Fulcrum is a drumming term. Traditionally, the fulcrum refers to the part of a percussionist's grip that is the main lever for the drum stick to rotate. [1] This is usually created by the thumb and index finger, the thumb and middle finger, or a combination of the thumb, index, and middle fingers.
If one consciously locks their wrist, elbow, and shoulder so that they remain stationary, the only degree of freedom left to move the stick is the finger lever. The fulcrum, or point of rotation, will be located approximately where the pad of the thumb meets the stick. The thumb acts as the fulcrum while the other 4 fingers can apply mechanical forces to the stick. This lever is controlled with the smallest muscles and involves the least amount of mass in motion. Because there is less mass and less inertia, the fingers and thumb will be used to move the stick at high frequencies.
If one then locks the fingers in place by placing a tight grip on the stick the only way to raise and lower the stick is by rotating the wrist. The point of rotation is now somewhere in the middle of the wrist. The wrist is used to move the stick in larger motions leading to higher volume notes. The wrist is almost always used in conjunction with the fingers. If one were to hold their sticks or mallets with a 'death grip' while using only wrist rotation, there is the possibility of tendinitis or carpal tunnel syndrome occurring.
The forearm can be thought of as a shock absorber for the wrist and fingers. In general, the forearms will move slightly as a reaction to the forces the wrist and fingers are putting on the sticks. There is disagreement in the drum community regarding how much arm motion should be used. If one then freezes the wrist and finger levers they can move their stick, hand, and forearm by rotating at the elbow.
Each lever in the 'system' is suited to a particular purpose. In general they all work together to make up a 'correct' technique, allowing one to command their sticks/mallets to move exactly as they wish.
A pipette is a type of laboratory tool commonly used in chemistry and biology to transport a measured volume of liquid, often as a media dispenser. Pipettes come in several designs for various purposes with differing levels of accuracy and precision, from single piece glass pipettes to more complex adjustable or electronic pipettes. Many pipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid. Measurement accuracy varies greatly depending on the instrument.
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.
In baseball, a circle changeup or circle change is a pitch thrown with a grip that includes a circle formation, hence the name circle changeup. The circle is formed by making a circle with the index finger, holding the thumb at the bottom of the ball parallel to the middle finger and holding the ball far out in the hand. The ball is thrown turning the palm out.
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 handle is a part of, or attachment to, an object that allows it to be grasped and manipulated by hand. The design of each type of handle involves substantial ergonomic issues, even where these are dealt with intuitively or by following tradition. Handles for tools are an important part of their function, enabling the user to exploit the tools to maximum effect. Package handles allow for convenient carrying of packages.
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.
Finger spin is a type of bowling in the sport of cricket. It refers to the technique and specific hand movements associated with imparting a particular direction of spin to the cricket ball. The other spinning technique, generally used to spin the ball in the opposite direction, is wrist spin. Although there are exceptions, finger spinners generally turn the ball less than wrist spinners. However, because the technique is simpler and easier to master, finger spinners tend to be more accurate.
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.
A gee-haw whammy diddle is a mechanical toy consisting of two wooden sticks. One has a series of notches cut transversely along its side and a smaller wooden stick or a propeller attached to the end with a nail or pin. This stick is held stationary in one hand with the notches up, and the other stick is rubbed rapidly back and forth across the notches. This causes the propeller to rotate. Sometimes also known as a ouija windmill, a hoodoo stick or a VooDoo stick. The word whammy is sometimes whimmy, and the word diddle sometimes doodle, giving it three possible other names, and the gee-haw may also be dropped.
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.
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.
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking.
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.
