The drum is a known member of the percussion band of musical devices. In the Hornbostel-Sachs classification system, this can be a membranophone.[1] Drums contain at least one membrane, called a drum or drumhead epidermis, that is extended more than a shell and struck, either immediately with the player's hands, or with a drum stick, to produce sound. There is usually a resonance head on the lower of the drum, tuned to a slightly lower pitch than the most notable drumhead typically. Other techniques have been used to cause drums to make sound, including the thumb roll. Drums will be the world's oldest and most ubiquitous musical equipment, and the basic design has remained almost unchanged for thousands of years.[1]Drums may independently be enjoyed, with the participant using a solo drum, and some drums including the djembe are almost played in this way always. Others are played in a set of several normally, all played by the one player, such as bongo timpani and drums. A number of different drums as well as cymbals form the essential modern drum kit.

Drums are performed by stunning with the side usually, or with a couple of sticks. In many traditional cultures, drums have a symbolic function and are used in religious ceremonies. Drums are often used in music therapy, especially hand drums, for their tactile characteristics and easy use by a wide variety of people.[2]In popular jazz and music, "drums" usually refers to a drum package or a set of drums (with some cymbals), and "drummer" to the individual who takes on them.Drums purchased divine position in places such as Burundi even, where the karyenda was a symbol of the incurred power of the king.Construction[edit]Drum carried by John Unger, Company B, 40th Regiment NY Veteran Volunteer Infantry Mozart Regiment, December 20, 1863The shell almost has a round opening over which the drumhead is extended invariably, but the shape of the remainder of the shell can vary widely. Inside the western musical traditions, the most typical shape 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 designed (djembe), and became a member of 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 contain a pores and skin extended over an enclosed space typically, or over one of the ends of the hollow vessel. Drums with two heads covering both ends of a cylindrical shell frequently have a small opening somewhat halfway between your two heads; the shell varieties a resonating chamber for the causing sound. Exceptions include 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, created from a metal barrel. Drums with two mind can have a set of cables also, called snares, organised across the bottom level head, top mind, or both relative heads, hence the name snare drum.[1]
DRUM poufs, footstools, tables
On modern band 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 kept through a number of tuning screws called "tension rods" that screw into lugs put evenly about the circumference. The head's tension can be changed by loosening or tensing the rods. Many such drums have six to ten tension rods. The audio of your drum will depend on many variables--including condition, shell thickness and size, shell materials, counterhoop material, drumhead material, drumhead anxiety, drum position, location, and dazzling velocity and viewpoint.[1]

Prior to the invention 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 hardly ever used, though sometimes seem on regimental marching strap snare drums.[1] The top of a 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 across the drum by ropes stretching from the very best to bottom head. Orchestral timpani can be quickly tuned to precise pitches by utilizing a foot pedal.Sound of the drum[edit]Several North 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, construction and shape of the drum shell, the type of drum heads it offers, and the strain of these drumheads. Different drum sounds 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 silent whereas a rock and roll drummer might prefer drums that are loud, dry and low-pitched. Since these drummers want different sounds, their drums are constructed a little differently.The drum brain gets the most effect how a drum sounds. Each type of drum head serves its musical purpose and has its unique sound. Double-ply drumheads dampen high regularity harmonics because they're heavier and they're suitable for heavy learning.[3] Drum minds with a white, textured finish about them muffle the overtones of the drum head slightly, creating a less diverse pitch. Drum heads with central sterling silver or black dots have a tendency to muffle the overtones even more. And drum minds with perimeter sound rings mainly eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum heads, preferring solitary ply drum minds or drum mind with no muffling

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