After 1840, as in so many other villages in the district, a new industry arose, "Wandermusikantentum", which saw local musicians travel the world over plying their trade. Men – it was most often men – went abroad in groups of 5 to 15 and earned their living by playing music. Mostly they had firm engagements at spa hotels or bathing beaches. Early on in "Wandermusikantentum", the musicians sometimes also took jugglers along with them. They could sometimes also be hired as circus orchestras. In the United States, they travelled on pleasure steamers on the country's great rivers. In the early days, the musicians went to neighbouring countries such as France, Belgium, the Netherlands and Switzerland. After the Franco-Prussian War (1870-1871), they no longer went to France, though, a country still seething at the loss of the war, and of a sizeable piece of territory, Alsace-Lorraine, to the newly minted German Empire. Instead, they focused their efforts on Eastern Europe. It was only in the 1880s that some of these local musicians became bold enough to visit the United States, but before the turn of the century, there were few parts of the world where the "Wandermusikanten" had not trodden. It was not unheard-of for them to seek work in South Africa, Australia or Southeast Asia. How long they were away from home depended to a great extent on how far away they went. One of their American tours, for instance, might last 20 months, while those who went to make music in Australia might not see home for five years. Jobs within Europe, however, allowed them to work only nine months of the year and return home for the winter. In 1908, there were 102 musicians living in Jettenbach. They only interrupted the plying of their craft when they were forced to – by the First World War. Many were away from Germany when this broke out, and found themselves in countries that had suddenly become hostile towards Germans. In the United Kingdom, Australia and the United States, many were interned. After the war, there was a great decline in this industry, and then, after Adolf Hitler and the Nazis started the Third Reich in the 1930s, the industry was forsaken, utterly.
