The bassoon is a musical instrument in the woodwind family, which plays in the tenor and bass ranges. It is composed of six pieces, and is usually made of wood. It is known for its distinctive tone color, wide range, versatility, and virtuosity. It is a non-transposing instrument and typically its music is written in the bass and tenor clefs, and sometimes in the treble. There are two forms of modern bassoon: the Buffet and Heckel systems. It is typically played while sitting using a seat strap, but can be played while standing if the player has a harness to hold the instrument. Sound is produced by rolling both lips over the reed and blowing direct air pressure to cause the reed to vibrate. Its fingering system can be quite complex when compared to those of other instruments. Appearing in its modern form in the 19th century, the bassoon figures prominently in orchestral, concert band, and chamber music literature, and is occasionally heard in pop, rock, and jazz settings as well. One who plays a bassoon is called a bassoonist.
Embouchure or lipping is the use of the lips, facial muscles, tongue, and teeth in playing a wind instrument. This includes shaping the lips to the mouthpiece of a woodwind instrument or the mouthpiece of a brass instrument. The word is of French origin and is related to the root bouche, 'mouth'. Proper embouchure allows instrumentalists to play their instrument at its full range with a full, clear tone and without strain or damage to their muscles.
The harmonica, also known as a French harp or mouth organ, is a free reed wind instrument used worldwide in many musical genres, notably in blues, American folk music, classical music, jazz, country, and rock. The many types of harmonica include diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth to direct air into or out of one holes along a mouthpiece. Behind each hole is a chamber containing at least one reed. The most common is the diatonic Richter-tuned with ten air passages and twenty reeds, often called the blues harp. A harmonica reed is a flat, elongated spring typically made of brass, stainless steel, or bronze, which is secured at one end over a slot that serves as an airway. When the free end is made to vibrate by the player's air, it alternately blocks and unblocks the airway to produce sound.
Punch and Judy is a traditional puppet show featuring Mr. Punch and his wife Judy. The performance consists of a sequence of short scenes, each depicting an interaction between two characters, most typically Mr. Punch and one other character who usually falls victim to Punch's slapstick. The Daily Telegraph called Punch and Judy "a staple of the British seaside scene". The various episodes of Punch comedy—often provoking shocked laughter—are dominated by the clowning of Mr. Punch.
Snorkeling is the practice of swimming on or through a body of water while equipped with a diving mask, a shaped breathing tube called a snorkel, and usually swimfins. In cooler waters, a wetsuit may also be worn. The use of this equipment allows the snorkeler to observe underwater attractions for extended periods with relatively little effort and to breathe while face-down at the surface.
A tablet is a pharmaceutical oral dosage form or solid unit dosage form. Tablets may be defined as the solid unit dosage form of medication with suitable excipients. It comprises a mixture of active substances and excipients, usually in powder form, that are pressed or compacted into a solid dose. The main advantages of tablets are that they ensure a consistent dose of medicine that is easy to consume.
A dental dam or rubber dam is a thin, 6-inch (150 mm) square sheet, usually latex or nitrile, used in dentistry to isolate the operative site from the rest of the mouth. Sometimes termed "Kofferdam", it was designed in the United States in 1864 by Sanford Christie Barnum. It is used mainly in endodontic, fixed prosthodontic and general restorative treatments. Its purpose is both to prevent saliva interfering with the dental work, and to prevent instruments and materials from being inhaled, swallowed or damaging the mouth. In dentistry, use of a rubber dam is sometimes referred to as isolation or moisture control.
A perforation is a small hole in a thin material or web. There is usually more than one perforation in an organized fashion, where all of the holes collectively are called a perforation. The process of creating perforations is called perforating, which involves removing bits of the workpiece with a tool. Old-fashioned lick-and-stick postage stamps are perforated. When a tool makes small cuts in the material it's called 'rouletting', because that tool often resembles a roulette wheel, with blades around the edge. Raffle tickets are a good example of rouletting.
The reed switch is an electromechanical switch operated by an applied magnetic field. It was invented in 1922 by professor Valentin Kovalenkov at the Petrograd Electrotechnical University, and later evolved at Bell Telephone Laboratories in 1936 by Walter B. Ellwood into the reed relay. In its simplest and most common form, it consists of a pair of ferromagnetic flexible metal contacts in a hermetically sealed glass envelope. The contacts are usually normally open, closing when a magnetic field is present, or they may be normally closed and open when a magnetic field is applied. The switch may be actuated by an electromagnetic coil, making a reed relay, or by bringing a permanent magnet near it. When the magnetic field is removed, the contacts in the reed switch return to their original position. The "reed" is the metal part inside the reed switch envelope that is relatively thin and wide to make it flexible. It somewhat resembles part of some reed plants. The term "reed" may also include the external wire lead as well as the internal part.
