The tapou drum is pronounced as "THAPPU". This drum is an all purpose drum in Tamil Nadu, and it is not restricted to the Tamils, but is primarily used by the Telugu speaking people, Kannadigas, and Keralites (Malayalees). So basically, this drum is a south Indian drum used for funerals (mainly Tamil Nadu), folk dances, politics, and other auspicious and inauspicious occasions. Actually this drum is associated with lower caste Tamils known in India as "Dalits", or actually in Tamil as "Paraiyars", and they are the ones usually playing the goatskinned thappu for the occasions. In Tamil Nadu, a thappu ensemble is called "thappu melam", and melam in Tamil means drum orchestra. Usually a thappu band consists of a few thappus, a few drums you guys call "tassa", and a bass drum. Thappu is not just the main drum, we have "urumi" which is the most distinctive and most popular Tamil drum with its whirring sound to get people into transes, its commonly used in the Tamil folk culture, for folk dances, and is associated with amman, and other samy deities. So there you have it, thappu is NOT the main drum of Tamils, we are the drumming masters of India, we have a variety of drums. I'm really shocked that urumi and pambai was not brought to the Caribbean, maybe because its more simple to make thappu? Who knows...
