Dammam Dammam is a group of double-sided drums and they are played by the percussion stick and played by the direct hand and plectrum. Dammam exists in Bushehr in three sizes, which also have three different functions. Ordinary Dammam, which is available in groups of four, is the simplest type of Dammam. Dammam Ghambar is slightly larger than regular Dammam and is used in two numbers along with four ordinary Dammam. Dammam Ashkon is smaller than the others and only one is used in group playing. History: About 4,000 years ago, traces of drums were found in ancient Egypt. The drum was played as a magical tool to ward off misery and evil or to summon pure spirits. It has also been used for news, announcing and dancing. Dammam, like its ancestors, was played for these reasons. The rope around Dammam is Y-shaped and is a similar to African and Indian percussion instrumenr, and its name is derived from their sound. structure: Body: The cylindric body of Dammam, which lacks skin and rope, is called a pipe. The pipe is made of a piece of wood that is usually is the trunk of a tree and is emptied inside. Then polish the surface with veneer oil to smooth the outer surface of the body and have a shaped appearance. Round rings: Rings made of metal rods or bamboo straws, open straws or bamboo around the body. In order to twist the reed around the body, the reed is soaked to soften it, then it is rounded and the two ends are tied with a string, which is called a spotting. Twisting the reed around the body continues until the diameter of the reed reaches about three centimeters. The rings around the body, which are four pairs in total on both sides, are called chambers. The Chambers on the skin is slightly smaller, and overall the size of the it increases from the opening to the end of the Dammam instrument. The chambers are pulled on the body to hold the skin in place, which is then pulled by the bandage that passes through it, and the Damman is tuned. Skin: Goat skin or tanned deer are used. Band: The strap is made of date or coconut fiber, which are called gash or kambal bands. The strap is imported from Africa or Mumbai, India. Drumstick : drumstick is made of wood and is made from the leaves of palm tree. Executive technique: The drumstick which is called the maze, is bent and placed in the player's right hand. The right and left hands are also complementary in creating rhythmic-metric symmetries, creating a kind of rhythmic conversation while playing. In ordinary Dammam, this coordination is simpler, and in Dammam, Ghambar and Ashkon become more complex, respectively. The right part, played by the maze, has a low volume, and the left part, played by the fingers, has a more penetrating sound. In group play, ordinary drums create the main bases of the rhythm flow, and the Ghambar Damman turn the bases into rhythmic buildings, and finally Dammam Ashkoun improvises to help the beauty of the rhythmic building, which plays a more difficult and important role than It has the rest of the dams. Administration: In recent decades, it has been used in Muharram and mourning ceremonies along with cymbals and trumpets. At the Muharram ceremony, the Dammam, cymbol and a horn are responsible for starting the ceremony. In the past, Dammam was used during sea work as a fishing whistle, as well as aerial music therapy ceremonies, a morning Dom Dom ritual performed at the dawn of Ramadan, and a sablo.
