Double sided drums in a similar style to a Tambora can be found in many parts of Africa and hugging the coast of Asia - South Arabia, India and all the way eastward into SE Asia. They also play a tambora ( along with the bagpipes ) in Oman. Being mostly desert, Oman looked out to the ocean, and made it's fortune in shipping. They borrowed most of their instruments from the peoples they encountered in trade.
These drums became popular in the Indian Ocean and East African shipping routes and were played especially for ocean faring music, to send off ships or welcome them back home, or to hoist the sails. It became Oman's main style, and incorporated
a lot of influence from Africa. Today many of the top musicians in Oman are of African descent. It's no wonder,
Oman based their trading headquarters in Zanzibar, off the coast of Tanzania from 1698-1856.
They overthrew the earlier Portuguese traders, and controlled some of the slave trading headed toward the Caribbean
from Zanzibar and Mozambique. I've attached some photos I took at an Omani festival in Washington DC a few years ago.
I got to accompany this drum group, playing a steady 6/8 with sticks on a metal tray, loosely bolted down to a bread cutting board.
These guys could play all of their traditional rhythms as well as the most up to date hip-hop.
