The bass drum is a large drum that produces a note of low definite or indefinite pitch. The instrument is typically cylindrical, with the drum's diameter usually greater than its depth, with a struck head at both ends of the cylinder. The heads may be made of calfskin or plastic and there is normally a means of adjusting the tension, either by threaded taps or by strings. Bass drums are built in a variety of sizes, but size does not dictate the volume produced by the drum. The pitch and the sound can vary much with different sizes, but the size is also chosen based on convenience and aesthetics. Bass drums are percussion instruments that vary in size and are used in several musical genres. Three major types of bass drums can be distinguished.
Timpani or kettledrums are musical instruments in the percussion family. A type of drum categorised as a hemispherical drum, they consist of a membrane called a head stretched over a large bowl traditionally made of copper. Thus timpani are an example of kettledrums, also known as vessel drums and semispherical drums, whose body is similar to a section of a sphere whose cut conforms the head. Most modern timpani are pedal timpani and can be tuned quickly and accurately to specific pitches by skilled players through the use of a movable foot-pedal. They are played by striking the head with a specialized beater called a timpani stick or timpani mallet. Timpani evolved from military drums to become a staple of the classical orchestra by the last third of the 18th century. Today, they are used in many types of ensembles, including concert bands, marching bands, orchestras, and even in some rock bands.
A drum roll is a technique used by percussionists to produce a sustained sound for the duration of a written note.
All drum figures are based upon three fundamental beats, technically called roll, single stroke, and flam...Sustentation is accomplished upon wind instruments by blowing into the instrument; it is accomplished upon the violin and the allied instruments by drawing the bow across the string; it is accomplished upon the drum and allied percussion instruments by the roll.
THE SNARE DRUM ROLL.
The roll consists of an even reiteration of beats sufficiently rapid to prohibit rhythmic analysis. To produce an impression of sustentation, these beats must be absolutely even both in power and in sequence. Uneven beats in a roll destroy the impression of sustentation. Evenness is then the primary quality to strive for in roll; speed is the secondary quality to strive for.
There are two possible ways of producing an absolutely even sequence: (1) hand alternation of single stroke and (2) hand alternation of double strokes...The snare drum roll is produced by hand alternation of double strokes.
The "open roll" is produced by [initially] slow hand alternation. Two strokes in each hand alternately are produced by wrist movement and each beat should follow its predecessor in clock-like precision.
The upper limbs or upper extremities are the forelimbs of an upright-postured tetrapod vertebrate, extending from the scapulae and clavicles down to and including the digits, including all the musculatures and ligaments involved with the shoulder, elbow, wrist and knuckle joints. In humans, each upper limb is divided into the shoulder, arm, elbow, forearm, wrist and hand, and is primarily used for climbing, lifting and manipulating objects. In anatomy, just as arm refers to the upper arm, leg refers to the lower leg.
A splint is defined as "a rigid or flexible device that maintains in position a displaced or movable part; also used to keep in place and protect an injured part" or as "a rigid or flexible material used to protect, immobilize, or restrict motion in a part". Splints can be used for injuries that are not severe enough to immobilize the entire injured structure of the body. For instance, a splint can be used for certain fractures, soft tissue sprains, tendon injuries, or injuries awaiting orthopedic treatment. A splint may be static, not allowing motion, or dynamic, allowing controlled motion. Splints can also be used to relieve pain in damaged joints. Splints are quick and easy to apply and do not require a plastering technique. Splints are often made out of some kind of flexible material and a firm pole-like structure for stability. They often buckle or Velcro together.
Stevens grip is a technique for playing keyboard percussion instruments with four mallets developed by Leigh Howard Stevens. While marimba performance with two, four, and even six mallets had been done for more than a century, Stevens developed this grip based on the Musser grip, looking to expanded musical possibilities. Stevens codified his grip and his approach to performance techniques developed during his studies at the Eastman School of Music in his 1979 book, Method of Movement for Marimba. In this book, Stevens explains that his grip is an evolution of the Musser grip, and it is sometimes called the Musser-Stevens grip.
The Burton grip is a method of holding two mallets in each hand in order to play a mallet percussion instrument, such as a marimba or a vibraphone, using four mallets at once. It was developed by jazz vibraphonist Gary Burton around the 1960s.
