Q: 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 bourrée to the accompaniment of the cabrette (a bellows-blown bagpipe locally called a "musette") and often the vielle à roue (hurdy-gurdy) in the cafés and bars of the city. Parisian and Italian musicians who played the accordion adopted the style and established themselves in Auvergnat bars especially in the 19th arrondissement, and the romantic sounds of the accordion has since become one of the musical icons of the city. Paris became a major centre for jazz and still attracts jazz musicians from all around the world to its clubs and cafés.

A: What style of french music became populars in the 1870sto 1880s?

Q: The French Army consisted in peacetime of approximately 400,000 soldiers, some of them regulars, others conscripts who until 1869 served the comparatively long period of seven years with the colours. Some of them were veterans of previous French campaigns in the Crimean War, Algeria, the Franco-Austrian War in Italy, and in the Franco-Mexican War. However, following the "Seven Weeks War" between Prussia and Austria four years earlier, it had been calculated that the French Army could field only 288,000 men to face the Prussian Army when perhaps 1,000,000 would be required. Under Marshal Adolphe Niel, urgent reforms were made. Universal conscription (rather than by ballot, as previously) and a shorter period of service gave increased numbers of reservists, who would swell the army to a planned strength of 800,000 on mobilisation. Those who for any reason were not conscripted were to be enrolled in the Garde Mobile, a militia with a nominal strength of 400,000. However, the Franco-Prussian War broke out before these reforms could be completely implemented. The mobilisation of reservists was chaotic and resulted in large numbers of stragglers, while the Garde Mobile were generally untrained and often mutinous.
