The drum is a member of the percussion band of musical devices. Within the Hornbostel-Sachs classification system, this is a membranophone.[1] Drums contain at least one membrane, called a drumhead or drum epidermis, that is extended over a shell and struck, either immediately with the player's hands, or with a drum keep, to produce audio. There is generally a resonance head on the underside of the drum, tuned to a just a bit lower pitch than the most notable drumhead typically. Other techniques have been used to cause drums to make sound, including the thumb roll. Drums are the world's oldest & most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years.[1]Drums may individually be enjoyed, with the gamer using a one drum, and some drums including the djembe are almost always played in this way. Others are played in a set of two or more normally, all played by the one player, such as bongo timpani and drums. A variety of drums with cymbals form the essential modern drum set together.

Drums are played out by dazzling with the hands usually, or with one or two sticks. In many traditional civilizations, drums have a symbolic function and are being used in religious ceremonies. Drums are used in music remedy often, hand drums especially, for their tactile aspect and easy use by a multitude of people.[2]In popular jazz and music, "drums" usually refers to a drum set or a set of drums (with some cymbals), and "drummer" to the person who performs them.Drums received even divine status in places such as Burundi, where in fact the karyenda was a symbol of the billed electricity of the ruler.Construction[edit]Drum transported by John Unger, Company B, 40th Regiment NY Veteran Volunteer Infantry Mozart Regiment, December 20, 1863The shell almost invariably has a circular opening over which the drumhead is extended, but the form of the remainder of the shell varies widely. Within the western musical tradition, the most usual form is a cylinder, although timpani, for example, use bowl-shaped shells.[1] Other designs include a frame design (tar, Bodhr?n), truncated cones (bongo drums, Ashiko), goblet shaped (djembe), and joined truncated cones (conversing drum).Drums with cylindrical shells can most probably at one end (as is the truth with timbales), or can have two drum minds. Single-headed drums typically contain a pores and skin stretched over a specific space, or higher one of the ends of your hollow vessel. Drums with two mind covering both ends of any cylindrical shell often have a small opening somewhat halfway between your two mind; the shell forms a resonating chamber for the resulting sound. Exceptions are the African slit drum, also known as a log drum as it is manufactured out of a hollowed-out tree trunk, and the Caribbean steel drum, created from a metal barrel. Drums with two minds can have a set of wire connections also, called snares, kept across the bottom level head, top brain, or both relative heads, the name snare drum hence.[1]

On modern music group and orchestral drums, the drumhead is located over the beginning of the drum, which is performed onto the shell by way of a "counterhoop" (or "rim"), which is then performed through a number of tuning screws called "tension rods" that screw into lugs located evenly round the circumference. The head's pressure can be modified by loosening or tensing the rods. Many such drums have six to ten tension rods. The sound of an drum depends on many variables--including shape, shell size and thickness, shell materials, counterhoop materials, drumhead material, drumhead stress, drum position, location, and striking velocity and position.[1]
NEW TECHNOLOGY: Bongo
Before the technology of stress rods, drum skins were attached and tuned by rope systems--as on the Djembe--or pegs and ropes such as on Ewe Drums. These methods are hardly ever used today, though appear on regimental marching band snare drums sometimes.[1] The head of an talking drum, for example, can be temporarily tightened by squeezing the ropes that hook up the bottom and top heads. Similarly, the tabla is tuned by hammering a disc held in place around the drum by ropes stretching from the most notable to bottom head. Orchestral timpani can be tuned to precise pitches by by using a foot pedal quickly.Sound of your drum[edit]Several North american Indian-style drums on the market at the Country wide Museum of the American Indian.Several factors determine the sound a drum produces, including the type, shape and construction of the drum shell, the type of drum heads it offers, and the strain of these drumheads. Different drum looks have different uses in music. Take, for example, the present day Tom-tom drum. A jazz drummer might want drums that are high pitched, resonant and calm whereas a rock and roll drummer may choose drums that are noisy, dry and low-pitched. Since these drummers want different sounds, their drums are constructed a little differently.The drum mind has the most effect on how a drum may seem. Each kind of drum mind serves its musical purpose and has its unique sound. Double-ply drumheads dampen high occurrence harmonics because they're heavier and they're suitable for heavy performing.[3] Drum minds with a white, textured layer to them muffle the overtones of the drum head slightly, producing a less diverse pitch. Drum minds with central sterling silver or black dots have a tendency to muffle the overtones even more. And drum mind with perimeter audio rings usually eliminate overtones (Howie 2005). Some jazz drummers avoid using thick drum minds, preferring solitary ply drum minds or drum minds with no muffling

The next biggest factor that affects drum audio is head tension contrary to the shell. When the hoop is located around the drum shell and head and tightened down with tension rods, the tension of the head can be tweaked. When the strain is increased, the amplitude of the sound is reduced and the occurrence is increased, making the pitch higher and the volume lower.