Wrist spin is a type of bowling in the sport of cricket. It refers to the cricket technique and specific hand movements associated with imparting a particular direction of spin to the cricket ball. The other spinning technique, usually used to spin the ball in the opposite direction, is finger spin. Wrist spin is bowled by releasing the ball from the back of the hand, so that it passes over the little finger. Done by a right-handed bowler, this imparts an anticlockwise rotation to the ball, as seen from the bowler's perspective; a left-handed wrist spinner rotates the ball clockwise.
An armlock in grappling is a single or double joint lock that hyperextends, hyperflexes or hyperrotates the elbow joint or shoulder joint. An armpit lock is very useful; it will immobilize an opponent and pin them on the ground. An armlock that hyperextends the elbow is known as an armbar, and it includes the traditional armbar, the shoulder triangle armbar, and the shotgun armbar. An armlock that hyper-rotates the arm is known as an armcoil, and includes the americana, kimura, and omaplata. Depending on the joint flexibility of a person, armcoils can either hyperrotate only the shoulder joint, only the elbow joint, or both the elbow joint and shoulder joint.
A wristlock is a joint lock primarily affecting the wrist-joint and, in some cases, the radioulnar joints through rotation of the hand. A wristlock is typically applied by grabbing the opponent's hand, and bending and/or twisting it. Wristlocks are very common in martial arts such as chin-na, aikido, hapkido and jujutsu where they are featured as self-defense techniques. They are also used as submission holds in martial arts such as Brazilian jiu-jitsu and catch wrestling. While being an illegal technique in modern sambo and judo competitions, it is still practiced in judo forms of self-defense kata kōdōkan goshinjutsu. Wristlocks are also widely used as pain compliance holds, often in police, military, and residential treatment centers.
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes.
The Moeller method, Moeller technique or whipping technique is a percussive stroke method for drumming that combines a variety of techniques with the goal of improving hand speed, power, and control while offering the flexibility to add accented notes at will.
Hook grip is a method of gripping a barbell used in many strength-related sports such as Olympic weightlifting, Crossfit, and powerlifting by overlapping the index and middle finger over the thumb. This method of gripping the bar provides a secure bar grip while performing pulling motion with the barbell such as the clean and jerk, snatch, and deadlift. To perform a hook grip one must first wrap their thumb around the bar placing it parallel to the barbell and then wrap their index, and middle finger around the outside of the thumb. The pinky and ring finger typically ends up resting on the barbell. It is important to actively hooking on to the thumb with the index and middle finger while performing Hook grip compared to providing direct pressure on to the thumb.
In the sport of ten-pin bowling, there are many different ways in which to deliver the bowling ball in order to advance it toward the pins in an accurate and powerful manner. Generally, there are three basic forms of 10-pin bowling. The most basic form is known as stroking, which is the most classic form. The most powerful form is known as cranking, which imparts great leverage and maximum rotation on the ball, but sacrifices accuracy. In between the two is the domain of the tweener, who has characteristics of both, but does not truly fit into either category. A well-known variant of "tweening" is the power stroker.
A drum stick is a type of percussion mallet used particularly for playing snare drum, drum kit, and some other percussion instruments, and particularly for playing unpitched percussion.
The golf swing is the action by which players hit the ball in the sport of golf. The golf swing is a complex motion involving the whole body; the technicalities of the swing are known as golf stroke mechanics.
In music, a drum stroke is a movement which produces a single or multiple notes on drums or other percussion instruments such as cymbals. There are several types of strokes: five basic single strokes, double strokes, and other multiple strokes such as triples, quadruples, or buzzes of indeterminate number.
Injuries to the arm, forearm or wrist area can lead to various nerve disorders. One such disorder is median nerve palsy. The median nerve controls the majority of the muscles in the forearm. It controls abduction of the thumb, flexion of hand at wrist, flexion of digital phalanx of the fingers, is the sensory nerve for the first three fingers, etc. Because of this major role of the median nerve, it is also called the eye of the hand. If the median nerve is damaged, the ability to abduct and oppose the thumb may be lost due to paralysis of the thenar muscles. Various other symptoms can occur which may be repaired through surgery and tendon transfers. Tendon transfers have been very successful in restoring motor function and improving functional outcomes in patients with median nerve palsy.
In percussion, grip refers to the manner in which the player holds the sticks or mallets, whether drum sticks or other mallets.
The Fulcrum grip is a four-mallet grip for vibraphone and marimba developed by vibraphonist and educator Ed Saindon. The aim of the grip is to use varying fulcrum positions and finger technique to achieve the control, speed, and power of a two-mallet grip while being able to use all four mallets.
