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 on the shell and struck, either directly with the player's hands, or with a drum stay, to produce audio. There is usually a resonance head on the underside of the drum, tuned to a marginally lower pitch than the top drumhead typically. 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 tools, and the basic design has remained practically unchanged for thousands of years.[1]Drums may independently be performed, with the player using a solo drum, and some drums like the djembe are almost played in this way always. Others are usually played in a set of several, all played by the one player, such as bongo drums and timpani. A variety of drums with cymbals form the essential modern drum set up along.

Drums are played by impressive with the hand usually, or with one or two sticks. In lots of traditional civilizations, drums have a symbolic function and are used in religious ceremonies. Drums are often used in music therapy, hand drums especially, for their tactile aspect and easy use by a wide variety of people.[2]In popular jazz and music, "drums" usually identifies a drum equipment or a couple of drums (with some cymbals), and "drummer" to the person who takes on them.Drums bought even divine position in places such as Burundi, where the karyenda was a symbol of the power of the ruler.Construction[edit]Drum taken by John Unger, Company B, 40th Regiment New York Veteran Volunteer Infantry Mozart Regiment, December 20, 1863The shell almost invariably has a circular opening over that your drumhead is extended, but the condition of the remainder of the shell differs widely. Inside the western musical tradition, the most usual condition 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 shaped (djembe), and signed up with truncated cones (speaking drum).Drums with cylindrical shells can be open at one end (as is the case with timbales), or can have two drum minds. Single-headed drums typically consist of a skin stretched over a specific space, or higher one of the ends of your hollow vessel. Drums with two heads covering both ends of the cylindrical shell frequently have a small hole somewhat halfway between your two heads; the shell varieties a resonating chamber for the causing sound. Exceptions include the African slit drum, also known as a log drum as it is manufactured out of a hollowed-out tree trunk, and the Caribbean steel drum, made from a metallic barrel. Drums with two mind can likewise have a couple of wire connections, called snares, placed across the bottom head, top brain, or both heads, hence the name snare drum.[1]

On modern music group and orchestral drums, the drumhead is placed over the beginning of the drum, which is placed onto the shell by way of a "counterhoop" (or "rim"), which is then presented by means of lots of tuning screws called "tension rods" that screw into lugs positioned evenly surrounding the circumference. The head's tension can be fine-tuned by loosening or tightening up the rods. Many such drums have six to ten pressure rods. The sound of any drum depends on many variables--including form, shell thickness and size, shell materials, counterhoop material, drumhead materials, drumhead stress, drum position, location, and striking angle and speed.[1]

Prior to the invention of tension 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 almost never used, though seem on regimental marching band snare drums sometimes.[1] The head of the 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 throughout the drum by ropes stretching from the top to bottom head. Orchestral timpani can be tuned to precise pitches by by using a foot pedal quickly.Sound of any drum[edit]Several American Indian-style drums for sale at the Country wide Museum of the American Indian.Several factors determine the audio a drum produces, like the type, construction and shape of the drum shell, the kind of drum heads it has, and the strain of these drumheads. Different drum noises 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 peaceful whereas a rock and roll drummer might choose drums that are loud, dry and low-pitched. Since these drummers want different sounds, their drums in a different way are built just a little.The drum mind gets the most effect about how a drum looks. Each type of drum mind serves its musical purpose and has its own unique sound. Double-ply drumheads dampen high regularity harmonics because they are heavier and they're suitable for heavy playing.[3] Drum heads with a white, textured finish about them muffle the overtones of the drum brain slightly, creating a less diverse pitch. Drum minds with central metallic or black dots tend to muffle the overtones even more. And drum heads with perimeter audio rings largely eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum minds, preferring single ply drum mind or drum minds without muffling

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