The drum is a member of the percussion group of musical devices. In the Hornbostel-Sachs classification system, it is a membranophone.[1] Drums consist of at least one membrane, called a drum or drumhead skin, that is extended over a shell and struck, either directly with the player's hands, or with a drum stay, to produce sound. There is a resonance at once the underside of the drum usually, tuned to a marginally lower pitch than the top drumhead typically. Other techniques have been used to cause drums to make sound, including the thumb roll. Drums are the world's oldest and most ubiquitous musical musical instruments, and the basic design has remained nearly unchanged for thousands of years.[1]Drums may independently be played, with the gamer using a sole drum, and some drums including the djembe are almost played in this way always. Others are normally played in a set of several, all played by the main one player, such as bongo drums and timpani. A number of different drums as well as cymbals form the essential modern drum kit.

Drums are usually performed by stunning with the side, or with one or two sticks. In many traditional cultures, drums have a symbolic function and are used in spiritual ceremonies. Drums are often used in music therapy, especially hand drums, because of their tactile characteristics and easy use by a wide variety of people.[2]In popular jazz and music, "drums" usually identifies a drum set or a set of drums (with some cymbals), and "drummer" to the person who performs them.Drums bought divine status in places such as Burundi even, where in fact the karyenda was a symbol of the power of the king.Construction[edit]Drum taken by John Unger, Company B, 40th Regiment New York Veteran Volunteer Infantry Mozart Regiment, December 20, 1863The shell almost invariably has a circular starting over that your drumhead is stretched, but the form of the rest of the shell differs widely. Inside the western musical traditions, the most standard form is a cylinder, although timpani, for example, use bowl-shaped shells.[1] Other designs include a body design (tar, Bodhr?n), truncated cones (bongo drums, Ashiko), goblet designed (djembe), and joined up with truncated cones (discussing 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 typically consist of 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 the cylindrical shell often have a small hole somewhat halfway between the two heads; the shell forms a resonating chamber for the producing sound. Exceptions include the African slit drum, also known as a log drum as it is manufactured out of a hollowed-out tree trunk, and the Caribbean metal drum, created from a steel barrel. Drums with two heads can also have a set of wire connections, called snares, kept across the bottom level head, top head, or both relative heads, the name snare drum hence.[1]
On modern band and orchestral drums, the drumhead is put over the opening of the drum, which is placed onto the shell by way of a "counterhoop" (or "rim"), which is then kept through a number of tuning screws called "tension rods" that screw into lugs positioned evenly surrounding the circumference. The head's anxiety can be tweaked by loosening or tensing the rods. Many such drums have six to ten stress rods. The audio of the drum will depend on many variables--including form, shell size and thickness, shell materials, counterhoop material, drumhead material, drumhead stress, drum position, location, and eye-catching velocity and viewpoint.[1]

Prior to the technology of pressure rods, drum skins were fastened and tuned by rope systems--as on the Djembe--or pegs and ropes such as on Ewe Drums. Today these methods are seldom used, though sometimes look on regimental marching strap 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 in place around the drum by ropes stretching from the most notable to bottom head. Orchestral timpani can be quickly tuned to precise pitches by using a foot pedal.Sound of your 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, construction and condition of the drum shell, the kind of drum heads it includes, and the strain of these drumheads. Different drum does sound have different uses in music. Take, for example, the modern Tom-tom drum. A jazz drummer might want drums that are high pitched, resonant and quiet whereas a rock drummer might like drums that are loud, low-pitched and dry. Since these drummers want different sounds, their drums in different ways are created just a little.The drum mind has the most effect on how a drum looks. Each kind of drum head serves its own musical goal and has its own unique sound. Double-ply drumheads dampen high rate of recurrence harmonics because they are heavier and they are suited to heavy using.[3] Drum heads with a white, textured layer to them muffle the overtones of the drum head slightly, creating a less diverse pitch. Drum minds with central silver precious metal or black dots tend to muffle the overtones even more. And drum heads with perimeter audio rings usually eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum heads, preferring sole ply drum heads or drum minds without muffling

The next biggest factor that influences drum audio is head stress contrary to the shell. When the hoop is located around the drum head and shell and tightened down with tension rods, the tension of the head can be adjusted. When the tension is increased, the amplitude of the sound is reduced and the rate of recurrence is increased, making the pitch higher and the quantity lower.
