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

Drums are usually played out by dazzling with the hand, or with a couple of sticks. In many traditional ethnicities, drums have a symbolic function and are used in religious ceremonies. Drums are often used in music therapy, especially hand drums, because of their tactile nature and easy use by a multitude of people.[2]In popular jazz and music, "drums" usually refers to a drum package or a couple of drums (with some cymbals), and "drummer" to the person who takes on them.Drums purchased even divine position in places such as Burundi, where in fact the karyenda was symbolic of the recharged vitality of the ruler.Construction[edit]Drum carried by John Unger, Company B, 40th Regiment New York Veteran Volunteer Infantry Mozart Regiment, 20 december, 1863The shell almost invariably has a round opening over which the drumhead is stretched, but the form of the remainder of the shell differs widely. Within the western musical custom, the most standard form is a cylinder, although timpani, for example, use bowl-shaped shells.[1] Other styles include a body design (tar, Bodhr?n), truncated cones (bongo drums, Ashiko), goblet formed (djembe), and joined truncated cones (communicating drum).Drums with cylindrical shells can most probably at one end (as is the case with timbales), or can have two drum mind. Single-headed drums typically consist of a pores and skin stretched over an enclosed space, 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 are the African slit drum, also called a log drum as it is made from a hollowed-out tree trunk, and the Caribbean steel drum, made from a steel barrel. Drums with two mind can likewise have a set of cables, called snares, performed across the bottom level head, top mind, 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 in turn is kept onto the shell by the "counterhoop" (or "rim"), which is then kept by means of lots of tuning screws called "tension rods" that screw into lugs positioned evenly surrounding the circumference. The head's stress can be fine-tuned by loosening or tensing the rods. Many such drums have six to ten anxiety rods. The audio of a drum depends on many variables--including form, shell thickness and size, shell materials, counterhoop materials, drumhead material, drumhead stress, drum position, location, and attractive velocity and viewpoint.[1]

Before the technology of stress rods, drum skins were attached and tuned by rope systems--as on the Djembe--or pegs and ropes such as on Ewe Drums. Today these procedures are hardly ever used, though appear on regimental marching group snare drums sometimes.[1] The top of any 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 across the drum by ropes stretching from the most notable to bottom head. Orchestral timpani can be quickly tuned to precise pitches by by using a foot pedal.Sound of your drum[edit]Several American Indian-style drums on the market at the Country wide 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 type of drum heads it offers, and the strain of the drumheads. Different drum does sound 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 tranquil whereas a rock drummer may choose drums that are noisy, low-pitched and dry. Since these drummers want different sounds, their drums are constructed just a little differently.The drum brain gets the most effect on how a drum noises. Each kind of drum head serves its own musical goal and has its unique audio. Double-ply drumheads dampen high regularity harmonics because they are heavier and they're suited to heavy learning.[3] Drum heads with a white, textured covering to them muffle the overtones of the drum brain slightly, producing a less diverse pitch. Drum mind with central silver or dark dots tend to muffle the overtones even more. And drum minds with perimeter audio rings typically eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum minds, preferring solo ply drum heads or drum minds without muffling

The second biggest factor that influences drum audio is head tension 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 adjusted. When the tension is increased, the amplitude of the sound is reduced and the consistency is increased, making the pitch higher and the volume lower.
