Hans Ruckers
The Ruckers family (variants: Ruckaert, Ruckaerts, Rucqueer, Rueckers, Ruekaerts, Ruijkers, Rukkers, Rycardt) were harpsichord and virginal makers from the Southern Netherlands based in Antwerp in the 16th and 17th century. Their influence stretched well into the 18th century, and to the harpsichord revival of the 20th. The Ruckers family contributed immeasurably to the harpsichord's technical development, pioneering the addition of a second manual; the quality of their instruments is such that the name of Ruckers is as important to early keyboard instruments as that of Stradivarius is to the violin family. In the 18th century, Ruckers instruments were often modified by French makers in a process known as ''ravalement'', to allow for an extended range and other additions. The Ruckers family The family probably originated in Germany. The earliest known member, Hans Ruckers, was from Weissenburg, according to documents from 1530 in the Antwerp city archives, and the similarly name ...

Harpsichord
A harpsichord ( it, clavicembalo; french: clavecin; german: Cembalo; es, clavecín; pt, cravo; nl, klavecimbel; pl, klawesyn) 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. The term denotes the whole family of similar plucked-keyboard instruments, including the smaller virginals, muselar, and spinet. ...

Plague (disease)
Plague is an infectious disease caused by the bacterium ''Yersinia pestis''. Symptoms include fever, weakness and headache. Usually this begins one to seven days after exposure. There are three forms of plague, each affecting a different part of the body and causing associated symptoms. Pneumonic plague infects the lungs, causing shortness of breath, coughing and chest pain; bubonic plague affects the lymph nodes, making them swell; and septicemic plague infects the blood and can cause tissues to turn black and die. The bubonic and septicemic forms are generally spread by flea bites or handling an infected animal, whereas pneumonic plague is generally spread between people through the air via infectious droplets. Diagnosis is typically by finding the bacterium in fluid from a lymph node, blood or sputum. Those at high risk may be vaccinated. Those exposed to a case of pneumonic plague may be treated with preventive medication. If infected, treatment is with antibiotic ...

Louis Couperin
Louis Couperin (; – 29 August 1661) was a French Baroque composer and performer. He was born in Chaumes-en-Brie and moved to Paris in 1650–1651 with the help of Jacques Champion de Chambonnières. Couperin worked as organist of the Church of St. Gervais in Paris and as musician at the court. He quickly became one of the most prominent Parisian musicians, establishing himself as a harpsichordist, organist, and violist, but his career was cut short by his early death at the age of thirty-five. None of Couperin's music was published during his lifetime, but manuscript copies of some 200 pieces survive, some of them only rediscovered in the mid-20th century. The first historically important member of the Couperin family, Couperin made contributions to the development of both the French organ school and the French harpsichord school. His innovations included composing organ pieces for specific registrations and inventing the genre of the unmeasured prelude for harpsichor ...

Bass (instrument)
A bass ( /beɪs/) musical instrument produces tones in the low-pitched range C4- C2. Basses belong to different families of instruments and can cover a wide range of musical roles. Since producing low pitches usually requires a long air column or string, the string and wind bass instruments are usually the largest instruments in their families or instrument classes. As seen in the musical instrument classification article, categorizing instruments can be difficult. For example, some instruments fall into more than one category. The cello is considered a tenor instrument in some orchestral settings, but in a string quartet it is the bass instrument. Examples grouped by general form and playing technique include: * Plucked string instruments, primary bass guitar and to a lesser extent acoustic bass guitar and even less often, folk instruments like contrabass guitar, guitarrón mexicano, tololoche, bass banjo or bass balalaika, instruments shaped, constructed and held (or worn) like ...

Chromatic
Diatonic and chromatic are terms in music theory that are most often used to characterize scales, and are also applied to musical instruments, intervals, chords, notes, musical styles, and kinds of harmony. They are very often used as a pair, especially when applied to contrasting features of the common practice music of the period 1600–1900. These terms may mean different things in different contexts. Very often, ''diatonic'' refers to musical elements derived from the modes and transpositions of the "white note scale" C–D–E–F–G–A–B. In some usages it includes all forms of heptatonic scale that are in common use in Western music (the major, and all forms of the minor). ''Chromatic'' most often refers to structures derived from the twelve-note chromatic scale, which consists of all semitones. Historically, however, it had other senses, referring in Ancient Greek music theory to a particular tuning of the tetrachord, and to a rhythmic notational convention in me ...

Timbre
In music, timbre ( ), also known as tone color or tone quality (from psychoacoustics), is the perceived sound quality of a musical note, sound or musical tone, tone. Timbre distinguishes different types of sound production, such as choir voices and musical instruments. It also enables listeners to distinguish different instruments in the same category (e.g., an oboe and a clarinet, both Woodwind instrument, woodwind instruments). In simple terms, timbre is what makes a particular musical instrument or human voice have a different sound from another, even when they play or sing the same note. For instance, it is the difference in sound between a guitar and a piano playing the same note at the same volume. Both instruments can sound equally tuned in relation to each other as they play the same note, and while playing at the same amplitude level each instrument will still sound distinctively with its own unique tone color. Experienced musicians are able to distinguish between diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiphonal
An antiphonary or antiphonal is one of the liturgical books intended for use (i.e. in the liturgical choir), and originally characterized, as its name implies, by the assignment to it principally of the antiphons used in various parts of the Latin liturgical rites. Medieval antiphonaries varied with regional liturgical tradition. In 1570, following the Council of Trent, the Roman Rite antiphonary was declared universal. The Roman Antiphonary (''Antiphonale Romanum'') contains the chants for the canonical hours for the hours of Lauds, Prime, Terce, Sext, None, Vespers and Compline for every day of the year. The ''Vesperale Romanum'' is an excerpt of the Antiphonary containing the chants sung at Vespers. The music for use at the Mass is contained in the Roman Gradual (''Graduale Romanum''), the chants of the ordinary are also edited as an excerpt from the Gradual, the ''Kyriale Romanum''. The ''Antiphonale Romanum'' was substantially revised in 1910–11 in the course of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch (music)
Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Perception Pitch and frequency Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its freq ...

Strings (music)
A string is the vibrating element that produces sound in string instruments such as the guitar, harp, piano (piano wire), and members of the violin family. Strings are lengths of a flexible material that a musical instrument holds under tension so that they can vibrate freely, but controllably. Strings may be "plain", consisting only of a single material, like steel, nylon, or gut, or wound, having a "core" of one material and an overwinding of another. This is to make the string vibrate at the desired pitch, while maintaining a low profile and sufficient flexibility for playability. The invention of wound strings, such as nylon covered in wound metal, was a crucial step in string instrument technology, because a metal-wound string can produce a lower pitch than a catgut string of similar thickness. This enabled stringed instruments to be made with less thick bass strings. On string instruments that the player plucks or bows directly (e.g., double bass), this enabled inst ...

Spinet
A spinet is a smaller type of harpsichord or other keyboard instrument, such as a piano or organ. Harpsichords When the term ''spinet'' is used to designate a harpsichord, typically what is meant is the ''bentside spinet'', described in this section. For other uses, see below. The bentside spinet shares most of its characteristics with the full-size instrument, including action, soundboard, and case construction. What primarily distinguishes the spinet is the angle of its strings: whereas in a full-size harpsichord, the strings are at a 90-degree angle to the keyboard (that is, they are parallel to the player's gaze); and in virginals they are parallel to the keyboard, in a spinet the strings are at an angle of about 30 degrees to the keyboard, going toward the right. The case of a bentside spinet is approximately triangular. The side on the right is usually bent concavely (hence the name of the instrument), curving away from the player toward the right rear corner. The long ...
