The drum is a member of the percussion band of musical instruments. Within the Hornbostel-Sachs classification system, this is a membranophone.[1] Drums contain at least one membrane, called a drum or drumhead skin area, that is stretched over the shell and struck, either directly with the player's hands, or with a drum stay, to produce sound. There is usually a resonance at once the lower of the drum, typically tuned to a somewhat lower pitch than the very best drumhead. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums are the world's oldest & most ubiquitous musical tools, and the basic design has remained unchanged for thousands of years virtually.[1]Drums may individually be played out, with the player using a single drum, and some drums like the djembe are almost played in this way always. Others are played in a couple of two or more normally, all played by the one player, such as bongo timpani and drums. A variety of drums as well as cymbals form the essential modern drum kit.

Drums are usually enjoyed by stunning with the side, or with one or two sticks. In lots of traditional ethnicities, drums have a symbolic function and are being used in spiritual ceremonies. Drums are used in music therapy often, hand drums especially, because of their tactile character and easy use by a multitude of people.[2]In popular jazz and music, "drums" usually identifies a drum system or a couple of drums (with some cymbals), and "drummer" to the person who performs them.Drums purchased even divine status in places such as Burundi, where the karyenda was a symbol of the power of the ruler.Construction[edit]Drum transported by John Unger, Company B, 40th Regiment NY Veteran Volunteer Infantry Mozart Regiment, 20 december, 1863The shell almost invariably has a circular opening over that your drumhead is extended, but the shape of the remainder of the shell varies widely. In the western musical tradition, the most usual 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 molded (djembe), and joined truncated cones (conversing drum).Drums with cylindrical shells can be open at one end (as is the truth with timbales), or can have two drum heads. Single-headed drums typically contain a skin extended over an enclosed space, or over one of the ends of any hollow vessel. Drums with two heads covering both ends of the cylindrical shell often have a small hole somewhat halfway between the two heads; the shell varieties a resonating chamber for the causing sound. Exceptions include the African slit drum, also known as a log drum as it is made from a hollowed-out tree trunk, and the Caribbean steel drum, created from a material barrel. Drums with two mind can likewise have a set of cables, called snares, presented across the bottom head, top head, or both heads, hence the name snare drum.[1]

On modern group and orchestral drums, the drumhead is placed over the beginning of the drum, which is organised onto the shell by the "counterhoop" (or "rim"), which is then performed through a number of tuning screws called "tension rods" that screw into lugs put evenly throughout the circumference. The head's stress can be modified by loosening or tightening up the rods. Many such drums have six to ten tension rods. The audio of the drum depends upon many variables--including condition, shell size and thickness, shell materials, counterhoop material, drumhead material, drumhead stress, drum position, location, and attractive speed and angle.[1]
Before the invention of stress 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 procedures are seldom used, though sometimes show up on regimental marching music group snare drums.[1] The head of a talking drum, for example, can be temporarily tightened by squeezing the ropes that hook up the top and bottom heads. Similarly, the tabla is tuned by hammering a disc held in place surrounding the drum by ropes stretching from the most notable to bottom head. Orchestral timpani can be tuned to precise pitches by using a foot pedal quickly.Sound of an drum[edit]Several North american Indian-style drums for sale at the National Museum of the North american Indian.Several factors determine the sound a drum produces, like the type, shape and construction of the drum shell, the kind of drum heads it includes, and the strain of these drumheads. Different drum sounds 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 peaceful whereas a rock and roll drummer might like drums that are loud, low-pitched and dry. Since these drummers want different sounds, their drums are constructed just a little differently.The drum mind gets the most effect on how a drum does sound. Each type of drum brain serves its own musical goal and has its own unique audio. Double-ply drumheads dampen high frequency harmonics because they're heavier and they are suited to heavy playing.[3] Drum mind with a white, textured finish with them muffle the overtones of the drum mind slightly, producing a less diverse pitch. Drum heads with central gold or black dots tend to muffle the overtones even more. And drum minds with perimeter sound rings typically eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum minds, preferring single ply drum mind or drum minds with no muffling

The second biggest factor that influences drum audio is head tension against the shell. When the hoop is located around the drum shell and head and tightened down with tension rods, the tension of the top can be adjusted. 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.
