Input: Consider Input: Bal-musette is a style of French music and dance that first became popular in Paris in the 1870s and 1880s; by 1880 Paris had some 150 dance halls in the working-class neighbourhoods of the city. Patrons danced the bourree to the accompaniment of the cabrette (a bellows-blown bagpipe locally called a "musette") and often the vielle a roue (hurdy-gurdy) in the cafes and bars of the city.

Paris became a major centre for jazz and still attracts jazz musicians from all around the world to its clubs and cafes.

Input: Consider Input: In the 1990s, marked by the liberalization of language development and mother tongue movement in Taiwan, Taiwanese Hokkien had undergone a fast pace in its development. In 1993, Taiwan became the first region in the world to implement the teaching of Taiwanese Hokkien in Taiwanese schools. In 2001, the local Taiwanese language program was further extended to all schools in Taiwan, and Taiwanese Hokkien became one of the compulsory local Taiwanese languages to be learned in schools.

In 2007, the Ministry of Education in Taiwan also completed the standardization of Chinese characters used for writing Hokkien and developed Tai-lo as the standard Hokkien pronunciation and romanization guide. A number of universities in Taiwan also offer Hokkien degree courses for training Hokkien-fluent talents to work for the Hokkien media industry and education. Taiwan also has its own Hokkien literary and cultural circles whereby Hokkien poets and writers compose poetry or literature in Hokkien on a regular basis.
