used as transit bases for the latest North American stage musical on its theatrical circumnavigation. Certain examples of the Spanish zarzuela, such as Moreno Torroba’s Luisa Fernanda (1932), have achieved popular success in Latin American countries, where local contributions to the genre have notably been made by Juan Bautista Massa in Argentina, Andrés Martínez Montoya in Colombia, Luis Delgadillo in Nicaragua, and Teodoro Valcárcel in Peru.

Oriental musical theatre

Theatre music generally serves different purposes in non-Western idioms—usually adding dimension and perspective to song and dance, indicating symbolic associations, suggesting mood, and even inducing a desired response in an audience. Most Oriental streams of music divide between popular music of a folk character and a more sophisticated style for a cultured elite. The distinction is often less clearly defined than in Western music and is now not so firmly maintained in the wake of recent political and social changes.

China

The classical Peking opera (ching-hsi) in China is a form of musical theatre in which music is one among several elements rather than a governing factor, as in Western opera. The vocal writing alternates between styles broadly equivalent to recitative and song, distinguished by a forced high falsetto tone required from the male singers. A less stylized variety is the all-female yüeh ch’ü, in which natural singing voices perform musical plays in realistic and decorative scenery, and the Manchurian P’ing Hsi, which has developed into an operetta-like equivalent, with traditions and subjects derived from strolling players and folk legends.

Since 1964 the performance of classical Peking opera in Communist China has been mainly restricted to festival occasions (although state-sponsored schools continue to train performers especially for it). More emphasis has been put on entertainments closer to Western musicals, involving contemporary dialogue, everyday dress, and less stylized music. As a popular form of musical theatre it has been turned to political and social advantage with a new and adapted repertory of dramatic ballets and musical plays, bearing such titles as Taking Tiger Mountain by Strategy and The Red Detachment of Women.

Japan

Music is as much a regular part of theatre performance in Japan as it is in China. The highly formal tradition of Japanese drama incorporates music as an integral feature, usually performed by flute, a variety of stringed instrument called the samisen, drums, and singers. The music varies in content and character with the subject of the play and obeys detailed melodic rules—especially in the central dance episode designed to reveal the spirit of the play’s principal character. A less formal counterpart, the Kabuki theatre, has almost as impressive an ancestry as the Nō and continues to be widely performed, with music used to indicate period, place, time, or mood and often functioning by phrase association like the principle of leading motives in Richard Wagner.

India

Japanese theatre also incorporates music dramas of Indian origin, and the Indian theatre tradition is a full combination of poetry, music, dance, and symbolism. The music is often interpolated rather than specially composed and is likely to be drawn from the repertory of widely known songs without aiming at a high classical standard. The close association of music with drama in Indian culture has been carried over into Indian film, which cannot hope to enjoy wide success among its modern audiences unless it is liberally embellished with songs and other forms of music.

The history of theatrical music

Formative period

What is thought to be the oldest document of musical history depicts a man wearing an animal mask, manipulating what is possibly a form of musical bow, and dancing in the wake of a herd of reindeer. This is a prehistoric cave painting dating from the Stone Age, discovered at Ariège in France. Masks are tangible signs of that transfer of personality on which every form of theatre is based and in which song and dance have participated since the dawn of communication and animated ritual. Music in dramatic entertainment reached early peaks of development in European and Oriental cultures in, respectively, the ancient Greece of Homer and, some centuries later, the Chinese classical drama.

Descriptive evidence of the earliest Greek theatre indicates that music, mostly sung by a chorus, was essential but not continuous. At drama festivals the poet wrote his own music (as well as being actor, producer, and choreographer), probably based on some kind of traditional repeated formula. Later Greek theatre, after the fall of Athens (404 bc), initiated both the repertory system and a category of musicians trained more highly than the populace. Amateur and professional became separated for the first time, and increasing sophistication brought about its counterpart in popular pantomime expressed in song and dance, often satirical or bawdy in character.

The Roman musical theatre derived directly from the Greek, ousting a short-lived native form with Etruscan actors who also danced to pipe music. Latin versions of the Greek theatre with music were supplemented by a Roman variant of the pantomime as a dramatic solo dance with chorus and orchestra. It implied some prior knowledge on the audience’s part of the subject and the dance vocabulary. Amphitheatre shows of gladiatorial contests were regularly accompanied by music, sometimes involving up to 100 horn blowers and 200 pipers, as well as such extra devices as water organs.

About the time the Roman theatre flourished, an Oriental equivalent emerged in China from ritual ceremonies that came to be repeated for their entertainment value. The puppet theatre was a significant intermediate stage in this process, and the forms evolved into different styles of entertainment for courtier and commoner. Strings, flute, and handbells accompanied the songs and dances in upper-class entertainments; a form of mouth organ replaced the bells in shows for the common people. By the time of the Sung dynasty (ad 960–1279), from which the earliest written music survives, a type of musical variety theatre, the tzarjiuh, was widely popular.

The Chinese classical opera tradition has already been mentioned as a modern form of musical theatre. It first developed during the Yüan dynasty (1206–1368) and reached its peak of style and classical form in the Ming period (1368–1644). Its evolution was accompanied by a less formal counterpart based on the dramatization of folk songs linked by a thin narrative plot (Chueichang). The full-scale opera and its regional variants remained the most significant form of Oriental musical theatre until the modern post-revolutionary times, but throughout the Far East the indigenous forms of music have always played a prominent part in theatrical presentations.

In Europe the vestiges of Greco-Roman culture were submerged by the early Christian Church. By the 6th century the church had suppressed drama and adapted pagan rituals to its own liturgical purposes. A small flame of musical theatre was left burning only in the form of religious ceremonial (for example, in the mass). Festive religious celebrations eventually expanded into the liturgical music drama that slowly developed from about the 10th century. This brought in its wake the equally religious “mysteries” and miracle plays of the Middle Ages in Europe, which were performed in the vernacular instead of in Latin, had a strong musical element, and, in due course, developed a secular counterpart.

In a pattern that was to repeat itself after the birth of opera 200 years later, the secular theatre in the Middle Ages established itself either as lighthearted interludes in serious moralities or as deliberate parody tolerated by the church as a safety valve to consistent piety. The annual Feast of Fools in 15th-century Paris, for instance, incorporated an obscene parody of the mass performed in song and dance within the church. By the year 1400 numerous comedies and farces had appeared, usually performed on festive occasions in aristocratic houses or on open stages in municipal squares.

These plays often employed musical forces comparable to those of the religious plays and used them for similar purposes. Choirboys from the church sometimes took part, but surviving texts suggest that there was little choral music as such. The individual actors incorporated parts of songs chanted monophonically to embellish or heighten the dramatic effect, and dancing to specific instrumental music also had a regular place in the entertainment. Professional musicians might be hired and might also be required to act; the constituent parts of the entertainment varied widely from place to place.

The fact that, except for songs, documents of the period contain almost no music directly linked with the theatre is thought to indicate that very little original instrumental music was written for theatrical purposes at this time. Whatever was suitable for weddings, banquets, and other feasts perhaps served a theatrical purpose just as well. Musicians probably had little or no acquaintance with musical notation and played pieces from their regular repertory. These seem to have included arrangements of vocal melodies as well as dance tunes, among which the play texts most frequently identify basses-dances and branles.
