The drum is an associate of the percussion group of musical equipment. In the Hornbostel-Sachs classification system, it is a membranophone.[1] Drums consist of at least one membrane, called a drumhead or drum skin area, that is extended over a shell and struck, either straight with the player's hands, or with a drum stay, to produce audio. There is usually a resonance at once the underside of the drum, tuned to a somewhat 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 tools, and the basic design has remained unchanged for thousands of years virtually.[1]Drums may individually be played, with the player using a one drum, and some drums such as the djembe are almost always played in this way. Others are normally played in a couple of two or more, all played by the one player, such as bongo timpani and drums. A number of different drums as well as cymbals form the basic modern drum kit.

Drums are usually played by stunning with the palm, or with a couple of sticks. In lots of traditional cultures, drums have a symbolic function and are being used in religious ceremonies. Drums are being used in music therapy often, especially hand drums, because of their tactile nature and easy use by a multitude of people.[2]In popular jazz and music, "drums" usually identifies a drum equipment or a couple of drums (with some cymbals), and "drummer" to the person who plays them.Drums attained divine status in places such as Burundi even, where in fact the karyenda was symbolic of the power 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 round starting over that your drumhead is extended, but the form of the rest of the shell ranges widely. Within the western musical custom, the most common condition is a cylinder, although timpani, for example, use bowl-shaped shells.[1] Other shapes include a structure design (tar, Bodhr?n), truncated cones (bongo drums, Ashiko), goblet molded (djembe), and joined up with truncated cones (speaking drum).Drums with cylindrical shells can most probably at one end (as is the case with timbales), or can have two drum heads. Single-headed drums consist of a epidermis extended over a specific space typically, or higher one of the ends of an hollow vessel. Drums with two mind covering both ends of the cylindrical shell frequently have a small gap somewhat halfway between the two minds; the shell forms a resonating chamber for the producing sound. Exceptions are the African slit drum, also called a log drum as it is manufactured out of a hollowed-out tree trunk, and the Caribbean material drum, made from a steel barrel. Drums with two mind can likewise have a set of wiring, called snares, kept across the bottom 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 starting of the drum, which in turn is placed onto the shell by way of a "counterhoop" (or "rim"), which is then organised by means of lots of tuning screws called "tension rods" that screw into lugs placed evenly surrounding the circumference. The head's tension can be modified by loosening or tightening up the rods. Many such drums have six to ten stress rods. The sound of any drum will depend on many variables--including shape, shell size and thickness, shell materials, counterhoop materials, drumhead materials, drumhead tension, drum position, location, and stunning velocity and position.[1]

Prior to the invention of anxiety rods, drum skins were attached and tuned by rope systems--as on the Djembe--or pegs and ropes such as on Ewe Drums. These procedures are rarely used today, though sometimes seem on regimental marching group snare drums.[1] The top of your talking drum, for example, can be temporarily tightened by squeezing the ropes that connect the bottom and top heads. Similarly, the tabla is tuned by hammering a disc held set up surrounding the drum by ropes stretching from the very best to bottom head. Orchestral timpani can be tuned to precise pitches by using a foot pedal quickly.Sound of a drum[edit]Several American Indian-style drums for sale at the National Museum of the American Indian.Several factors determine the audio a drum produces, like the type, shape and construction of the drum shell, the type of drum heads it offers, and the tension of these drumheads. Different drum may seem 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 might choose drums that are loud, low-pitched and dry. Since these drummers want different sounds, their drums in a different way are built just a little.The drum mind has the most effect about how a drum may seem. Each type of drum head serves its own musical purpose and has its unique audio. Double-ply drumheads dampen high frequency harmonics because they are heavier and they are suitable for heavy performing.[3] Drum heads with a white, textured covering on them muffle the overtones of the drum brain slightly, creating a less diverse pitch. Drum heads with central metallic or dark-colored dots have a tendency to muffle the overtones even more. And drum mind with perimeter sound rings usually eliminate overtones (Howie 2005). Some jazz drummers avoid using thick drum mind, preferring one ply drum mind or drum minds without muffling

The next biggest factor that influences drum sound is head pressure from the shell. When the hoop is placed around the drum shell and head and tightened down with tension rods, the strain of the top can be changed. When the tension is increased, the amplitude of the sound is reduced and the occurrence is increased, making the pitch higher and the quantity lower.
