A tenor drum is a cylindrical drum that is higher pitched than a bass drum. In a symphony orchestra's percussion section, a tenor drum is a low-pitched drum, similar in size to a field snare, but without snares and played with soft mallets or hard sticks. Under various names, the drum has been used by composers since the mid-19th century. It is particularly noticeable in scores by 20th-century English composers such as Benjamin Britten and William Walton, and American composers such as Aaron Copland and Samuel Barber. ==Multi tenor drums== Tenor drums are used as a marching percussion instrument, commonly as mounted sets of 4-6 drums allowing one person to carry and play multiple drums simultaneously. Other names for these drums include the general "toms" and "timp toms", as well as names specific to configurations by number of drums: "duos" (2 drums), "tris", "trios", "trips", "triples" or "tri toms" (3 drums), "quads" or "quad toms" (4 drums), "quints" (5 drums), and "squints," "hexes," "six-packs," "tenors" or "sextets" (6 drums). The number-specific term "quads" is often used as a generic term even for configurations with more than four drums. Typically there are four main drums, usually either 8, 10, 12, and 13 inches in diameter (which is referred to as a ''high school'' configuration or small block tenors) or 10, 12, 13, and 14 inches in diameter (referred to as a ''Corps'' configuration or big block tenors), plus one or two accent drums (typically 6 or 8 inches in diameter)). The accent drums are also known as ''shot'', ''gock'', ''spock'', or ''spike'' drums; they are usually tightened as high as they can go to achieve maximum effect. Other percussion instruments, such as cowbells or cymbals mounted to the rim, are sometimes also added. The purpose of the tenors in the marching band is to add more color to the music. In big lines, there can be as many as 6 tenor players. Many high school marching bands will have one to three tenors, while it is typical for Division I drum corps to contain as many as five or six. They tend to supplement the snare part, and often the tenor parts are rudimentally identical to the snare parts. Movement around the drums allows tenors to function as melodic percussion, as each drum has a different pitch. A four drum configuration is typically arranged so that the lowest drum is to the player's far left, the second lowest is on the player's far right, the second highest is on the middle left, and the highest is on the middle right. This makes it easier to play common patterns, and is easier to balance than if the drums were in ascending size order. This arrangement is ideal for right-handed players and is almost always the arrangement in lines that consist of more than one tenor player for uniformity. If there is a fifth drum (often called the shot or spock drum) it is placed between the player and the highest two drums. If there are six drums, the fifth and sixth drum are centered closest to the player's body. Most of the time, tenor drums are tuned relatively tightly, giving them a high-pitched sound that carries well outdoors. Within the set of drums, the main drums are tuned to relative intervals (more common intervals being the minor 3rd, perfect 4th, and perfect 5th), while the accent drums are generally tuned as high as possible without breaking the head (often humorously referred to as "higher" and "highest", in the case of a 6-drum set). Tenor drums are played with mallets or drumsticks. A wide variety of implements are available, encompassing a full spectrum of shaft materials (hickory and aluminum are the most popular), head materials (wood, plastic/nylon, rubber, felt, and fleece "puffs" are all common), and head shape/size (ranging from large "cartwheel" discs, sometimes referred to as "cookie cutters", to traditional drum stick beads). Tenor players use matched grip. This facilitates tenor techniques such as "sweeps" or "scrapes" (playing double-bounce, or roll strokes in succession, while moving across different drums) and "crossovers" (crossing one hand over the other to reach a drum). These techniques allow an incredible variety of rhythmic and melodic figures possible on the tenors, as well as adding a distinct visual element to tenor playing. The drums are played near the edge of the head, like timpani, these areas are often called "zones". This allows for the optimum resonance and fundamental tone of the drum to project. Rim shots are not needed to be hit hard depending on the choice of sticks; hard hits can warp aluminum sticks. The player's sticks can move across the main four drums in a pattern that forms a straight line from drum-to-drum, or the closest part of the drum to the player's body. This reduces the amount of space the player must travel to execute some of the more complex movement patterns. It also allows for less upper arm motion from side-to-side, which streamlines movement to play patterns, and also makes it easier to balance the weight of the drums while marching, or even running, with the drums on. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「tenor drum」の詳細全文を読む スポンサード リンク
