The drum is an associate of the percussion band of musical equipment. In the Hornbostel-Sachs classification system, it is just a membranophone.[1] Drums consist of at least one membrane, called a drumhead or drum skin area, that is stretched over the shell and struck, either immediately with the player's hands, or with a drum stick, to produce sound. There is usually a resonance at once the underside of the drum, tuned to a slightly lower pitch than the very best drumhead typically. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums will be the world's oldest and most ubiquitous musical instruments, and the basic design has remained unchanged for thousands of years virtually.[1]Drums may individually be played out, with the participant using a single drum, and some drums like 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 variety of drums with cymbals form the basic modern drum equipment together.

Drums are usually enjoyed by striking with the hands, or with a couple of sticks. In many traditional ethnicities, drums have a symbolic function and are used in spiritual ceremonies. Drums are often used in music therapy, especially hand drums, for their tactile aspect and easy use by a multitude of people.[2]In popular jazz and music, "drums" usually refers to a drum set up or a couple of drums (with some cymbals), and "drummer" to the individual who plays them.Drums attained even divine position in places such as Burundi, where the karyenda was a symbol of the energy of the king.Construction[edit]Drum taken 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 that your drumhead is extended, but the condition of the remainder of the shell can vary widely. In the western musical traditions, 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 (talking drum).Drums with cylindrical shells can most probably at one end (as is the situation with timbales), or can have two drum mind. Single-headed drums typically contain a epidermis stretched over a specific space, or higher one of the ends of any hollow vessel. Drums with two minds covering both ends of an cylindrical shell often have a small gap somewhat halfway between the two heads; the shell varieties a resonating chamber for the resulting 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 metal drum, made from a material barrel. Drums with two mind can have a set of cables also, called snares, organised across the bottom level head, top mind, or both heads, hence the name snare drum.[1]

On modern band and orchestral drums, the drumhead is positioned over the starting of the drum, which in turn is kept onto the shell by the "counterhoop" (or "rim"), which is then held through a number 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 tightening the rods. Many such drums have six to ten tension rods. The audio of the drum is determined by many variables--including condition, shell size and thickness, shell materials, counterhoop materials, drumhead material, drumhead anxiety, drum position, location, and attractive velocity and angle.[1]

Before the technology of anxiety rods, drum skins were fastened 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 strap snare drums sometimes.[1] The head of an talking drum, for example, can be temporarily tightened by squeezing the ropes that connect the top and bottom heads. Similarly, the tabla is tuned by hammering a disc held in place throughout the drum by ropes stretching from the very best to bottom head. Orchestral timpani can be tuned to precise pitches by utilizing a foot pedal quickly.Sound of the 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, like the type, shape and construction of the drum shell, the kind of drum heads it offers, and the strain of these drumheads. Different drum noises have different uses in music. Take, for example, the present day Tom-tom drum. A jazz drummer may want drums that are high pitched, resonant and tranquil whereas a rock drummer might favor drums that are loud, dry and low-pitched. Since these drummers want different sounds, their drums are constructed a little differently.The drum head has the most effect on how a drum does sound. Each kind of drum head serves its own musical goal and has its unique audio. Double-ply drumheads dampen high occurrence harmonics because they are heavier and they are suited to heavy learning.[3] Drum mind with a white, textured covering on them muffle the overtones of the drum mind slightly, creating a less diverse pitch. Drum minds with central metallic or dark dots have a tendency to muffle the overtones even more. And drum heads with perimeter sound rings mainly eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum minds, preferring one ply drum heads or drum mind with no muffling
The second biggest factor that influences drum sound is head pressure contrary to the shell. When the hoop is located around the drum head and shell and tightened down with tension rods, the strain of the top can be changed. When the strain is increased, the amplitude of the sound is reduced and the frequency is increased, making the pitch higher and the volume lower.
