"In 1883 the government introduced a Music Bill which prohibited the playing of drums between the hours of 6am to 10 pm except with a police license, and after 10 pm they were absolutely prohibited. The bill was withdrawn and the Ordinance II of 1883 took its place. The Ordinance tried to put down drum dances by making every owner or occupier responsible for crowds assembling in their yards, and prohibition on the use of African drums continued. This triggered musicians to turn to tambour-bamboo bands which flourished after the early 1880s as accompaniment for calypsos and for Carnival music"; the use of the tambour-bamboo ignited the calypso music that began to dominate the music of Trinidad.
