The nineteenth century infatuation with opera by residents of Izmir, Istanbul, and Thessaloniki is grounded mainly in their attempt to take part in a global "civilizing mission." The middle classes and the administration intended but often failed to educate the lower classes to properly behavior during theater performances, refraining from smoking, eating, unpleasant bodily movements or ill-timed displays of veneration. Nonetheless, all these and also violence were not uncommon at the opera house. Moreover, opera aficionados wishes for a "one world" of global stage entertainment, for a cultural exchange with Western and Central Europe. Unfortunately, Western interest in Eastern music and narratives came to an end in the 1820s, whereas Eastern interest in Western performances gained momentum later.

When Franz Lehár’s Viennese operetta The Merry Widow arrived London in 1907, it was not only one of the most remarkable West End hits but also the beginning of a new age of global entertainment. The reception took place worldwide and overcame national traditions to establish a new international show business in the early twentieth century. In consequence a cross-cultural exchange emerged confirming the ‘birth of the modern world’ at that time. Along with Lehár, a new generation of composers propagated the new style on the Continent, for example, Oscar Straus, Leo Fall and Emmerich Kálmán. In the decade before World War I, Viennese operettas dominated the repertory of the Western world. Balancing the ‘local’ and ‘global’ was an important aspect of their achievement, so it was no coincidence that all those composers originated from the Habsburg Empire. Thus, Lehár grew up as a son of a Czech-born, German-speaking military bandmaster and of a Hungarian mother, spending his childhood in seven different cities of Austria-Hungary. Life was similar for Leo Fall, who furthermore was Jewish like Oscar Straus, and Emmerich Kálmán. But they all worked in Vienna, the experimental laboratory for the arts generally and popular music especially.
