The word dulcimer refers to two families of musical string instruments.
The hammered dulcimer is a percussion-stringed instrument which consists of strings typically stretched over a trapezoidal resonant sound board. The hammered dulcimer is set before the musician, who in more traditional styles may sit cross-legged on the floor, or in a more modern style may stand or sit at a wooden support with legs. The player holds a small spoon-shaped mallet hammer in each hand to strike the strings. The Graeco-Roman word dulcimer derives from the Latin dulcis (sweet) and the Greek melos (song). The dulcimer, in which the strings are beaten with small hammers, originated from the psaltery, in which the strings are plucked.
A harpsichord is a musical instrument played by means of a keyboard. This activates a row of levers that turn a trigger mechanism that plucks one or more strings with a small plectrum made from quill or plastic. The strings are under tension on a soundboard, which is mounted in a wooden case; the soundboard amplifies the vibrations from the strings so that the listeners can hear it. Like a pipe organ, a harpsichord may have more than one keyboard manual, and even a pedal board. Harpsichords may also have stop buttons which add or remove additional octaves. Some harpsichords may have a buff stop, which brings a strip of buff leather or other material in contact with the strings, muting their sound to simulate the sound of a plucked lute.
In musical instrument classification, string instruments, or chordophones, are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner.
Zithers are a class of stringed instruments. In modern terminology, it is more specifically an instrument consisting of many strings stretched across a thin, flat body, the topic of this article.
A psaltery is a fretboard-less box zither and is considered the archetype of the zither and dulcimer. Plucked keyboard instruments such as the harpsichord were also inspired by it. Its resonance box is usually trapezoidal, rectangular or in the form of a "pig's head" and often richly decorated.
The gusli is the oldest East Slavic multi-string plucked instrument, belonging to the zither family, due to its strings being parallel to its resonance board. Its roots lie in Veliky Novgorod in Novgorodian Republic. It has its relatives in Europe and throughout the world: kantele in Finland, kannel in Estonia, kanklės in Lithuania, kokles in Latvia, Zither in Germany, citera in the Czech Republic, and psalterium in France. Furthermore, the kanun has been found in Arabic countries, and the autoharp, in the United States. It is also related to such ancient instruments as Chinese gu zheng, which has a thousand-year history, and its Japanese relative koto. A stringed musical instrument called guslim is listed as one of the Me in ancient Sumer.
A key is a component of a musical instrument, the purpose and function of which depends on the instrument. However, the term is most often used in the context of keyboard instruments, in which case it refers to the exterior part of the instrument that the player physically interacts in the process of sound production.
The Appalachian dulcimer is a fretted string instrument of the zither family, typically with three or four strings, originally played in the Appalachian region of the United States. The body extends the length of the fingerboard, and its fretting is generally diatonic.
The trapezoidal yangqin is a Chinese hammered dulcimer, likely derived from the Iranian santur or the European dulcimer. It used to be written with the characters 洋琴, but over time the first character changed to 揚, which means "acclaimed". It is also spelled yang ch'in. Hammered dulcimers of various types are now very popular not only in China, but also Eastern Europe, the Middle East, India, Iran, and Pakistan. The instruments are also sometimes known by the names "santoor" and "cymbalom". This instrument had an influence on the Thai classical instrument, known as Khim (ขิม).
A socket wrench is a type of spanner that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt.
A variety of methods are used to tune different stringed instruments. Most change the pitch produced when the string is played by adjusting the tension of the strings.
The khim is a stringed musical instrument derived from the Mesopotamian or Persian Santur. It is similar to the Hammered Dulcimer or Cimbalom. This khim was introduced to Laos Thailand from China, where a similar instrument is called yangqin. It is played with two flexible bamboo sticks with soft leather at the tips to produce a soft tone. This instrument can be played by either sitting down on the floor with the khim on the floor, or by sitting on a chair or standing while the khim is on a stand. The khim produces a bright and expressive sound when played. It is made of wood, with brass strings that are laid across the instrument. The Australian-born musician and vocal artist Lisa Gerrard specialises in the use of a khim hammered dulcimer, featuring its music on several albums and performing with the instrument live on tour.
Salterio is the Italian, Spanish, and Portuguese term for either of two types of zither: the hammered dulcimer or psaltery.
An impact wrench is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft. It was invented by Robert H. Pott of Evansville, Indiana.
The piano action mechanism of a piano or other musical keyboard is the mechanical assembly which translates the depression of the keys into rapid motion of a hammer, which creates sound by striking the strings. Action can refer to that of a piano or other musical keyboards, including the electronic or digital stage piano and synthesizer, on which some models have "weighted keys", which simulate the touch and feel of an acoustic piano. The design of the key action mechanism determines the "weight" of the keys, i.e., the force required to sound a note; that is, the feeling of the heaviness of the touch of the keys. "A professional pianist is likely to care most about the piano's action, because that is what controls its responsiveness and relative lightness--or heaviness--of touch. Roughly speaking, a piano's action is light when its keys fall easily under the fingers, and heavy when a noticeable downward thrust is required. The action, in short, is what makes a piano playable or not to an individual musician."
Traditional Korean musical instruments comprise a wide range of string, wind, and percussion instruments. Many traditional Korean musical instruments derive from Chinese musical instruments.
The string drum or Tambourin de Béarn is a long rectangular box zither beaten with a mallet. It is paired with a one-handed flute with three finger holes, similar to a pipe and tabor. It has also been called tambourin de Gascogne, tambourin à cordes in Catalan, Pyrenean string drum, ttun-ttun in Basque, salmo in Spanish, and chicotén in Aragonese. It was known in the middle ages as the choron or chorus.
