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

Drums are played by stunning with the palm usually, or with one or two sticks. In many traditional civilizations, drums have a symbolic function and are being used in spiritual ceremonies. Drums are often used in music therapy, especially hand drums, for their tactile character and easy use by a multitude of people.[2]In popular jazz and music, "drums" usually identifies a drum package or a couple of drums (with some cymbals), and "drummer" to the individual who plays them.Drums received even divine position in places such as Burundi, where the karyenda was a symbol of the incurred ability of the ruler.Construction[edit]Drum transported by John Unger, Company B, 40th Regiment New York Veteran Volunteer Infantry Mozart Regiment, 20 december, 1863The shell almost has a circular starting over which the drumhead is extended invariably, but the shape of the remainder of the shell differs widely. Within the western musical custom, the most normal 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 molded (djembe), and became a member of truncated cones (chatting drum).Drums with cylindrical shells can be open at one end (as is the situation with timbales), or can have two drum mind. Single-headed drums typically consist of a skin stretched over a specific space, or higher one of the ends of any hollow vessel. Drums with two mind covering both ends of a cylindrical shell often have a small hole somewhat halfway between your two mind; the shell varieties a resonating chamber for the ensuing 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 material drum, created from a metal barrel. Drums with two minds can also have a couple of wiring, called snares, presented across the lower part head, top head, or both heads, hence the name snare drum.[1]

On modern group and orchestral drums, the drumhead is positioned over the starting of the drum, which in turn is presented onto the shell with a "counterhoop" (or "rim"), which is then held through a number of tuning screws called "tension rods" that screw into lugs positioned evenly throughout the circumference. The head's stress can be modified by loosening or tightening the rods. Many such drums have six to ten tension rods. The audio of the drum is determined by many variables--including shape, shell thickness and size, shell materials, counterhoop material, drumhead material, drumhead stress, drum position, location, and striking speed and angle.[1]

Towards the technology of pressure rods prior, 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 rarely used today, though appear on regimental marching music group snare drums sometimes.[1] The head of an 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 round the drum by ropes stretching from the top to bottom head. Orchestral timpani can be quickly tuned to precise pitches by utilizing a foot pedal.Sound of any drum[edit]Several American Indian-style drums for sale at the National Museum of the American Indian.Several factors determine the sound a drum produces, including the type, shape and construction of the drum shell, the kind of drum heads they have, and the strain of the 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 peaceful whereas a rock drummer might choose drums that are loud, dry and low-pitched. Since these drummers want different sounds, their drums differently are built a little.The drum head gets the most effect about how a drum noises. Each kind of drum brain serves its own musical goal and has its unique audio. Double-ply drumheads dampen high consistency harmonics because they're heavier and they are suitable for heavy using.[3] Drum heads with a white, textured coating in it muffle the overtones of the drum mind slightly, creating a less diverse pitch. Drum mind with central magic or dark-colored dots tend to muffle the overtones even more. And drum minds with perimeter audio rings mainly eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum mind, preferring solo ply drum heads or drum heads without muffling

The second biggest factor that impacts drum audio is head tension against the shell. When the hoop is located around the drum head and shell and tightened down with tension rods, the strain of the head can be modified. When the strain is increased, the amplitude of the audio is reduced and the rate of recurrence is increased, making the pitch higher and the volume lower.