A gag is a device used in sexual bondage and BDSM roleplay. Gags are usually associated with roleplays involving bondage, but that is not necessarily the case. The person who wears the gag is regarded as the submissive partner, while the other is regarded as the dominant one. People may wear gags for a variety of reasons. Some people derive erotic pleasure from a gag, either in a submissive or dominant role. When combined with other physical restraints, the wearing of a gag can increase the wearer's sense of helplessness and anxiety level within a BDSM scene by rendering them unable to speak during sexual activity, which some people enjoy.
A lobster trap or lobster pot is a portable trap that traps lobsters or crayfish and is used in lobster fishing. In Scotland, the word creel is used to refer to a device used to catch lobsters and other crustaceans. A lobster trap can hold several lobsters. Lobster traps can be constructed of wire and wood, or metal and netting or rigid plastic. An opening permits the lobster to enter a tunnel of netting or other one-way device. Pots are sometimes constructed in two parts, called the "chamber" or "kitchen", where there is bait, and exits into the "parlour", which prevents escape. Lobster pots are usually dropped to the sea floor, one or more at a time, sometimes up to 40 or more, and are marked by a buoy so they can be picked up later.
There are numerous techniques available for playing the harmonica, including bending, overbending, and tongue blocking.
The Continuum Fingerboard or Haken Continuum is a music performance controller and synthesizer developed by Lippold Haken, a professor of Electrical and Computer Engineering at the University of Illinois, and sold by Haken Audio, located in Champaign, Illinois.
Tonguing is a technique used with wind instruments to enunciate notes using the tongue on the palate or the reed or mouthpiece. A silent "tee" is made when the tongue strikes the reed or roof of the mouth causing a slight breach in the air flow through the instrument. If a more soft tone is desired, the syllable "da" is preferred. The technique also works for whistling. Tonguing also refers to articulation, which is how a musician begins the note and how the note is released For wind players, articulation is commonly spoken of in terms of tonguing because the tongue is used to stop and allow air to flow in the mouth. Tonguing does not apply to non wind instruments, but articulation does apply to all instruments.
An oropharyngeal airway is a medical device called an airway adjunct used in airway management to maintain or open a patient's airway. It does this by preventing the tongue from covering the epiglottis, which could prevent the person from breathing. When a person becomes unconscious, the muscles in their jaw relax and allow the tongue to obstruct the airway.
Capsule endoscopy is a medical procedure used to record internal images of the gastrointestinal tract for use in disease diagnosis. Newer developments are also able to take biopsies and release medication at specific locations of the entire gastrointestinal tract. Unlike the more widely used endoscope, capsule endoscopy provides the ability to see the middle portion of the small intestine. It can be applied to the detection of various gastrointestinal cancers, digestive diseases, ulcers, unexplained bleedings, and general abdominal pains. After a patient swallows the capsule, it passes along the gastrointestinal tract, taking a number of images per second which are transmitted wirelessly to an array of receivers connected to a portable recording device carried by the patient. General advantages of capsule endoscopy over standard endoscopy include the minimally invasive procedure setup, ability to visualize more of the gastrointestinal tract, and lower cost of the procedure.
A puppet is an object, often resembling a human, animal or mythical figure, that is animated or manipulated by a person called a puppeteer. The puppeteer buses movements of their hands, arms, or control devices such as rods or strings to move the body, head, limbs, and in some cases the mouth and eyes of the puppet. The puppeteer often speaks in the voice of the character of the puppet, and then synchronizes the movements of the puppet's mouth with this spoken part. The actions, gestures and spoken parts acted out by the puppeteer with the puppet are typically used in storytelling. Puppetry is a very ancient form of theatre which dates back to the 5th century BC in Ancient Greece. There are many different varieties of puppets, and they are made from a wide range of materials, depending on their form and intended use. They range from very simple in construction and operation to very complex.
A shepherd's whistle is a specialized, modulatable, variable-pitch whistle used to train and transmit commands to working dogs and other animals. Unlike other whistles, they are placed inside the mouth. The pitch is controlled by the placement of the tongue; physically, shepherd's whistles are vessel flutes with the tongue forming one side of the resonating chamber, and controlling its size. Like tin whistles, while simple, they can be used as musical instruments in their own right.
Saxophone technique refers to the physical means of playing the saxophone. It includes how to hold the instrument, how the embouchure is formed and the airstream produced, tone production, hands and fingering positions, and a number of other aspects. Instrumental technique and corresponding pedagogy is a topic of much interest to musicians and teachers and therefore has been subjected to personal opinions and differences in approach. Over the course of the saxophone's performance history, notable saxophonists have contributed much to the literature on saxophone technique.
A lisp is a speech impairment in which a person misarticulates sibilants. These misarticulations often result in unclear speech.
