The drum is a known person in the percussion group of musical tools. In the Hornbostel-Sachs classification system, it is just a membranophone.[1] Drums consist of at least one membrane, called a drumhead or drum epidermis, that is stretched more than a shell and struck, either immediately with the player's hands, or with a drum keep, to produce sound. There's a resonance head on the underside of the drum usually, tuned to a just a bit lower pitch than the top drumhead typically. Other techniques have been used to cause drums to make sound, like the thumb roll. Drums will be the world's oldest and most ubiquitous musical instruments, and the basic design has remained unchanged for thousands of years virtually.[1]Drums may be performed singularly, with the gamer using a solo drum, and some drums such as the djembe are almost always played in this way. Others are usually played in a set of several, all played by the one player, such as bongo drums and timpani. A number of different drums together with cymbals form the basic modern drum kit.

Drums are usually performed by striking with the hand, or with one or two sticks. In many traditional civilizations, drums have a symbolic function and are being used in religious ceremonies. Drums are often used in music therapy, especially hand drums, because of their tactile aspect and easy use by a wide variety 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 individual who plays them.Drums acquired divine status in places such as Burundi even, where in fact the karyenda was a symbol of the energy of the king.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 beginning over that your drumhead is stretched, but the shape of the remainder of the shell can vary widely. In the western musical custom, the most usual form is a cylinder, although timpani, for example, use bowl-shaped shells.[1] Other shapes include a body design (tar, Bodhr?n), truncated cones (bongo drums, Ashiko), goblet formed (djembe), and became a member of truncated cones (discussing 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 skin area stretched over an enclosed space, or higher one of the ends of your hollow vessel. Drums with two minds covering both ends of an cylindrical shell often have a small opening somewhat halfway between the two mind; the shell varieties a resonating chamber for the resulting sound. Exceptions include the African slit drum, also called a log drum as it is made from a hollowed-out tree trunk, and the Caribbean material drum, made from a metal barrel. Drums with two minds can likewise have a couple of wiring, called snares, kept across the bottom level head, top mind, or both heads, hence the name snare drum.[1]

On modern music group and orchestral drums, the drumhead is located over the beginning of the drum, which is performed onto the shell with a "counterhoop" (or "rim"), which is then kept by means of lots of tuning screws called "tension rods" that screw into lugs put evenly surrounding the circumference. The head's pressure can be altered by loosening or tightening the rods. Many such drums have six to ten tension rods. The sound of an drum depends upon many variables--including form, shell size and thickness, shell materials, counterhoop materials, drumhead materials, drumhead tension, drum position, location, and striking viewpoint and speed.[1]

Towards the technology of pressure rods preceding, drum skins were fastened and tuned by rope systems--as on the Djembe--or pegs and ropes such as on Ewe Drums. These methods are almost never used today, though sometimes show up on regimental marching strap snare drums.[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 round the drum by ropes stretching from the most notable to bottom head. Orchestral timpani can be quickly tuned to precise pitches by by using a foot pedal.Sound of an drum[edit]Several American Indian-style drums for sale at the Country wide Museum of the North american Indian.Several factors determine the audio a drum produces, including the type, shape and construction of the drum shell, the sort of drum heads they have, and the tension of these drumheads. Different drum tones have different uses in music. Take, for example, the modern Tom-tom drum. A jazz drummer may want drums that are high pitched, resonant and peaceful whereas a rock drummer may like drums that are noisy, dry and low-pitched. Since these drummers want different sounds, their drums are constructed just a little differently.The drum head has the most effect how a drum does sound. Each kind of drum mind serves its own musical purpose and has its own unique audio. Double-ply drumheads dampen high regularity harmonics because they are heavier and they are suitable for heavy using.[3] Drum heads with a white, textured covering with them muffle the overtones of the drum mind slightly, producing a less diverse pitch. Drum mind with central silver or dark dots tend to muffle the overtones even more. And drum mind with perimeter sound rings mainly eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum mind, preferring one ply drum mind or drum minds without muffling

The second biggest factor that influences drum audio is head anxiety against the shell. When the hoop is put around the drum head and shell and tightened down with tension rods, the tension of the head can be modified. When the tension is increased, the amplitude of the audio is reduced and the frequency is increased, making the pitch higher and the volume lower.
