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

Drums are played by eye-catching with the palm usually, or with one or two 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 character and easy use by a wide variety of people.[2]In popular jazz and music, "drums" usually identifies a drum set or a set of drums (with some cymbals), and "drummer" to the person who plays them.Drums purchased even divine status in places such as Burundi, where in fact the karyenda was a symbol of the energy of the king.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 beginning over which the drumhead is extended, but the form of the rest of the shell ranges widely. In the western musical custom, the most typical condition is a cylinder, although timpani, for example, use bowl-shaped shells.[1] Other styles include a frame design (tar, Bodhr?n), truncated cones (bongo drums, Ashiko), goblet molded (djembe), and signed up with truncated cones (talking drum).Drums with cylindrical shells can be open at one end (as is the situation with timbales), or can have two drum mind. Single-headed drums typically consist of a skin area extended over an enclosed space, or higher one of the ends of an hollow vessel. Drums with two mind covering both ends of a cylindrical shell frequently have a small opening somewhat halfway between the two mind; the shell forms a resonating chamber for the producing sound. Exceptions are the African slit drum, also known as a log drum as it is manufactured out of a hollowed-out tree trunk, and the Caribbean material drum, created from a metallic barrel. Drums with two mind can have a set of wires also, called snares, placed across the bottom head, top mind, or both relative heads, the name snare drum hence.[1]

On modern band and orchestral drums, the drumhead is put over the starting of the drum, which in turn is held onto the shell with a "counterhoop" (or "rim"), which is then organised through a number of tuning screws called "tension rods" that screw into lugs placed evenly surrounding the circumference. The head's tension can be changed by loosening or tightening up the rods. Many such drums have six to ten stress rods. The audio of your drum depends upon many variables--including condition, shell size and thickness, shell materials, counterhoop materials, drumhead materials, drumhead stress, drum position, location, and stunning velocity and angle.[1]

Towards the invention of pressure rods prior, 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 rarely used, though show up on regimental marching band snare drums sometimes.[1] The head of any 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 round the drum by ropes stretching from the most notable to bottom head. Orchestral timpani can be tuned to precise pitches by using a foot pedal quickly.Sound of an drum[edit]Several North american Indian-style drums for sale at the National Museum of the North american Indian.Several factors determine the sound a drum produces, including the type, construction and form of the drum shell, the kind of drum heads it includes, and the strain of these drumheads. Different drum sounds 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 silent whereas a rock drummer may prefer drums that are loud, low-pitched and dry. Since these drummers want different sounds, their drums diversely are constructed just a little.The drum mind gets the most effect about how a drum does sound. Each type of drum brain serves its musical purpose and has its unique audio. Double-ply drumheads dampen high occurrence harmonics because they're heavier and they are suitable for heavy learning.[3] Drum heads with a white, textured coating with them muffle the overtones of the drum brain slightly, producing a less diverse pitch. Drum heads with central magic or black dots have a tendency to muffle the overtones even more. And drum mind with perimeter audio rings generally eliminate overtones (Howie 2005). Some jazz drummers avoid using thick drum minds, preferring one ply drum minds or drum heads without muffling

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