The Steel Band was invented around the time of World War II. Its home is Trinidad and its roots are from Africa. When the British colonial authorities banned African drumming, the people made music from bamboos which they thumped on the ground. and they created "Tamboo Bamboo Bands". Between the 1930s and 1945, biscuit tins, hubcaps and empty oil drums became a new sort of drum - steel, with distinct notes hammered into the surface. The steel banders call the music Pan and the oil drums on which it is played were called "pans". Trinidadians have always believed that music should be made with whatever came to hand. The Trinidadians also claim that the steel drum is the only non-electronic musical instrument invented in the 20th century.
