Using computer aided design, Eriez has developed scrap drums with The drum is a member of the percussion group of musical tools. Within the Hornbostel-Sachs classification system, this can be a membranophone.[1] Drums contain at least one membrane, called a drumhead or drum skin, that is stretched more than a shell and struck, either directly with the player's hands, or with a drum stick, to produce audio. There is a resonance at once the lower of the drum usually, tuned to a slightly lower pitch than the top drumhead typically. Other techniques have been used to cause drums to make sound, like the thumb roll. Drums will be the world's oldest and most ubiquitous musical devices, and the basic design has remained nearly unchanged for thousands of years.[1]Drums may be played singularly, with the ball player using a sole drum, and some drums including the djembe are almost always played in this way. Others are normally played in a set of several, all played by the main one player, such as bongo timpani and drums. A number of different drums with cymbals form the basic modern drum equipment jointly.

In lots of traditional civilizations, drums have a symbolic function and are used in spiritual ceremonies. Drums are used in music remedy often, especially hand drums, because of their tactile nature and easy use by a wide variety of people.[2]In popular music and jazz, "drums" usually refers to a drum equipment or a couple of drums (with some cymbals), and "drummer" to the person who performs them.Drums bought even divine status in places such as Burundi, where the karyenda was a symbol of the energy of the ruler.Construction[edit]Drum carried by John Unger, Company B, 40th Regiment NY Veteran Volunteer Infantry Mozart Regiment, 20 december, 1863The shell almost has a circular opening over that your drumhead is stretched invariably, but the form of the remainder of the shell varies widely. In the western musical tradition, the most common 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 designed (djembe), and joined truncated cones (speaking 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 a specific space, or higher one of the ends of a hollow vessel. Drums with two minds covering both ends of a cylindrical shell frequently have a small gap somewhat halfway between the two mind; the shell forms a resonating chamber for the causing 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, made from a metal barrel. Drums with two minds can also have a couple of wiring, called snares, presented across the bottom head, top mind, or both relative heads, the name snare drum hence.[1]

SÁMI DRUMS  SHAMMANIC DRUMS  Lapland Drums  wulflund.comOn modern strap and orchestral drums, the drumhead is located over the opening of the drum, which in turn is kept onto the shell by the "counterhoop" (or "rim"), which is then held by means of lots of tuning screws called "tension rods" that screw into lugs located evenly across the circumference. The head's tension can be modified by loosening or tightening the rods. Many such drums have six to ten anxiety rods. The sound of an drum is determined by many variables--including condition, shell size and thickness, shell materials, counterhoop material, drumhead materials, drumhead stress, drum position, location, and dazzling speed and angle.[1]

 to make a steel drum plus some other fascinating steel drum factoidsBefore the technology of anxiety rods, 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 almost never used, though sometimes look on regimental marching music group snare drums.[1] The top of an 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 around the drum by ropes stretching from the very best to bottom head. Orchestral timpani can be tuned to precise pitches by by using a foot pedal quickly.Sound of an drum[edit]Several American Indian-style drums on the market at the National Museum of the American Indian.Several factors determine the sound a drum produces, like the type, construction and shape of the drum shell, the kind of drum heads it offers, and the tension of these drumheads. Different drum sounds have different uses in music. Take, for example, the modern Tom-tom drum. A jazz drummer may want drums that are high pitched, resonant and tranquil whereas a rock and roll drummer may choose drums that are noisy, dry and low-pitched. Since these drummers want different sounds, their drums are constructed a little differently.The drum brain has the most effect about how a drum tones. Each type of drum head serves its musical purpose and has its unique audio. Double-ply drumheads dampen high frequency harmonics because they're heavier and they are suitable for heavy performing.[3] Drum minds with a white, textured finish on them muffle the overtones of the drum head slightly, creating a less diverse pitch. Drum minds with central sterling silver or dark dots tend to muffle the overtones even more. And drum mind with perimeter sound rings mostly eliminate overtones (Howie 2005). Some jazz drummers stay away from thick drum mind, preferring solitary ply drum heads or drum heads without muffling

When the hoop is placed around the drum head and shell and tightened down with tension rods, the tension of the head can be changed. 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 volume lower.
