The people of Madagascar believe that the soul of the dead always exists. They maintained the tromba ritual to call the ancestral spirit of the royal lineage of the Sakalava tribe.
Through rituals, the late kings will convey the message to their descendants or to the whole nation. To date, people in northwestern and southern Madagascar still maintain this ceremony.
Usually the soul call ceremony takes place at night, outdoors or a specific sacred place. Anyone can attend but must remain silent throughout the ceremony. The performer is the musician, intoxicated in the drum and the accordion sound opens the door to the afterlife. Supporters can be one or more families or tribes.
The tromba begins with slow music or a sound of resentful music, then a quick rhythm throughout the ceremony. Soul callers always sit in the middle of the audience and have to really concentrate. They wear lambahoany costumes with traditional silk fabrics.
As the pace of music increased, soul callers began to move more, they twitched and struggled like the actors in horror movies. Even they could not control their bodies, eyes rolled up and the voice changed, turning into the voices of the deceased. They are said to have been involved in one or more lives, both women, men, elderly or children, according to Generation Voyage.
Next, the soul caller mumbles the messages that people believe to be the soul in the underworld. Believers of tromba ceremonies believe that the messages they receive from the deceased must be respected and followed.
The souls of the deceased always exist in the Sakalava mind, existing through tromba. Although they are no longer in life, they still care about their future children and their country. Therefore, the people of Madagascar feel that asking for advice from the deceased is necessary in life.
