Each country in the world, in some cases each region, district and community, has its own folk music style. The sub-divisions of folk genre are developed by each place, cultural identity and history. Because the music is developed in different places, many of the instruments are characteristic to location and population—but some are used everywhere: button or piano accordion, different types of flutes or trumpets, banjo, and ukulele. Both French and Scottish folk music use related instruments such as the fiddle, the harp and variations of bagpipes.
