The drum is a known member of the percussion group of musical musical instruments. In the Hornbostel-Sachs classification system, it is a membranophone.[1] Drums consist of at least one membrane, called a drumhead or drum pores and skin, that is stretched over a shell and struck, either straight with the player's hands, or with a drum stay, to produce sound. There is usually a resonance head on the lower of the drum, typically tuned to a slightly lower pitch than the top drumhead. Other techniques have been used to cause drums to make sound, like the thumb roll. Drums are the world's oldest and most ubiquitous musical tools, and the basic design has remained practically unchanged for thousands of years.[1]Drums may be played out independently, with the gamer using a one drum, and some drums such as 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 timpani and drums. A number of different drums with cymbals form the essential modern drum set up collectively.

Drums are enjoyed by eye-catching with the hand usually, or with a couple of sticks. In lots of traditional cultures, drums have a symbolic function and are used in religious ceremonies. Drums are often used in music therapy, hand drums especially, because of their tactile character and easy use by a wide variety of people.[2]In popular music and jazz, "drums" usually identifies a drum system or a set of drums (with some cymbals), and "drummer" to the individual who performs them.Drums obtained divine status in places such as Burundi even, where the karyenda was symbolic of the recharged power of the ruler.Construction[edit]Drum taken by John Unger, Company B, 40th Regiment New York Veteran Volunteer Infantry Mozart Regiment, 20 december, 1863The shell almost has a round opening over that your drumhead is stretched invariably, but the form of the rest of the shell can vary widely. In the western musical traditions, the most standard shape 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 designed (djembe), and became a member of truncated cones (communicating drum).Drums with cylindrical shells can be open at one end (as is the situation with timbales), or can have two drum heads. Single-headed drums typically consist of a skin area stretched over an enclosed space, or over one of the ends of an hollow vessel. Drums with two heads covering both ends of your cylindrical shell often have a small hole somewhat halfway between your two heads; the shell varieties a resonating chamber for the resulting 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 steel drum, made from a metal barrel. Drums with two heads can have a couple of wire connections also, called snares, presented across the bottom head, top head, or both relative heads, the name snare drum hence.[1]
How to Tune A Drum. Good for Bass Drum Tuning, Snare Drum Tuning or
On modern music group and orchestral drums, the drumhead is put over the starting of the drum, which in turn is kept onto the shell with a "counterhoop" (or "rim"), which is then presented through lots of tuning screws called "tension rods" that screw into lugs positioned evenly throughout the circumference. The head's anxiety can be modified by loosening or tensing the rods. Many such drums have six to ten stress rods. The sound of any drum is determined by many variables--including shape, shell thickness and size, shell materials, counterhoop materials, drumhead materials, drumhead tension, drum position, location, and striking viewpoint and velocity.[1]

Before the invention of pressure 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 seldom used, though appear on regimental marching group snare drums sometimes.[1] The head 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 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 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 they have, and the strain of the drumheads. Different drum looks 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 tranquil whereas a rock drummer might like drums that are loud, low-pitched and dry. Since these drummers want different sounds, their drums are constructed just a little differently.The drum brain has the most effect how a drum tones. Each kind of drum head serves its own musical purpose and has its unique audio. Double-ply drumheads dampen high occurrence harmonics because they're heavier and they are suitable for heavy performing.[3] Drum heads with a white, textured finish about them muffle the overtones of the drum brain slightly, creating a less diverse pitch. Drum mind with central gold or black dots tend to muffle the overtones even more. And drum minds with perimeter sound rings typically eliminate overtones (Howie 2005). Some jazz drummers avoid using thick drum heads, preferring single ply drum heads or drum minds with no muffling

The next biggest factor that affects drum audio is head stress against the shell. When the hoop is placed around the drum head and shell and tightened down with tension rods, the tension of the head can be modified. When the tension is increased, the amplitude of the sound is reduced and the occurrence is increased, making the pitch higher and the quantity lower.
