The drum is a 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 skin, that is stretched over the shell and struck, either immediately with the player's hands, or with a drum keep, to produce sound. There is a resonance at once the underside of the drum usually, typically tuned to a marginally lower pitch than the very best drumhead. Other techniques have been used to cause drums to make sound, including the thumb roll. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained practically unchanged for thousands of years.[1]Drums may individually be played out, with the participant using a single drum, and some drums including 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 drums and timpani. A variety of drums together with cymbals form the basic modern drum kit.

Drums are performed by attractive with the hand usually, or with a couple of sticks. In many traditional cultures, drums have a symbolic function and are used in spiritual ceremonies. Drums are often used in music therapy, especially hand drums, for their tactile characteristics and easy use by a multitude of people.[2]In popular music and jazz, "drums" usually refers to a drum set up or a set of drums (with some cymbals), and "drummer" to the person who takes on 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 transported by John Unger, Company B, 40th Regiment NY Veteran Volunteer Infantry Mozart Regiment, 20 december, 1863The shell almost invariably has a circular starting over which the drumhead is stretched, but the shape of the remainder of the shell can vary widely. Within the western musical traditions, the most regular condition is a cylinder, although timpani, for example, use bowl-shaped shells.[1] Other shapes include a frame design (tar, Bodhr?n), truncated cones (bongo drums, Ashiko), goblet shaped (djembe), and signed up with truncated cones (discussing 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 skin area stretched over an enclosed space, or over one of the ends of your hollow vessel. Drums with two mind covering both ends of a cylindrical shell often have a small opening somewhat halfway between your two minds; 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 made from a hollowed-out tree trunk, and the Caribbean material drum, made from a steel barrel. Drums with two minds can have a couple of cables also, called snares, held across the bottom head, top head, or both heads, hence the name snare drum.[1]

On modern band and orchestral drums, the drumhead is placed over the starting of the drum, which in turn is performed onto the shell by way of a "counterhoop" (or "rim"), which is then performed through lots of tuning screws called "tension rods" that screw into lugs placed evenly round the circumference. The head's anxiety can be adjusted by loosening or tensing the rods. Many such drums have six to ten anxiety rods. The sound of the drum will depend on many variables--including form, shell thickness and size, shell materials, counterhoop material, drumhead materials, drumhead pressure, drum position, location, and dazzling viewpoint and speed.[1]
To the invention of tension rods previous, drum skins were attached and tuned by rope systems--as on the Djembe--or pegs and ropes such as on Ewe Drums. Today these methods are seldom used, though seem on regimental marching music group snare drums sometimes.[1] The head of any 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 set up round 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 North american Indian-style drums on the market at the National Museum of the American Indian.Several factors determine the audio a drum produces, including the type, shape and construction of the drum shell, the type of drum heads it offers, and the tension of the drumheads. Different drum tones 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 may like drums that are loud, dry and low-pitched. 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 kind of drum mind serves its musical goal and has its unique sound. Double-ply drumheads dampen high rate of recurrence harmonics because they're heavier and they're suited to heavy taking part in.[3] Drum mind with a white, textured coating in it muffle the overtones of the drum mind slightly, creating a less diverse pitch. Drum minds with central silver or black dots have a tendency to muffle the overtones even more. And drum heads with perimeter sound rings typically eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum minds, preferring solitary ply drum minds or drum mind with no muffling

The second biggest factor that affects drum audio is head anxiety resistant to the shell. When the hoop is put around the drum shell and head and tightened down with tension rods, the strain of the top can be fine-tuned. When the strain is increased, the amplitude of the audio is reduced and the frequency is increased, making the pitch higher and the quantity lower.
